It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
Fig. 1 is a schematic structural diagram of a medical imaging apparatus according to an embodiment, as shown in fig. 1, a medical imaging apparatus 100 includes a carrier 120, a sensor 140, a scanning imaging device 160, and a processor 180. The processor 180 is communicatively connected to the sensor 140 and the scanning imaging device 160, where the carrier device 120 is used to carry a subject, the sensor 140 is used to detect a respiratory signal of the subject, the scanning imaging device 160 is used to scan and image the subject on the carrier device 120, and the processor 180 is used to determine a respiratory state of the subject according to the respiratory signal detected by the sensor 140, so as to control the scanning imaging device 160 to perform a scanning imaging operation on the subject according to the respiratory state of the subject.
Specifically, the carrying device 120 may generally be configured by a carrying plate, a supporting portion, and a moving mechanism, where the carrying plate is disposed on the supporting portion, the moving mechanism may drive the carrying plate to move on the supporting portion, and the subject is fixed on the carrying plate when the subject is subjected to the scanning imaging operation, and the moving mechanism drives the carrying plate to move so as to move the subject into the scanning imaging region. After entering the scan imaging region, the sensor 140 detects a respiration signal of the subject and outputs the respiration signal to the processor 180, and the processor 180 controls the scan imaging operation of the scan imaging device 160 on the subject according to the respiration signal.
Further, the scanning imaging device 160 may include at least one of an electronic computed tomography (Computed Tomography, CT) device, an X-ray imaging device, a magnetic resonance (Magnetic Resonance, MR) device, a positron emission tomography (Positron Emission Computed Tomography, PET) device, and a radiotherapy device, where the scanning imaging device 160 may be a separate imaging device, or may be a combined imaging device such as PET-CT or PET-MR device, and if respiratory motion is generated by the subject during the scanning imaging device 160, the subject may cause motion artifacts and other effects on the imaging quality, and if the imaging quality cannot meet the requirement, the scanning imaging needs to be repeated to receive an unnecessary radiation dose. The subject's body undergoes corresponding movements or changes in breathing, and these changed signals can be detected by the sensor 140 as breathing signals to determine the subject's breathing state. For example, the pressure value and pressure distribution exerted on the carrier device may change as the subject breathes, so the sensor 140 may be a pressure sensor to detect the pressure exerted on the carrier device by the subject. The sensor 140 may be any other type of sensor that can detect a changing signal due to respiration of the subject.
After the sensor 140 detects the respiration signal of the subject, the processor 180 determines the respiration state of the subject according to the respiration signal, if the subject is in a breath hold state, the processor 180 controls the scanning imaging device 160 to perform the scanning imaging operation on the subject, and if the subject is in a normal respiration state, the processor 180 controls the scanning imaging device 160 to stop the scanning imaging operation on the subject, thereby reducing the unnecessary radiation dose received by the patient. The processor 180 may be connected to the sensor 140 and the scanning imaging device 160 in a wired or wireless manner, and the processor 180 may be disposed inside the housing of the carrier 120 or the scanning imaging device 160, or may be disposed at another location independently.

The carrying device 220 includes a carrying plate 222, a supporting portion 224, and a moving mechanism 226, wherein the carrying device 220 is used for carrying a subject, the carrying plate 222 is disposed on the supporting portion 224, and the moving mechanism 226 can drive the carrying plate 222 to move on the supporting portion 224 so as to enable the subject to enter the scanning imaging region of the scanning imaging device 260. The sensor 240 is a pressure sensor, and is fixedly disposed in the region of the carrying board 222 for carrying the subject, and the pressure sensor is used for detecting the change of the pressure applied by the subject on the carrying device in real time, so as to obtain the respiratory signal of the subject. The processor is in communication with the sensor 240 and the scanning imaging device 260 via wired or wireless means, respectively, and the processor may be disposed within the scanning imaging device 260 or may be disposed at another location independently.
