Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The scanning method provided by the application can be applied to the scanning system shown in fig. 1. The scanning system includes: the system comprises at least one physiological signal acquisition device 102, a control terminal 104 and a scanning device 106, wherein the control terminal 104 is respectively communicated with the physiological signal acquisition device 102 and the scanning device 106 through a wired or wireless network; the physiological signal collecting device 102 may specifically be a respiratory signal collecting device, or may also be a heartbeat signal collecting device, for example, if the physiological signal collecting device 10 is a respiratory signal collecting device, it may specifically be a respiratory bandage as shown in fig. 1A, or a millimeter wave signal collecting device as shown in fig. 1B; the scanning device 106 may be any type of image scanning device, such as Computed Tomography (CT), Magnetic Resonance Imaging (MRI), etc.; the control terminal 104 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices.
It will be appreciated by those skilled in the art that the configuration shown in fig. 1 is a block diagram of only a portion of the configuration relevant to the present teachings and does not constitute a limitation on the scanning system to which the present teachings are applied, and that a particular scanning system may include more or less components than those shown, or combine certain components, or have a different arrangement of components.
In one embodiment, as shown in fig. 2, a scanning method is provided, which is described by taking the example that the method is applied to the control terminal in fig. 1, and includes the following steps:
s101, at least two physiological signal sources are detected.
The physiological signal source may be a respiration signal source or a heartbeat signal source. When the physiological signal source is a breathing signal source, the breathing signal can come from different types of breathing signal sources such as a breathing bandage collecting device and a millimeter wave collecting device; when the physiological signal source is a heartbeat signal source, the heartbeat signal can come from a heartbeat signal source such as an electrocardio tester.
In this embodiment, the control terminal is connected to at least two physiological signal sources and the scanning device in advance, where the at least two physiological signal sources may be the same type of signal source or different types of signal sources, for example, both are respiratory signal sources or heartbeat signal sources, or part of the physiological signal sources is respiratory signal sources and part of the physiological signal sources is heartbeat signal sources. When the control terminal controls the scanning device to scan the patient in advance, especially when a specific part (chest and abdomen) of the patient is scanned, the control terminal can detect the physiological signal sources first and detect the number of the physiological signal sources, so as to determine the physiological signal sources to be used from the detected physiological signal sources to sample the physiological signals.
S102, selecting one physiological signal source from more than two physiological signal sources as a target signal source according to a preset selection mode.
The preset selection mode may include one of a manual selection mode and an automatic selection mode. The target signal source is a signal source for assisting the scanning device to scan.
When the control terminal detects more than two physiological signal sources, selecting one physiological signal source from the more than two physiological signal sources as a target signal source according to a preset selection mode, specifically, optionally selecting one physiological signal source as the target signal source; optionally, a physiological signal source may also be selected as the target signal source according to a preset signal source type.
S103, acquiring physiological signals of a target area acquired by a target signal source.
Wherein the physiological signal comprises a respiration signal or a heartbeat signal. The respiration signal can be acquired by using a respiration signal source, and the heartbeat signal can be acquired by using a heartbeat signal source. The target region refers to a scanning region when the scanning apparatus scans a patient, and also refers to a region where a specific part of the patient is located. The specific region refers to a thoracoabdominal region of the patient, or a region including the thoracoabdominal region.
In this embodiment, the target signal source may be first started to collect the physiological signal of the target area, which is the area where the specific portion of the patient is located, in real time, and then the control terminal is started to obtain the collected physiological signal from the target signal source, which includes the signal intensity of the physiological signal, the signal period of the physiological signal, and the signal waveform of the physiological signal. For example, in practical applications, a breathing signal of a patient may be acquired by using a breathing strap, and then the control terminal acquires the breathing signal from the breathing strap by connecting the breathing strap, wherein the breathing signal includes a signal intensity, a signal period, a signal waveform, a breathing rate, and the like of the breathing signal. It should be noted that the control terminal may also be activated simultaneously with the target signal source, so that the control terminal can synchronously acquire the physiological signal from the target signal source.
Optionally, the control terminal may display the physiological signals acquired by the physiological signal sources on a display interface, for example, as shown in fig. 2A, a breath B represents the physiological signal acquired by a breathing band, a breath V represents the physiological signal acquired by the millimeter waves, and the page includes, from left to right: signal source selection, waveform display period, respiratory waveform and trigger scanning point indication (white triangle), respiratory rate and respiratory period display and physiological signal acquisition equipment state. It should be noted that, the control terminal is installed with scanning software, and the scanning software can be used to provide a display interface for displaying the physiological signals collected by the physiological signal sources, so that a user can view various parameter indexes of the physiological signals on the display interface.
