[ detailed description ] embodiments

The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.

First, several terms referred to in the present application will be described.

Puncturing in a plane: the ultrasonic puncture method is characterized in that in the puncture process, the whole puncture needle is positioned in an ultrasonic beam plane of the ultrasonic device, and the ultrasonic image can display the puncture mode of the puncture path of the puncture needle.

Out-of-plane puncturing: the ultrasonic puncture method is characterized in that in the puncture process, the whole or part of the puncture needle is positioned outside an ultrasonic beam plane of the ultrasonic equipment, and the ultrasonic image can display a needle tip cross section image of the puncture needle or a puncture mode of a needle rod cross section.

Referring to fig. 1, for in-plane puncture, if the expected puncture position of the puncture needle is position 11, the conventional puncture needle monitoring method includes: the ultrasound image 12 at the position 11 is acquired by the probe and the puncture is performed in the ultrasound beam plane of the probe, at which time the ultrasound image 12 can display the puncture path of the puncture needle. The needle has reached position 11 in ultrasound image 12. However, in an actual scenario, the needle may have shifted in a direction perpendicular to the plane of the ultrasound beam (the plane indicated by the shaded portion), at which point the needle has not actually reached position 11.

Referring to fig. 2, for out-of-plane puncture, if the expected puncture location of the puncture needle is position 21, the conventional puncture needle monitoring method includes: the ultrasound image 22 of the location 21 is acquired by the probe and the puncture is made out of the plane of the ultrasound beam of the probe, at which time the ultrasound image 22 may display a cross-sectional image of the tip of the puncture needle when the puncture needle reaches the plane of the ultrasound beam, and the ultrasound image 22 may display a cross-sectional image of the needle shaft of the puncture needle when the tip of the puncture needle crosses the plane of the ultrasound beam.

In the puncture needle monitoring process, the puncture needle reaches the expected puncture position as long as a bright spot appears in the ultrasound image 22, but the bright spot cannot be further determined specifically by a cross-sectional image of the needle tip or a cross-sectional image of the needle rod. In the case where the bright spot is a cross-sectional image of the needle shaft, it is indicated that the needle has crossed position 21.

Therefore, the conventional puncture needle monitoring process has a problem that whether the puncture needle is used for in-plane puncture or out-of-plane puncture, whether the puncture needle deviates from the expected puncture position or not cannot be determined.

The desired puncture position is a position where the puncture needle is desired to reach in the target tissue. Such as: when a lesion area of a human body needs to be punctured, the puncture position is expected to be the position of the lesion area. For another example: when an intervention treatment needs to be performed on a blood vessel of a human body, the puncture position is expected to be the position of the blood vessel. In practical implementation, the desired puncturing position may be other positions of the target tissue, and the actual position of the desired puncturing position is not limited in this embodiment.

Based on the technical problems, the application provides an ultrasound scanning device, an ultrasound imaging device, a puncture needle monitoring method, a storage medium and a puncture needle monitoring system, and a plurality of scanning arrays are arranged on the ultrasound scanning device, so that the ultrasound imaging device can monitor whether a puncture needle exists at an expected puncture position or not and can also monitor whether a puncture needle exists at least one side of the expected puncture position or not, and therefore the position of the puncture needle relative to the expected puncture position can be determined, and the puncture accuracy is improved.

The following describes a needle monitoring system provided by the present application.

Fig. 3 is a schematic structural diagram of a needle monitoring system according to an embodiment of the present application, the system including at least: an ultrasound scanning device 310 and an ultrasound imaging device 320.

The ultrasound scanning apparatus 310 includes a transmit mode and a receive mode. In the transmit mode, the ultrasound scanning device 310 is capable of converting electrical energy into mechanical energy, the resulting mechanical waves propagating toward the medium and forming a beam plane inside the medium. In the receive mode, the ultrasound scanning device 310 receives the reflected mechanical waveform and is converted to an electrical signal by the ultrasound scanning device 310.

The ultrasound scanning device 310 may also be referred to as an ultrasound probe or a scanning probe, and the name of the ultrasound scanning device 310 is not limited in this embodiment.

In this embodiment, referring to fig. 4, the ultrasound scanning apparatus 310 includes: the first scanning array 311 further includes a second scanning array 312 and/or a third scanning array 313. That is, the ultrasound scanning apparatus 310 includes a first scanning array 311 and a second scanning array 312; alternatively, the ultrasound scanning apparatus 310 comprises a first scanning array 311 and a third scanning array 313; alternatively, the ultrasound scanning apparatus 310 includes a first scanning array 311, a second scanning array 312, and a third scanning array 313.

Each of the first scanning array 311, the second scanning array 312, and the third scanning array 313 includes at least one column of structural elements, and each element in each column of structural elements is arranged along the first direction.

The structural element may be a piezoelectric element, and in practical implementation, the piezoelectric element may also be another element capable of generating a mechanical wave.

In the second direction, the second scanning array and the third scanning array are respectively positioned at two sides of the first scanning array.

Wherein the second direction is perpendicular to the first direction.

The first scanning array 311 is configured to detect a target tissue position of the target object in the first beam plane, and obtain a first detection signal to form a first ultrasound image.

The target object can be a living body such as a human or an animal, and the target tissue position is an arbitrary position on the target object. Optionally, the target tissue location is determined based on a desired puncture location to which the puncture needle is desired to reach. In particular, the target tissue location is a tissue location that includes a desired puncture location. In other words, the first scanning array scans the desired puncture location as the puncture needle is monitored.

The second scanning array 312 is configured to detect the first tissue location on one side of the target tissue location in the second beam plane in the second direction, and obtain a second detection signal to form a second ultrasound image.

Since the second scanning array 312 is located at one side of the first scanning array 311 in the second direction, in the case where the first scanning array 311 scans the target tissue position, the second scanning array 312 may scan a position at one side of the target tissue position in the second direction.

And the third scanning array 313 is used for detecting a second tissue position on the other side of the target tissue position in a third beam plane in the second direction to obtain a third detection signal so as to form a third ultrasonic image.

Since the third scanning array 313 is located at the other side of the first scanning array 311 in the second direction, in the case where the first scanning array 311 scans the target tissue position, the third scanning array 313 can scan a position at the other side of the target tissue position in the second direction.

Wherein the first beam plane, the second beam plane, and the third beam plane are different beam planes. Optionally, at least two of the first beam plane, the second beam plane, and the third beam plane intersect or do not intersect, and the embodiment does not limit the implementation manner of the first beam plane, the second beam plane, and the third beam plane.

Alternatively, in the case where the first scanning array 311 is used to scan the desired puncture location, the imaging accuracy is generally high because the ultrasound image of the desired puncture location is also generally required for medical diagnosis by medical personnel; the ultrasound images obtained by the second scanning array 312 and the third scanning array 313 are only used for determining the position of the puncture needle relative to the expected puncture position, and therefore, the high precision is not required. Based on this, the number of structural elements in the first scanning array 311 is greater than the number of structural elements in the second scanning array 312, and the number of structural elements in the first scanning array 311 is greater than the number of structural elements in the third scanning array 313.

Optionally, the number of the target scanning arrays is N, and the target scanning array is a second scanning array or a third scanning array. N is a positive integer. In other words, the number of the second scanning arrays is one or at least two, and the number of the third scanning arrays is one or at least two. The corresponding beam planes of different target scanning arrays are different. Different beam planes are intersected or not intersected, and the implementation mode of the beam plane formed by scanning arrays of different targets is not limited in the embodiment.

The number of N is set based on the positioning precision requirement of the puncture needle. Specifically, the positioning accuracy requirement and the number of N are in a positive correlation relationship, that is, the higher the positioning accuracy requirement is, the larger the value of N is; the lower the positioning accuracy requirement, the smaller the value of N.

The array interval between two adjacent target scanning arrays is a first distance; the first distance is larger than the distance between two adjacent columns of structural elements in the target scanning array. Therefore, interference between two adjacent target scanning arrays can be avoided.

Optionally, the first distance is less than a third distance threshold, and the third distance threshold is determined based on positioning accuracy requirements of the puncture rack. Specifically, the value of the third distance threshold is in a negative correlation with the positioning accuracy requirement; that is, the higher the positioning accuracy requirement, the smaller the value of the third distance threshold; the lower the positioning accuracy requirement, the larger the value of the third distance threshold.

The minimum array spacing between the first scanned array and the target scanned array is a second distance. In other words, the array spacing between the first scanned array and the closest target scanned array to the first scanned array is a second distance.

The second distance is greater than the distance between two adjacent columns of structural elements in the target scanning array, and the second distance is greater than the distance between two adjacent columns of structural elements in the first scanning array. Therefore, interference between two adjacent target scanning arrays can be avoided, and interference between the first scanning array and the target scanning array which is far away from the first scanning array can be avoided.

Optionally, the second distance is less than a first distance threshold, the first distance threshold being determined based on positioning accuracy requirements of the puncture rack. Specifically, the value of the first distance threshold value and the positioning accuracy requirement are in a negative correlation relationship; that is, the higher the positioning accuracy requirement, the smaller the value of the first distance threshold; the lower the positioning accuracy requirement, the larger the value of the first distance threshold.

Optionally, the first distance and the second distance are the same or different, and illustratively, the first distance and the second distance are less than or equal to 3 millimeters (mm), and in actual implementation, values of the first distance and the second distance may also be other values, and the value of the first distance and the value of the second distance are not limited in this embodiment.

Optionally, the second scanning array is removably mounted on the ultrasound scanning apparatus 310 and the array distance of the second scanning array relative to the first scanning array is adjustable. And/or the third scanning array is detachably mounted on the ultrasonic scanning device 310, and the array distance of the third scanning array relative to the first scanning array is adjustable.

Such as: the second scanning array is installed on the ultrasonic scanning device 310 in a pluggable manner, the ultrasonic scanning device 310 has installation interfaces with various array pitches, and the installation interface used by the second scanning array is determined based on the positioning precision requirement.

For another example: the third scanning array is installed on the ultrasonic scanning device 310 in a pluggable manner, the ultrasonic scanning device 310 has installation interfaces with various array pitches, and the installation interface used by the third scanning array is determined based on the positioning precision requirement.

It should be added that the ultrasound scanning apparatus 310 may also include other structures that need to be used in the ultrasound scanning process, such as: transducers, connectors, and support structures, etc., and the present embodiment does not list the structures in the ultrasound scanning apparatus 310.

The ultrasound scanning device 310 is communicatively coupled to the ultrasound imaging device 320. Specifically, the ultrasound scanning device 310 and the ultrasound imaging device 320 may be communicatively connected on a wired or wireless basis. In practical implementation, the ultrasound scanning apparatus 310 and the ultrasound imaging apparatus 320 may be implemented in the same ultrasound apparatus, or may be used as apparatuses independent of each other, and the implementation manner of the ultrasound scanning apparatus 310 and the ultrasound imaging apparatus 320 is not limited in this embodiment.

The ultrasound imaging device 320 is configured to acquire the detection signals obtained by the ultrasound scanning device 310 and generate an ultrasound image based on the detection signals.

In this embodiment, referring to fig. 5, the ultrasound imaging apparatus 320 includes a processor 321, a memory 322 connected to the processor 321, and an output device 323 connected to the processor 321.

The memory 322 stores therein a program that is loaded and executed by the processor 321: acquiring a detection signal obtained by scanning of ultrasonic scanning equipment, wherein the ultrasonic scanning equipment comprises a first scanning array, and the detection signal comprises a first detection signal; the ultrasonic scanning equipment further comprises a second scanning array and/or a third scanning array, and correspondingly, the detection signals comprise second detection signals obtained by scanning the second scanning array and/or third detection signals obtained by scanning the third scanning array; generating a first ultrasonic image according to the first detection signal; an auxiliary ultrasound image is generated from the second detection signal and/or the third detection signal.

An output device 323 for outputting the first ultrasound image and the auxiliary ultrasound image. In this embodiment, the position of the puncture needle relative to the desired puncture position can be determined by the auxiliary ultrasound image, so that whether the puncture needle deviates from the desired puncture position or not can be identified.

In one example, after the output device 323 outputs the first ultrasound image and the auxiliary ultrasound image, the medical personnel manually determines the position of the puncture needle relative to the desired puncture location.

In another example, the processor 321 is further configured to determine whether the needle has reached the desired puncture location based on the first ultrasound image and the auxiliary ultrasound image, resulting in a needle monitoring result. In this example, the processor automatically monitors whether the puncture needle reaches the expected puncture position, so that the monitoring efficiency of the puncture needle can be improved.