Specifically, since the pressure applied to the carrier plate 222 by the human body periodically changes along with the respiratory motion when the human body breathes, the sensor 240 may be a pressure sensor, and the respiratory signal of the subject is obtained by detecting the pressure change applied to the carrier plate 222 by the subject. The pressure sensor is fixedly arranged in the region of the bearing plate 222 for bearing the subject, detects the pressure applied by the subject on the bearing plate 222 in real time, and outputs the pressure change applied by the subject on the bearing plate 222 as a breathing signal to the processor. The processor receives the respiration signal output from the pressure sensor to determine the respiration state of the subject, and thereby controls the scanning imaging operation of the scanning imaging device 260 on the subject according to the respiration state of the subject.
Further, a threshold is preset in the processor, and the threshold is the maximum value of the pressure change of the carrying board 222 in the breath holding state of the human body, and the threshold can be obtained through multiple experiments or theoretical calculation. In actual scan imaging, if the pressure change detected by the pressure sensor is smaller than the threshold, the processor determines that the subject is in a breath hold state, and controls the scan imaging device 260 to perform scan imaging operation on the subject; if the pressure change detected by the pressure sensor is greater than the threshold, the processor determines that the subject is in a normal breathing state, and controls the scanning imaging device 260 to be in a state in which the scanning imaging operation on the subject is stopped.

Specifically, the carrier plate 222 is provided with a pressure sensor 242, the pressure sensor 242 is disposed at a geometric center position of the carrier plate 222, when the subject breathes, the pressure value at the geometric center position of the carrier plate 222 changes most obviously and is most easily detected, so that the pressure sensor 242 is disposed at the position, the pressure sensor 242 detects the change of the pressure value applied by the subject on the carrier plate 222 as a breathing signal, and the breathing signal is output to the processor.
Fig. 4 is a schematic diagram of a partial structure of a medical imaging apparatus according to another embodiment, in one embodiment, as shown in fig. 4, based on the structure shown in fig. 2 and related technical matters, the sensor in this embodiment includes a plurality of pressure sensors 244, the plurality of pressure sensors 244 are disposed in a pressure area of the carrier plate 222, and the plurality of pressure sensors 244 acquire a respiratory signal of a subject by detecting a pressure distribution state and a variation of a pressure value applied by the subject on the carrier plate 222
Specifically, in order to obtain a more accurate detection effect, the number of pressure sensors provided on the carrier plate 222 may be plural, for example, 9 in the present embodiment, 9 pressure sensors 244 are provided uniformly in a pressure area on the carrier plate 222 that is in contact with the subject. The pressure sensor 244 can detect not only a change in the pressure value applied to the carrier plate 222 by the subject, but also a change in the pressure distribution state applied to the carrier plate 222 by the subject, thereby making the detection more accurate and stable.
Further, it can be understood that the number and arrangement manner of the plurality of pressure sensors 244 can be determined according to actual requirements, the more the number of the pressure sensors 244 is, the denser the arrangement is, the more accurate the detection result is, and the pressure sensors 244 can be densely arranged at the positions corresponding to the trunk of the subject in the pressure area of the carrying plate 222, and can also cover the carrying plate 222 entirely, so that the detection result is not easily affected by factors such as the height and the body type of the subject.
Fig. 5 is a schematic structural diagram of a medical imaging apparatus according to another embodiment, as shown in fig. 5, in an embodiment, a medical imaging apparatus 500 may include a carrier 520, a sensor 540, a scanning imaging device 560, and a processor (not labeled in the figure). Wherein the sensor 540 is a non-contact sensor for detecting in real time the amplitude of the subject's chest heave motion to obtain the subject's respiratory signal.
Specifically, when the human body breathes, besides the pressure applied to the bearing device changes, the chest of the human body also periodically fluctuates along with the respiration, so that the sensor can be a non-contact sensor, the non-contact sensor is arranged at a position capable of detecting the chest of the detected person, the respiratory signal of the detected person is obtained by detecting the fluctuation movement amplitude of the chest of the detected person and is output to the processor, a threshold value is preset in the processor, the threshold value is the maximum value of the fluctuation movement amplitude of the chest of the human body in a breath-hold state, if the fluctuation movement amplitude detected by the non-contact sensor is smaller than the threshold value, the processor judges that the detected person is in a breath-hold state, and the scanning imaging device 560 is controlled to be in a state of scanning imaging operation on the detected person; if the amplitude of the heave motion detected by the non-contact sensor is greater than the threshold, the processor determines that the subject is in a normal breathing state, and controls the scanning imaging device 560 to be in a state in which the scanning imaging operation on the subject is stopped. It is understood that the sensor 540 may be another sensor that can detect the chest relief motion of the subject, such as a CCD image sensor. The processor is in communication with the sensor 540 and the scanning imaging device 560, respectively, via wired or wireless means, and the processor may be disposed within the scanning imaging device 560 or may be disposed separately at other locations.
Further, in one embodiment, the non-contact sensor 540 remains relatively stationary with the subject during scanning imaging of the subject by the scanning imaging device.
Specifically, if there is a relative motion between the subject and the sensor during detection, the difficulty in recognizing the chest heave motion may increase, which may result in inaccurate detection results of the respiratory signal, so the non-contact sensor should be in a relatively stationary state with the subject, and since the carrier 520 may carry the subject to move into the scanning imaging area, the non-contact sensor 540 may be disposed on the carrier plate of the carrier 520 or on a component that may move along with the carrier plate.
Fig. 6 is a schematic diagram of a processor in one embodiment, and in one embodiment, as shown in fig. 6, the processor 180 includes a processing unit 182 and a control unit 184.

wherein the breathing state includes a breath hold state and a normal breathing state; when the breathing state is the breath hold state, the control unit 184 controls the scanning imaging device to be in a state of performing a scanning imaging operation on the subject; when the breathing state is the normal breathing state, the control unit 184 controls the scanning imaging device to be in a state in which the scanning imaging operation on the subject is stopped.
Specifically, the processing unit 182 receives a respiration signal detected by a sensor, where the respiration signal is a change signal caused by respiration motion of the subject, for example, a pressure change applied to the carrier device by the subject detected by a pressure sensor, or a fluctuation motion amplitude of the chest of the subject detected by a non-contact sensor, and the processing unit 182 converts the received signal of the pressure sensor or the non-contact sensor into a respiration state signal and sends the respiration state signal to the control unit 184. A threshold is preset in the processing unit 182, and the threshold is the maximum value of the change signal measured by the corresponding sensor when the human body holds breath. When the received respiration signal is smaller than the threshold value, the processing unit 182 generates a respiration state signal of the subject as a breath hold state, and outputs the respiration state signal to the control unit 184, and the control unit 184 controls the scanning imaging device to be in a state of performing scanning imaging operation on the subject after receiving the respiration state signal; when the received respiration signal is greater than the threshold, the processing unit 182 generates a respiration state of the subject as a normal respiration state, and outputs the respiration state signal to the control unit 184, and the control unit 184 controls the scanning imaging device to be in a state of stopping the scanning imaging operation of the subject after receiving the respiration state signal.
Fig. 7 is a schematic diagram of a processor in another embodiment, and in one embodiment, as shown in fig. 7, based on the structure shown in fig. 6 and related technical content, the processor 180 of this embodiment may further include a determining unit 186. The determination unit 186 is communicatively coupled to the processing unit 182 and the control unit 184, respectively. During a scan imaging operation of the scan imaging apparatus on the subject, the scan imaging operation is stopped due to respiration of the subject, the judging unit 186 acquires a progress of the current scan imaging operation to judge whether the scan imaging operation needs to be continued, and when the recovery of the breath-hold state of the subject is acquired from the processing unit 182, the judging unit 186 causes the control unit 184 to control the scan imaging apparatus to continue or restart the scan imaging operation.
Specifically, if the subject is breathing due to a failure to control during the scanning imaging operation, the processing unit 182 determines that the subject is in a normal breathing state, the control unit 184 controls the scanning imaging device to stop the scanning imaging operation on the subject, and when the scanning imaging operation is interrupted, the determining unit 186 obtains the progress of the current scanning imaging operation, determines whether the scanning imaging operation needs to be continued, or may be manually selected by a doctor or an operator to be continued. When the subject resumes the breath-hold state, if the scanning imaging operation needs to be continued, the judging unit 186 causes the control unit 184 to control the scanning imaging apparatus to continue the interrupted scanning imaging operation after acquiring the breath state from the processing unit 182; if the scanning imaging operation does not need to be continued, the judging unit 186 makes the control unit 184 control the scanning imaging apparatus to restart the interrupted scanning imaging operation after acquiring this breathing state from the processing unit 182.