And S104, triggering the scanning device to scan and image the target area according to the physiological signal.
In this embodiment, when the control device acquires the physiological signal acquired by the target signal source, a scanning mode may be set according to the physiological signal, and then the scanning device is instructed to start a scanning function according to the scanning mode to scan and image the target area.
In the scanning method provided by the above embodiment, when more than two physiological signal sources are detected, one physiological signal source is selected from the more than two physiological signal sources as a target signal source according to a preset selection mode, then the physiological signal of the target area is acquired by the target signal source, and finally, the scanning device is triggered to scan and image the target area according to the physiological signal. The scanning method can assist the scanning equipment in imaging by selecting the physiological signals acquired by the reliable physiological signal source, can effectively remove the motion artifacts caused by the scanning equipment when scanning the target area, and improves the quality of the scanned images of the scanning equipment.
Optionally, an implementation manner of the S102 is provided, as shown in fig. 3, where the S101 "selects one physiological signal source from two or more physiological signal sources as a target signal source according to a preset selection manner," includes:
and S201, if the selection mode is an automatic selection mode, determining a target signal source according to the signal intensity of each physiological signal source in more than two physiological signal sources.
The selection mode can be provided by the control terminal in advance, and can be determined by a doctor.
In this embodiment, a selection mode may be set by a doctor through human-computer interaction with the control terminal, for example, the doctor selects an automatic selection mode on a display interface, or the control terminal determines the selection mode as the automatic selection mode by default, in this case, the control terminal may automatically select one physiological signal source from more than two connected physiological signal sources as a target signal source, and specifically, during automatic selection, the selection may be determined according to signal intensity of the physiological signal acquired by each physiological signal source.
Optionally, a specific implementation manner of "determining the target signal source according to the signal strength of each of the two or more physiological signal sources" in S201 is provided, that is, the physiological signal source with the signal strength greater than the first preset strength threshold value among the two or more physiological signal sources is taken as the target signal source.
The first preset intensity threshold may be determined by the control terminal in advance according to an actual scanning requirement.
In this embodiment, the control terminal can compare the signal intensity of the physiological signal of each physiological signal source with a first preset intensity threshold, and using the physiological signal source with the signal intensity larger than the first preset intensity threshold value as a target signal source, in one application, if a plurality of selected physiological signal sources are greater than the first preset intensity threshold, then correspondingly randomly selecting one physiological signal source from the plurality of physiological signal sources as a target signal source, or selecting one physiological signal source as the target signal source according to the type of the equipment, for example, the control terminal detects that two signal sources exist, one is a respiration A signal source, the other is a respiration B signal source, if the control terminal detects that the physiological signal intensity of the respiration A signal source is greater than a first preset intensity threshold value, and the respiration B signal source is smaller than the first preset intensity threshold value, the control terminal directly selects the respiration A signal source as a target signal source; for another example, if it is detected that the physiological signal intensity of the respiration a signal source is greater than the first preset intensity threshold and the respiration B signal source is greater than the first preset intensity threshold, the respiration a signal source is determined as the target signal source because the respiration a signal source is the millimeter wave respiration acquisition device.
S202, if the selection mode is a manual selection mode, determining a target signal source according to a selection instruction input by a doctor.
In this embodiment, a doctor may set a selection mode through human-computer interaction with the control terminal, for example, the doctor selects a manual selection mode on a display interface, or determines the selection mode as the manual selection mode by default, and in this case, the doctor may input a selection instruction on the human-computer interaction interface of the control terminal, for example, input the selection instruction on a corresponding selection item through a pull-down menu mode; the selection instruction may also be input by clicking a pop-up menu of options on the right mouse button (for example, a selection menu on the display interface shown in fig. 3A), or may be input by editing a dialog box, and the like, which is not limited herein. After the doctor inputs the selection instruction, the control terminal can capture the selection instruction input by the doctor and analyze the signal source selected by the doctor, namely the target signal source, from the selection instruction.
In an embodiment, an implementation manner of the above S104 is further provided, as shown in fig. 4, the above S104 "triggering a scanning device to scan and image a target region according to a physiological signal" includes:
s301, generating a scanning protocol according to the physiological signal setting.