The manner in which it is determined whether the needle has reached the desired puncture location based on the first and auxiliary ultrasound images is described below.

In one example, the puncture mode of the puncture needle is out-of-plane puncture, the ultrasound scanning device comprises a target scanning array, the target scanning array is a second scanning array or a third scanning array, and correspondingly, the auxiliary ultrasound image comprises an ultrasound image formed on the basis of detection signals obtained by scanning the target scanning array.

Determining whether the puncture needle reaches the expected puncture position or not based on the first ultrasonic image and the auxiliary ultrasonic image to obtain a puncture needle monitoring result, wherein the method comprises the following steps: if the puncture needle is not monitored in the first ultrasonic image and the auxiliary ultrasonic image, determining that the monitoring result of the puncture needle is that the puncture needle does not reach the expected puncture position; if the puncture needle is monitored in the first ultrasonic image, determining the monitoring result of the puncture needle as the fact that the puncture needle reaches the expected puncture position; if the puncture needle is monitored in the auxiliary ultrasonic image, when the puncture needle is monitored in the first ultrasonic image, the monitoring result of the puncture needle is determined to be that the puncture needle reaches the expected puncture position.

In other words, in the case where the puncture needle is not detected in both the first ultrasound image and the auxiliary ultrasound image, it is indicated that the puncture needle does not reach either the side of the desired puncture position or the desired puncture position. At the moment, the puncture needle monitoring result is determined to be that the puncture needle does not reach the expected puncture position. In practical implementation, the monitoring result of the puncture needle can be determined as the position corresponding to the scanning array of the puncture needle which does not reach the target.

When the puncture needle is monitored in the first ultrasonic image, namely, the puncture needle is not detected by the auxiliary ultrasonic image while the puncture needle is detected by the first ultrasonic image, the puncture needle enters from the first scanning array to the target scanning array, and then reaches the first scanning array and then reaches the target scanning array. At this time, the puncture needle monitoring result is determined as the arrival of the puncture needle at the desired puncture position. In practical implementation, the monitoring result of the puncture needle can be determined as the position corresponding to the scanning array of the puncture needle which does not reach the target.

When the puncture needle is monitored in the auxiliary ultrasound image, namely, the first ultrasound image does not detect the puncture needle when the auxiliary ultrasound image detects the puncture needle, at this time, the puncture needle enters from the target scanning array to the first scanning array, and reaches the target scanning array first and then reaches the first scanning array. At this time, the monitoring result of the puncture needle can be determined as the position corresponding to the arrival of the puncture needle at the target scanning array, and then when the puncture needle is monitored in the first ultrasonic image, the monitoring result of the puncture needle is determined as the arrival of the puncture needle at the expected puncture position.

Such as: taking the target scanned array as the second scanned array as an example, referring to fig. 6, a is a second beam plane formed by the second scanned array, and B is a first beam plane formed by the first scanned array. Wherein the first beam plane includes the desired puncture location. The puncture needle punctures in the direction from a to B as a puncture direction of the out-of-plane puncture, but does not reach a. At this time, neither the second ultrasound image 61 scanned by the second scanning array nor the first ultrasound image 62 scanned by the first scanning array includes a needle image. At the moment, the puncture needle monitoring result is determined to be that the puncture needle does not reach the expected puncture position. That is, the puncture needle does not reach the first beam plane indicated by B.

Thereafter, the puncture needle continues to be inserted into the target tissue, and referring to fig. 7, the direction in which the puncture needle performs puncture in an out-of-plane puncture is a puncture from a to B, and has already reached a.

After the puncture needle state shown in fig. 8, the puncture needle continues to be inserted into the target tissue, and referring to fig. 9, the puncture needle performs puncture in the direction from a to B to C in the out-of-plane puncture, and has already reached C. At this point, the first scannable array scans to a first ultrasound image 91 that includes a needle image, i.e., a cross-sectional image of the needle shaft (shown as a bright spot in 91).

Specifically, the binarization processing of the first ultrasound image and the auxiliary ultrasound image can be represented by the following formula:

wherein, V_oFor updated pixel values, V_iIs the pixel value of the ith pixel point in the ultrasonic image, i is a positive integer, V_tIs a preset pixel threshold. The pixel threshold may be set based on empirical values, or it may be when the ultrasound image does not include a needle imageThe minimum pixel value, in this embodiment, does not limit the value of the pixel threshold.

The display manner is only exemplary, and in actual implementation, the display manner and the implementation manner of the preset icon may be other manners, and the preset icon and the icon display manner are not limited in this embodiment.

Optionally, the output device 323 further comprises an audio player. The audio player is used for outputting audio prompts according to the puncture needle monitoring results, and the audio prompts output by different puncture needle monitoring results are different.

Such as: when the puncture needle monitoring result is that the puncture needle does not reach the expected puncture position, the audio prompt is a buzzer sound with a first frequency; when the puncture needle monitoring result is that the puncture needle reaches the expected puncture position, the audio prompt is a buzzer sound of a second frequency; and when the puncture needle monitoring result is that the puncture needle passes the expected puncture position, the audio prompt is a buzzer sound of a third frequency. The first frequency is lower than the second frequency and lower than the third frequency. When the puncture needle monitoring result is that the puncture needle deviates from the second scanning array, the audio prompt is a continuous buzzing sound with a first volume; and when the puncture needle monitoring result is that the puncture needle deviates to the third scanning array, the audio prompt is a continuous buzzing sound with a second volume, and the first volume is different from the second volume.

At the moment, the processor is also used for determining the installation position of the puncture needle on the puncture frame based on the expected puncture position; and the output device is also used for outputting the mounting position.

The mounting position may be represented by a number of the auxiliary puncture structure on the puncture rack, or may be represented by a rank number of the auxiliary puncture structure on the puncture rack.

Alternatively, the desired puncture position may be a position at which the ultrasound imaging apparatus displays the first ultrasound image and receives a selection operation for an image position on the first ultrasound image, the selection operation indicating; alternatively, the desired puncture location may be obtained by the ultrasound imaging apparatus using an image recognition algorithm to perform image recognition on the first ultrasound image. The image recognition algorithm may be a target recognition algorithm based on a neural network, the neural network is obtained based on the sample ultrasound image and the puncture position label training corresponding to the sample ultrasound image, and the embodiment does not limit the acquisition mode of the expected puncture position.

In one example, the memory stores puncture rack models of respective puncture racks, an erection angle and an erection position of the puncture rack for each puncture rack model. At this time, the method for determining the mounting position of the puncture needle on the puncture rack based on the expected puncture position comprises the following steps: acquiring the type of a puncture frame of the puncture frame; and under the condition of determining the type of the puncture frame, erecting an auxiliary puncture structure with the angle and the erecting position matched with the expected puncture position, wherein the position of the auxiliary puncture structure is the installation position.

Referring to fig. 14, if the distance between the puncture rack 330 and the scanning plane of the ultrasound scanning apparatus is known as H and the desired puncture position is 141, the distance d from the mounting position of an auxiliary puncture structure to the first beam plane is known for the type of the puncture rack, and the depth H of the first beam plane that can be reached by the auxiliary puncture structure can be calculated from the mounting angle of the auxiliary puncture structure. If the depth h is consistent with the puncture depth indicated by the expected puncture position, determining that the auxiliary puncture structure is matched with the expected puncture position; if the depth h does not correspond to the puncture depth indicated by the desired puncture location, it is determined that the auxiliary puncture structure does not match the desired puncture location.

In other examples, determining the mounting location of the needle on the puncture carriage based on the desired puncture location includes: for each puncture frame model, determining whether an auxiliary puncture structure with an erection angle and an erection position matched with an expected puncture position is included under the puncture frame model, wherein the position of the auxiliary puncture structure matched with the expected puncture position is an installation position; outputting a puncture rack model with an auxiliary puncture structure matching the desired puncture location.

Accordingly, the processor is further configured to determine, in the installed position of the puncture needle 340, the needle insertion depth of the puncture needle based on the desired puncture position; the output device is also used for outputting the needle insertion depth.

Referring to fig. 14, determining the needle insertion depth of the puncture needle based on the desired puncture location includes: calculating the sum of the depth H of the expected puncture position and the installation height H of the puncture rack 330; based on the pythagorean theorem, the needle insertion depth is calculated using the height and the distance d from the setup position to the first beam plane.