In the scanning imaging process, especially in the magnetic resonance scanning process, motion artifacts are generated due to the motion of the scanning position of the patient, so that the image blur cannot be used by clinical workers, slight motion can be used for removing the artifacts through an algorithm, but when the cardio-thoracic region and the abdominal region are scanned, the spontaneous respiration or heartbeat of the human body needs to be processed in the scanning stage, physiological signal monitoring is usually performed while scanning, the peak value of respiration or electrocardio is scanned, such artifact interference is shielded from the signal source, based on this, when the control terminal acquires the physiological signal acquired by the target signal source, a scanning protocol needs to be further set according to the characteristics of the physiological signal to determine the scanning mode of the scanning device, for example, the setting of the physiological signal in the scanning mode in the display interface shown in fig. 4A includes a physiological parameter triggering mode, a signal period of the physiological signal, a physiological signal period, a pulse width, and a pulse width, Trigger interval, trigger delay, scan point (at the peak of the physiological signal in the figure), etc.
S302, sending the scanning protocol to the scanning equipment to instruct the scanning equipment to scan and image the target area according to the scanning protocol.
After the control terminal acquires the scanning protocol, the scanning protocol can be sent to the scanning equipment, and the scanning equipment can scan and image the target area in the later period according to the scanning mode indicated on the scanning protocol.
Further, when the terminal executes the step S301, the terminal specifically executes the steps of: and setting physiological parameters for triggering scanning according to the attribute information of the physiological signals to obtain a scanning protocol containing the physiological parameters.
The attribute information of the physiological signal includes the type of the physiological signal, the period of the physiological signal, the size of the acquisition window, the ratio of the acquisition window, the length of the echo chain, and the like. The physiological parameters that trigger the scan include the manner in which the scan is triggered (e.g., breathing or heartbeat), the trigger interval, the trigger delay, etc. In this embodiment, when the control terminal acquires the physiological signal, the physiological parameter for triggering scanning may be determined according to the attribute information of the physiological signal, and then the scanning protocol is generated according to the determined physiological parameter for triggering scanning.
Correspondingly, when the terminal executes the step S302 "sending the scanning protocol to the scanning device to instruct the scanning device to scan and image the target area according to the scanning protocol", the specific steps are executed:
and sending the scanning protocol to the scanning equipment to instruct the scanning equipment to scan and image the target area according to the physiological parameters triggering scanning in the scanning protocol.
The physiological parameter indicating triggering scanning is the scanning mode of the scanning device, so that after the scanning device receives the scanning protocol, the scanning device can rapidly scan and image the specific part of the patient according to the scanning mode indicated by the scanning protocol without manually scanning the protocol on the scanning device, and the efficiency of the scanning mode provided by the embodiment is extremely high.
In practical applications, the terminal may also perform an early warning, that is, after the step S103 is executed, as shown in fig. 5, the step S105 may also be executed:
s105: and outputting an early warning signal when the waveform of the acquired physiological signal is abnormal and/or the intensity of the physiological signal is smaller than a second preset intensity threshold value.
The second preset intensity threshold may be determined by the control terminal according to the scanning requirement in advance.
In practical application, due to the influence of factors such as interference and environment, a physiological signal acquired by a physiological signal source may have a signal abnormality, so that before the control terminal acquires the physiological signal and triggers the scanning device to perform scanning imaging according to the physiological signal, the waveform of the physiological signal can be detected, whether the waveform of the physiological signal is abnormal or not is determined, if the waveform of the physiological signal is abnormal, an early warning signal is output, the step of detecting the physiological signal source is returned to be executed to acquire the physiological signal again until a normal or available physiological signal is acquired, and if the waveform of the physiological signal is not abnormal, the step of triggering the scanning device to perform scanning imaging on a target area according to the physiological signal is returned to be executed. Optionally, before the control terminal acquires the physiological signal and triggers the scanning device to perform scanning imaging according to the physiological signal, the control terminal may further detect the intensity of the physiological signal, compare the intensity of the physiological signal with a second preset intensity threshold, and if the intensity of the physiological signal is not less than the second preset intensity threshold, indicate that the physiological signal is usable and is an accurate physiological signal, and in this case, return to perform the step of triggering the scanning device to perform scanning imaging on the target region according to the physiological signal; if the intensity of the physiological signal is less than the second preset intensity threshold, the physiological signal is unusable and inaccurate, and in this case, the early warning signal is output, and the step of detecting the physiological signal source is returned to execute to acquire the physiological signal again until the physiological signal not less than the second preset intensity threshold is acquired.
In summary of all the above embodiments, there is also provided a scanning method, as shown in fig. 6, the method including:
