The processing device 100 is connected to the medical imaging device 200 and the interactive device 300 respectively.

[0069] Among them, each device in the imaging system can be located in the working area of ​​the medical imaging device 200. The working area may include: an operating room and a scanning room (also referred to as an examination room). The scanning room is an area for scanning a scanned object. The operating room is an area for doctors to operate the medical imaging device 200. The medical imaging device 200 may include a scanning device 01 and a workstation 02. The scanning device may include: a rack and a scanning bed, etc. The processing device 100 and the workstation 02 may be located in the operating room, and the scanning device 01 and the interactive device 300 may both be located in the scanning room.

[0070] Optionally, the processing device 100 may be a mobile terminal, a fixed terminal or Figure 1 The server shown in FIG. 1 may be a mobile phone, a tablet computer, a laptop computer, etc. The server may be a single server, or a server cluster composed of several servers, or a cloud computing service center.

[0071] The medical imaging device 200 may be a computed tomography (CT) device, a magnetic resonance imaging (MRI) device, an X-ray machine, etc. Figure 1 The interactive device 300 may include at least one of a display screen and a speaker, for example, a display screen and a speaker. The display screen is used to display images, and the speaker is used to play audio.

[0072] Figure 2 is a schematic diagram of another imaging system provided in an embodiment of the present application, see Figure 2 The imaging system may further include: a first image acquisition device 400, a second image acquisition device 500 and a third image acquisition device ( Figure 2 The first image acquisition device 400 , the second image acquisition device 500 , and the third image acquisition device are all connected to the processing device 100 .

[0073] Among them, the first image acquisition device 400 to the third image acquisition device are all located in the scanning room of the medical imaging device 200. The field of view of the first image acquisition device 400 can cover the scanning bed of the medical imaging device. For example, the first image acquisition device 400 can be installed above the scanning bed, such as on the top of the rack of the medical imaging device. The field of view of the second image acquisition device 500 can cover the scanning room. For example, the second image acquisition device 500 can be installed on the ceiling or wall of the scanning room. The field of view of the third image acquisition device can cover the irradiation range of the radiation source of the medical imaging device. For example, the third image acquisition device can be installed on the inner wall of the scanning hole of the rack of the medical imaging device 200, and shoot downward.

[0074] Optionally, each of the first image acquisition device 400, the second image acquisition device 500 and the third image acquisition device can be a camera or a webcam. For example, the second image acquisition device 500 and the third image acquisition device can both be RGB cameras, and the first image acquisition device can be a depth camera.

[0075] The present application embodiment provides an imaging method, which is applied to a processing device in an imaging system. The imaging system also includes: a medical imaging device and an interactive device. For example, the imaging system can be Figure 1 The imaging system shown. Figure 3 , the method comprising:

[0076] Step 101: When it is determined that a scanned object enters a scanning room of a medical imaging device, control an interactive device to display path guidance information and positioning guidance information.

[0077] The path guidance information is used to guide the scanned object to the location of the scanning bed of the medical imaging device. The positioning guidance information is used to guide the scanned object to perform a standardized positioning on the scanning bed.

[0078] Step 102: When it is determined that the posture of the scanned object is not standard, control the interactive device to continue to display positioning guidance information to guide the scanned object to adjust its posture.

[0079] After the scanned object arrives at the location of the scanning bed, it can be positioned. Although the interactive device will display positioning guidance information to guide the scanned object to position after the scanned object enters the scanning room, the scanned object's posture after positioning may still be irregular. And irregular positioning will affect the subsequent scanning process. Therefore, the processing device can detect whether the scanned object's posture after positioning is standard, and if the posture is not standard, control the interactive device to continue to display the positioning guidance information to guide the scanned object to adjust its posture.

[0080] Step 103: When the posture of the scanned object is normal, trigger the medical imaging device to scan the scanned object to obtain a medical image.

[0081] After the scan object is positioned in a standardized posture, the scanning bed can be moved so that the scanned part of the scan object is within the irradiation range of the radiation source of the medical imaging device. After that, the processing device can trigger the medical imaging device to scan the scan object to obtain a medical image.

[0082] In summary, the embodiment of the present application provides an imaging method, which can automatically control the interactive device to display path guidance information and positioning guidance information after the scanned object enters the scanning room, so as to guide the scanned object to the location of the scanning bed and guide the scanned object to position. In the case where the posture of the scanned object is not standard, the method can also control the interactive device to continue to display the positioning guidance information. In the case where the posture of the scanned object is standard, the method can automatically trigger the medical imaging device to scan the scanned object. It can be seen that the method provided by the embodiment of the present application can intelligently guide the scanned object without manual guidance. Therefore, the use of this method for imaging examinations can, on the one hand, effectively improve the intelligence of the inspection process and improve the scanning efficiency; on the other hand, it can simplify the doctor's operation and effectively improve the doctor's work experience.

[0083] Figure 4 is a flowchart of another imaging method provided by an embodiment of the present application, which can be applied to a processing device in an imaging system. The imaging system also includes: a medical imaging device, an interactive device, a first image acquisition device, a second image acquisition device, and a third image acquisition device. For example, the imaging system can be Figure 2 The imaging system shown. Figure 4 , the method may include:

[0084] Step 201: Acquire a second image through a second image acquisition device.

[0085] After the imaging system is powered on, the second image acquisition device can acquire images in real time and send the acquired second images to the processing device. Accordingly, the processing device can obtain the second image.

[0086] Step 202: If a scan object is identified from the second image, it is determined that the scan object enters a scanning room of the medical imaging device.

[0087] After the processing device obtains the second image, it can perform target detection on the second image. If the processing device recognizes the scanned object from the second image, it can be determined that the scanned object has entered the scanning room. If the processing device does not recognize the scanned object from the second image, it can be determined that the scanned object has not entered the scanning room.

[0088] Optionally, the processing device may directly perform target detection on the second image to determine whether the scanned object has entered the scanning room. Alternatively, the processing device may pre-store a target detection model. The processing device may input the second image into the target detection model to obtain a result output by the target detection model. The result includes: an object is recognized from the second image, or an object is not recognized from the second image. Then, if the result is that the object is recognized from the second image, the processing device may determine that the scanned object has entered the scanning room. If the result is that the object is not recognized from the second image, the processing device may determine that the scanned object has not entered the scanning room.

[0089] It is understandable that the processing device may obtain multiple first training data, each of which may include: a first sample image, and a result of whether an object exists in the first sample image. Then, the processing device may perform model training on the multiple first training data to obtain an object detection model.

[0090] In an embodiment of the present application, if the processing device does not detect that a scanned object has entered the scanning room for a first preset time, it can be determined that the current medical imaging device is in an idle state, and then it can be detected whether the operating time of the medical imaging device has reached the target operating time. If the processing device determines that the operating time has not reached the target operating time, the medical imaging device can be controlled to enter a dormant state. Both the first preset time and the target operating time can be pre-stored by the processing device. In this way, the energy consumption of the medical imaging device can be reduced, and the shortening of the service life of the medical imaging device can be avoided to a certain extent.

[0091] If the processing device determines that the running time reaches the target running time, a first suggestion can be sent to the prompt device, and the first suggestion is used to instruct the medical imaging device to be repaired. It can be seen that the method provided in the embodiment of the present application can repair the medical imaging device when the medical imaging device is in an idle state, which can effectively improve the utilization rate of the medical imaging device.

[0092] Optionally, the prompt device may be a workstation of the medical imaging device, or may be a mobile terminal of the doctor. After the processing device determines that the operating time of the medical imaging device has not reached the target operating time, it may directly send a sleep instruction to the medical imaging device. The medical imaging device may then enter a sleep state in response to the sleep instruction. Alternatively, the processing device may send a second suggestion to the prompt device, and the second suggestion is used to instruct the medical imaging device to enter a sleep state. After receiving the second suggestion, the prompt device may display the second suggestion for the doctor to view. Then, the doctor may touch the sleep control displayed on the workstation of the medical imaging device. Accordingly, the workstation may send a sleep instruction to the medical imaging device in response to the doctor's touch operation on the sleep control to instruct the medical imaging device to enter a sleep state.

[0093] In an embodiment of the present application, if the processing device fails to identify the scanned object from multiple consecutive frames of the second image, and the acquisition time of the multiple frames of the second image reaches a first preset time, it can be determined that no scanned object has been detected entering the scanning room for the first preset time.

[0094] Step 203: Control the interactive device to display guidance information.

[0095] After the processing device determines that a scanned object has entered the scanning room, it can control the interactive device to display guidance information. The guidance information may include: path guidance information and positioning guidance information. The path guidance information is used to guide the scanned object to the location of the scanning bed of the medical imaging device, and the positioning guidance information is used to guide the scanned object to perform a standardized positioning on the scanning bed. In addition, the guidance information may also include: basic information and precautions for the examination.

[0096] Optionally, the guidance information may include at least one of audio and video, for example, audio and video. The interactive device may display the video of the guidance information through a display screen and play the audio of the guidance information through a speaker to achieve the effect of displaying the guidance information.

[0097] It is understandable that, in the process of the scanned object going to the location of the scanning bed, the interactive device can repeatedly play the guidance information until the scanned object reaches the location of the scanning bed. For example, the processing device can detect whether the scanned object has reached the location of the scanning bed. If the processing device detects that the scanned object has not reached the location of the scanning bed, it can automatically control the interactive device to display the guidance information. Alternatively, the interactive device can also be connected to a workstation located in the operating room. The workstation has a play button, and the workstation can send a play instruction to the interactive device in response to the doctor's touch operation on the play button to instruct the interactive device to replay the guidance information.

[0098] Optionally, the play button may be a physical button. In this case, the touch operation may be a pressing operation. Alternatively, the play button may be a virtual control displayed on the workstation. In this case, the touch operation may be a touch operation.

[0099] In an embodiment of the present application, after the scanned object enters the scanning room, the processing device can also identify the behavior of the scanned object based on the continuous multi-frame second image. The behavior includes: one of: walking, standing, falling and destroying the equipment. The imaging system can also include: an alarm device connected to the processing device. After the processing device identifies that the behavior of the scanned object is abnormal, it can control the alarm device to send an alarm signal to prompt the doctor to check. The continuous multi-frame second image can be: a multi-frame image collected within a specified acquisition time. The specified acquisition time can be pre-stored by the processing device, for example, it can be 1 second (s).

[0100] Specifically, if the processing device determines that the behavior of the scanned object is a first abnormal behavior that affects the health of the scanned object, the alarm device can be controlled to send a first warning signal. If the processing device determines that the behavior of the scanned object is a second abnormal behavior that damages the medical imaging device, the alarm device can be controlled to send a second warning signal. For example, the first abnormal behavior may be that the scanned object falls to the ground, and the second abnormal behavior may be that the scanned object damages the device.

[0101] Optionally, the first warning signal and the second warning signal may both be sound signals and / or light signals. The first warning signal and the second warning signal may be the same or different. For example, the first warning signal is different from the second warning signal, so that it is convenient for doctors to distinguish between falling down and damaging equipment. For example, assuming that the first warning signal and the second warning signal are both light signals, the color and / or flashing frequency of the light of the first warning signal and the second warning signal may be different.

[0102] The processing device may pre-store a behavior recognition model. The processing device may input a plurality of consecutive frames of second images into the behavior recognition model to obtain the behavior of the scanned object output by the behavior recognition model.

[0103] It is understandable that the processing device may obtain multiple second training data, each of which may include: a second sample image and a behavior of a sample object in the second sample image. Then, the processing device may perform model training on the multiple second training data to obtain a behavior recognition model.

[0104] In the embodiment of the present application, when the behavior of the scanned object is the second abnormal behavior, the processing device may further control the interactive device to issue a first reminder message. The first reminder message is used to remind the scanned object to stop damaging the medical imaging device.

[0105] Optionally, the alarm device and the interactive device may be two independent devices. Alternatively, the alarm device is the interactive device described above. In the case where the alarm device is the interactive device, since falling down will affect the life and health of the scanned object, the falling down behavior is more serious than the behavior of destroying the device. In addition, the behavior of destroying the device is more serious than the guidance information. Therefore, the priority of the first warning signal may be higher than the priority of the second warning signal, and the priority of the second warning signal may be higher than the priority of the guidance information.

[0106] Furthermore, when two pieces of information with different priorities need to be displayed simultaneously (such as warning signals or guidance information), the processing device first controls the warning device to display the information with a higher priority. That is, during the process of the interactive device displaying the guidance information, if the processing device identifies that the behavior of the scanned object is the first abnormal behavior (or the second abnormal behavior), the first warning signal (or the second warning signal) may be issued first.

[0107] Optionally, the second warning signal may be used to indicate that the medical imaging device is not used safely. In this case, in the event of a failure of the medical imaging device, the processing device may control the alarm device to also send out the second warning signal.

[0108] Step 204: After the scanned object arrives at the location of the scanning bed, a first image of the scanned object is acquired by a first image acquisition device.

[0109] After the scanned object arrives at the location of the scanning bed, it will usually be positioned. Although the interactive device will display positioning guidance information to guide the scanned object to position after the scanned object enters the scanning room, the posture of the scanned object after positioning may still be irregular. And irregular positioning will affect the subsequent scanning process. Therefore, the processing device needs to determine whether the posture of the scanned object after positioning is standard. In addition, the processing device also needs to determine the moving distance of the scanning bed, so that after the scanning bed moves according to the moving distance, the scanning center point of the medical imaging device can be aligned with the scanning starting point of the scanning part, and determine whether the scanned object will have a risk of collision with the components of the medical imaging device. The above judgment operations and the operation of determining the moving distance must be implemented based on the image of the scanned object located on the scanning bed.

[0110] Therefore, after the scanned object arrives at the position of the scanning bed, the processing device can control the first image acquisition device to start up, so as to obtain the first image through the first image acquisition device, and then judge whether the posture of the scanned object after positioning is standard based on the first image, whether there is a risk of collision between the scanned object and the components of the medical imaging device, and determine the moving distance of the scanning bed.

[0111] In the embodiment of the present application, after the processing device identifies the scanned object from the second image, it can determine whether the detection frame of the scanned object overlaps with the detection frame of the scanning bed. If the processing device determines that the detection frame of the scanned object overlaps with the detection frame of the scanning bed, it can be determined that the scanned object has arrived at the location of the scanning bed. If the processing device determines that the detection frame of the scanned object does not overlap with the detection frame of the scanning bed, it can be determined that the scanned object has not yet arrived at the location of the scanning bed.

[0112] The detection frame of the scanned object (or scanning bed) may be the smallest external frame of the scanned object (or scanning bed). Optionally, the shape of the detection frame may be a rectangle, a polygon, an ellipse or other shapes, for example, a rectangle. The embodiment of the present application does not limit the shape of the detection frame.

[0113] It is understandable that the processing device can determine whether the detection frame of the scanned object overlaps with the detection frame of the scanning bed based on the position of the detection frame of the scanned object in the second image and the position of the detection frame of the scanning bed in the second image. The position of the detection frame of the scanned object in the second image is determined by the processing device performing target detection on the second image. The position of the detection frame of the scanning bed in the second image can be calibrated in the second image and pre-written into the processing device by the staff after completing the installation of the second image acquisition device.

[0114] Step 205: Determine a result of determining the posture of the scanned object based on the first image.

[0115] The judgment result is standard or non-standard. The posture of the scanned object may include: body position and positioning posture.

[0116] In an embodiment of the present application, the process of determining the judgment result of the body position by the processing device based on the first image may include: the processing device identifies the body position of the scanned object based on the first image. Then, the processing device detects whether the body position of the scanned object is the same as the standard body position. If the processing device determines that the body position is different from the standard body position, the judgment result of the body position of the scanned object is determined to be non-standard. If the processing device determines that the body position is the same as the standard body position, the judgment result of the body position of the scanned object is determined to be standard.

[0117] Among them, the standard body position may include: head first or feet first, and one of supine, prone, left side and right side. It can be understood that the processing device can read the inspection requirements of the scanned object from the information system based on the identification of the scanned object, and the inspection requirements may include: scanning part. Then, the processing device can obtain the standard body position corresponding to the scanning part from the pre-stored correspondence between body parts and body positions based on the inspection requirements. The standard body position meets the requirements of the scanning sequence of the scanning part. The identification of the scanned object can be used to uniquely identify the scanned object among multiple objects, for example, it can be the identity code of the scanned object.

[0118] In an embodiment of the present application, the process of determining the judgment result of the position posture of the scanned object based on the first image by the processing device may include: the processing device obtains a first position set based on the first image. The first position set includes: the position of each key point of multiple key points of the body of the scanned object. Then, the processing device determines the judgment result of the position posture of the scanned object based on the first position set and the second position set.

[0119] Among them, the second position set may be pre-acquired by the processing device, and the second position set includes: the position of each key point in the multiple key points under the standard positioning posture. The position of each key point in the first position set and the second position set may refer to: the coordinates of the key point in the physical coordinate system. The physical coordinate system is a coordinate system established in the space where the medical imaging device is located. For example, the physical coordinate system may be a scanning bed coordinate system, the origin of the scanning bed coordinate system may be a point on the scanning bed, the X-axis may be parallel to the width direction of the scanning bed, the Y-axis may be perpendicular to the bed surface of the scanning bed, and the Z-axis may be the forward and backward direction of the scanning bed. The width direction may be perpendicular to the forward and backward direction.

[0120] It is understandable that the processing device can obtain the positions of each key point of the multiple key points of the body of the reference object in the standard positioning posture, and determine the positions of the multiple key points as the positions of the multiple key points of the scanned object in the standard positioning posture, thereby obtaining the second position set. Wherein, the body shape of the reference object is similar to the body shape of the scanned object.

[0121] In the embodiment of the present application, the processing device may directly determine the judgment result of the positioning posture of the scanned object based on the first position set and the second position set. Alternatively, the processing device may first obtain at least two target key points related to the positioning posture from multiple key points of the scanned object, and then determine the judgment result of the positioning posture of the scanned object based on the positions of each target key point in the first position set and the second position set. Among them, the at least two target key points can be determined based on the scanning part of the scanned object.

[0122] Since the processing device can filter out the target key point from multiple key points and determine the positioning posture of the scanned object based on the position of the target key point in the first position set and the second position set, the efficiency of determining the positioning posture can be improved, and the computing resources of the processing device can be effectively saved on the premise of accurately determining the positioning posture.

[0123] In an embodiment of the present application, the process in which the processing device determines the judgment result of the positioning posture of the scanned object based on the position of each target key point in the first position set and the second position set may include: for each target key point of at least two target key points, the processing device determines the moving distance of the target key point based on the position of the target key point in the first position set and the position of the target key point in the second position set. Then, the processing device detects whether the moving distance of the target key point is within a distance range. If the processing device determines that the moving distances of each target key point are all within the distance range, it can be determined that the judgment result of the positioning posture of the scanned object is standard. If the processing device determines that the moving distance of at least one target key point is outside the distance range, it can be determined that the judgment result of the positioning posture of the scanned object is non-standard. Among them, the distance range can be pre-stored by the processing device.

[0124] Optionally, the moving distance may be a Euclidean distance. The process of the processing device acquiring at least two target key points from a plurality of key points may include: the processing device pre-stores a correspondence between reference key points and body parts. The processing device is capable of determining the reference key point corresponding to the scanned part in the correspondence as the target key point. For example, assuming that the imaging examination is a lung examination and the scanned part is the chest, the at least two target key points may include: a shoulder joint, an elbow joint, a neck, and a fingertip.

[0125] In the embodiment of the present application, taking the first image acquisition device as a camera as an example, the process of the processing device acquiring the first position set based on the first image is described:

[0126] The processing device first determines the position (i.e., coordinates) of each key point of the multiple key points of the body of the scanned object in the camera coordinate system based on the first image. Then, for each key point, the processing device can obtain the position of the key point in the physical coordinate system based on the position of the key point in the camera coordinate system and the conversion relationship between the camera coordinate system and the physical coordinate system described above. The conversion relationship can be determined by the staff through calibration after completing the installation of the first image acquisition device and pre-written into the processing device.

[0127] The above embodiment is an example of how the processing device determines whether the positioning posture is standard by taking the moving distance of each target key point as an example. It can be understood that for lung examination, the processing device can also determine whether the positioning posture of the scanned object is standard in the following ways:

[0128] The processing device can normalize the first position set and the second position set. Then, the processing device can determine the first auxiliary distance from the elbow joint to the ipsilateral shoulder joint of the scanned object based on the normalized first position set; and determine the second auxiliary distance from the elbow joint to the ipsilateral shoulder joint based on the normalized second position set. In addition, the processing device can also determine the angle between the first vector from the shoulder joint to the elbow joint and the second vector from the shoulder joint to the neck based on the normalized first position set. Afterwards, if the processing device determines that the difference between the first auxiliary distance and the second auxiliary distance is within the difference range, and the angle is within the angle range, the positioning posture specification of the scanned object can be determined. Wherein, both the difference range and the angle range can be pre-stored by the processing device.

[0129] Step 206: When it is determined that the posture of the scanned object is not standard, control the interactive device to continue to display the positioning guidance information to guide the scanned object to adjust the posture.

[0130] When determining that the body position and / or positioning posture of the scanned object is not standard, the processing device can control the interactive device to continue to display the positioning guidance information to guide the scanned object to adjust the posture so that the adjusted posture is a standard posture.

[0131] It is understandable that when the processing device determines that the posture of the scanned object is not standard, it can first control the interactive device to send a second reminder message to remind the scanned object that the posture is not standard, and then control the interactive device to display the positioning guidance information and the precautions during the positioning process.

[0132] According to the description of steps 204 to 206 above, after the scanned object is located on the scanning bed, the processing device can monitor the body position and positioning posture of the scanned object through the first image acquisition device, and automatically determine whether the body position and positioning posture are standard, and automatically guide the scanned object to reposition when the body position and / or positioning posture is not standard. Since there is no need for manual observation and guidance, on the one hand, the intelligence level of the imaging system is effectively improved; on the other hand, it simplifies the doctor's operation, improves the doctor's work experience, and can reduce the risk of cross infection between doctors and patients.

[0133] Step 207: Based on the first image, if it is determined that there is a risk of collision between the scanned object and the medical imaging device, control the interactive device to issue a third reminder message.

[0134] The third reminder information is used to remind that there is a risk of collision between the scanned object and the component and that repositioning is required.

[0135] In an embodiment of the present application, the processing device can obtain the first position set mentioned above based on the first image. Then, the processing device can determine the distance between the auxiliary key point and the component based on the position of each auxiliary key point among the multiple key points and the position of the component of the medical imaging device in the physical coordinate system. Afterwards, if the processing device determines that the distance between at least one auxiliary key point and the component is less than the distance threshold, it can be determined that there is a risk of collision between the scanned object and the medical imaging device during the movement of the scanning bed. If the processing device determines that the distance between each auxiliary key point and the component is greater than or equal to the distance threshold, it can be determined that there is no risk of collision between the scanned object and the medical imaging device during the movement of the scanning bed. Among them, the auxiliary key point refers to: a key point located at the outermost periphery of the body among multiple key points under a standard positioning posture. The component may include: a rack of the medical imaging device.

[0136] Assuming that the component is a rack, the distance between each auxiliary key point and the rack refers to: the minimum distance between the auxiliary key point and the inner wall of the scanning hole of the rack on the target plane. The target plane may be perpendicular to the forward and backward direction of the scanning bed.

[0137] In an embodiment of the present application, when there is a risk of collision between the scanned object and the medical imaging device, the processing device may also control the alarm device to issue a sixth warning signal. Optionally, the priority of the sixth warning signal may be higher than the priority of the second warning signal. The sixth warning signal may be the same as or different from the first warning signal described above, for example, they may be the same.

[0138] Step 208: Determine the moving distance of the scanning bed based on the first image.

[0139] Before scanning the scanned object, the scanning bed carrying the scanned object needs to be moved to a suitable position so that the scanning center point of the medical imaging device is aligned with the scanning starting point of the scanned part, thereby obtaining a high-quality medical image. Based on this, the processing device can also determine the moving distance of the scanning bed based on the first image.

[0140] The moving distance may include: a horizontal moving distance and a vertical moving distance. The horizontal moving distance refers to: the distance the scanning bed moves forward and backward, and the vertical moving distance refers to: the distance the scanning bed moves upward and downward.

[0141] In an embodiment of the present application, the processing device may obtain a first position set based on the first image. Then, the processing device may obtain the position of the scanning start point of the scanning part from the first position set, and determine the moving distance of the scanning bed based on the position of the scanning start point and the scanning center position of the medical imaging device. The scanning center position refers to the position of the scanning center point of the medical imaging device in the physical coordinate system described above. The scanning center position may be pre-stored by the processing device.

[0142] Specifically, the processing device may determine a first distance between the scanning start point and the scanning center point in a first direction, and a second distance between the scanning start point and the scanning center point in a second direction based on the position of the scanning start point and the scanning center position. Then, the processing device may determine the first distance as the horizontal movement distance of the scanning bed, and determine the second plane distance as the vertical movement distance of the scanning bed. The first direction is parallel to the forward and backward direction of the scanning bed, and the second direction may be perpendicular to the forward and backward direction of the scanning bed.

[0143] It is understandable that the first image acquisition component may be a depth camera. Accordingly, the positions of the key points acquired by the processing device based on the first image acquired by the first image acquisition component may be three-dimensional coordinates. Thus, the processing device may determine the vertical movement distance of the scanning bed based on the first image.

[0144] In an embodiment of the present application, the processing device can automatically determine the scanning starting point based on the scanning part recorded in the inspection requirement, and then obtain the position of the scanning starting point based on the first position set. For example, assuming that the inspection requirement is to scan the knee joint, the scanning starting point can be located at the lower side of the knee joint, and the distance to the knee joint can be the target distance. The scanning end point can be located at the upper side of the knee joint, and the distance to the knee joint can also be the target distance.

[0145] The target distance may be pre-stored by the processing device, for example, 10 centimeters (cm). The lower side of the knee joint refers to the side of the knee joint close to the foot. The upper side of the knee joint refers to the side of the knee joint close to the chest.

[0146] Step 209: Control the movement of the scanning bed based on the moving distance.

[0147] After the processing device obtains the moving distance of the scanning bed, it can control the movement of the scanning bed based on the moving distance to drive the scanning object to move, so that the scanning starting point of the scanning part of the scanning object is aligned with the scanning center point of the medical imaging device.

[0148] According to the description of steps 208 to 209, the processing device can automatically determine the moving distance of the scanning bed according to the first image captured by the first image acquisition device, and control the movement of the scanning bed based on the moving distance. Compared with the method in which the doctor manually moves the scanning bed by observation, on the one hand, the moving efficiency and moving accuracy of the scanning bed can be improved; on the other hand, the doctor's operation can be simplified, and the doctor's work experience can be improved.

[0149] In an embodiment of the present application, the processing device can control the movement of the scanning bed based on the moving distance after the posture of the scanning object is standardized, there is no risk of collision between the scanning object and the components of the medical imaging device, and the scanning object reaches a stable state.

[0150] It is understandable that the processing device can detect whether the position offset of the scanned object is less than the offset threshold within the second preset time period. If the processing device determines that the position offset is less than the offset threshold, it can be determined that the time period for which the scanned object remains stationary reaches the second preset time period, and then it can be determined that the scanned object has reached a stable state. If the processing device determines that the position offset is greater than or equal to the offset threshold, it can be determined that the scanned object has not reached a stable state.

[0151] In an embodiment of the present application, the processing device may detect whether the position offset of the scanned object within the second preset time length is less than the offset threshold value based on multiple consecutive frames of first images within the second preset time length. Specifically, the processing device may obtain a first position set based on any frame of the multiple frames of first images to obtain a first position set corresponding to the multiple frames of first images. Thereafter, if the processing device determines that the moving distance of each key point is within a distance range based on the first position set corresponding to every two frames of first images, it can be determined that the position offset of the scanned object within the second preset time length is less than the offset threshold value. If the processing device determines that the moving distance of at least one key point is outside the distance range based on the first position set corresponding to at least two frames of first images, it can be determined that the position offset of the scanned object within the second preset time length is greater than the offset threshold value.

[0152] In an embodiment of the present application, the imaging system may further include: a gate control device, which is connected to the processing device and the door of the scanning room respectively. The processing device determines the posture specification of the scanned object, and there is no risk of collision between the scanned object and the components of the medical imaging device, and after the scanned object reaches a stable state, the gate control device may be controlled to close the door of the scanning room.

[0153] It is understandable that after the door of the scanning room is closed, if the processing device determines that there are multiple objects in the scanning room based on the second image, it can control the interactive device to issue a fourth reminder message. The fourth reminder message is used to prompt other objects except the scanned object to leave the scanning room of the medical imaging device to avoid exposure to radiation due to staying in the scanning room.

[0154] In addition, when it is determined that there are multiple objects in the scanning room, the processing device can also control the alarm device to send a fifth warning signal. The priority of the fifth warning signal can be higher than the priority of the second warning signal. For example, the fifth warning signal can be the same as or different from the first warning signal described above, for example, they can be the same.

[0155] Step 210: trigger the medical imaging device to scan the scan object.

[0156] In the embodiment of the present application, for an examination that does not require breath holding, the processing device can directly send a scanning instruction to the medical imaging device after the scanning bed has completed its movement, so as to trigger the medical imaging device to scan the scanning part of the scanned object. For an examination that requires breath holding after inhalation, such as a lung examination, the processing device can send a scanning instruction to the medical imaging device after the scanning bed has completed its movement and the scanned object has completed its breath holding.

[0157] Optionally, the imaging system may further include: a distance measuring sensor, which can collect the real-time distance from the distance measuring sensor to the scanning part. The real-time distance is a real-time radial distance. The breathing activity of the scanned object will cause the chest cavity to rise and fall, and the rise and fall of the chest cavity will cause the distance between the chest cavity and the distance measuring component to change. Therefore, by measuring the change of the distance, the breathing signal of the scanned object can be extracted, so as to determine whether the scanned object has completed breath holding after deep inhalation.

[0158] Specifically, the processing device can obtain the real-time distance from the distance measuring sensor to the scanning part through the distance measuring sensor, and detect whether the time length for which the real-time distance is maintained as the target distance reaches a first time length. The target distance is the distance between the scanning part and the distance measuring sensor when the scanning object completes breath holding after inhaling, that is, the maximum distance between the scanning part and the distance measuring sensor. If the processing device determines that the time length for which the real-time distance is maintained as the target distance reaches the first time length, it can be determined that the real-time distance remains stable, and then it can be determined that the scanning object has completed breath holding. If the processing device determines that the time length for which the real-time distance is maintained as the target distance does not reach the first time length, it can be determined that the scanning object has not completed breath holding. Among them, the first time length can be pre-stored by the processing device.

[0159] Since the distance measuring component can be used to determine whether the scanned object has completed breath holding, it is possible to accurately determine whether the scanned object has completed breath holding after inhaling, thereby ensuring that the quality of the acquired medical images is high.

[0160] It is understandable that for imaging examinations that require inhalation and breath holding, the processing device can also control the interactive device to display breath holding guidance information after the scanning bed has completed its movement. The breath holding guidance information is used to guide the scanned subject to hold the breath after inhalation and remain stable until the scan is completed, so as to meet the scanning requirements of the medical imaging device.

[0161] Optionally, the medical imaging device may automatically acquire a target scanning sequence based on the inspection requirements of the scanned object, and scan the scanned object based on the target scanning sequence. For example, the medical imaging device may pre-store a correspondence between body parts and recommended scanning sequences. The medical imaging device may determine the recommended scanning sequence corresponding to the scanning part recorded in the inspection requirements in the correspondence as the target scanning sequence. The target scanning sequence may include: tube current, tube voltage, layer thickness, etc.

[0162] In the embodiment of the present application, for an examination requiring breath holding, if the processing device determines that the scanned object has not completed breath holding after the third time period of the breath holding guidance information is displayed, the alarm device can be controlled to issue a seventh warning signal. The priority of the seventh warning signal is lower than the second warning signal described above, and higher than the priority of the guidance information.

[0163] Step 211: Capture a third image using a third image acquisition device.

[0164] During the scanning process of the scanned object, the third image acquisition device can acquire the third image and upload the third image to the processing device. Accordingly, the processing device can obtain the third image.

[0165] Step 212: Based on the third image, if it is identified that the scanned object is in an agitated state, the interactive device is controlled to issue a prompt message.

[0166] In the embodiment of the present application, the processing device may determine the current state of the scanned object based on the continuous multiple frames of the third image. If the processing device determines that the scanned object is in a stable state, the state of the scanned object may continue to be monitored until the scan is completed. If the processing device determines that the scanned object is in an agitated state, a prompt message may be displayed to prompt the scanned object to remain stable.

[0167] It is understandable that the processing device can detect whether the position of the body part of the scanned object has changed based on the continuous multiple frames of the third image. If the processing device determines that the position of any body part of the scanned object has changed based on the multiple frames of the third image, it can be determined that the scanned object is in an agitated state. If the processing device determines that the position of each body part of the scanned object has not changed based on the multiple frames of the third image, it can be determined that the scanned object is in a stable state. The position of the body part can be the coordinate of the body part in the physical coordinate system described above.

[0168] It can also be understood that after the second time period after the interactive device is controlled to display the prompt information, if the processing device determines that the scanned object is still in an agitated state, it can be determined that the prompt is invalid, and then the medical imaging device can be controlled to end the operation, and the alarm device can be controlled to send a third warning signal. Among them, the priority of the third warning signal can be higher than the priority of the second warning signal, and the third warning signal can be the same as or different from the first warning signal described above, for example, they can be the same.

[0169] Step 213: After the positioning image is obtained through scanning, a scanning field of view of the scanning part is obtained based on the position of the scanning part in the positioning image.

[0170] In an embodiment of the present application, after the medical imaging device scans and obtains a positioning image (also referred to as a positioning film), the positioning image can be sent to a processing device. After the processing device obtains the positioning image, it can perform image segmentation processing on the positioning image to obtain the position of the scanned part in the positioning image. Then, the processing device can automatically determine the scanning field of view (FOV) of the scanned part based on the position. The scanning field of view covers the scanned part. Afterwards, the processing device can send the scanning field of view to the medical imaging device so that the medical imaging device can formally scan the scanned object based on the scanning field of view.

[0171] Compared with the method in which doctors manually define the scanning field of view in the positioning image, the method in which the processing device automatically determines the scanning field of view based on the positioning image can effectively improve the efficiency of obtaining the scanning field of view and simplify the doctor's operation.

[0172] Step 214: After the medical image is scanned and obtained, if it is determined that the medical image is an unqualified image, the alarm device is controlled to send out a fourth warning signal.

[0173] In an embodiment of the present application, after the processing device obtains the medical image sent by the medical imaging device, it can detect whether the quality of the medical image meets the medical image quality control standard. If the processing device determines that the quality of the medical image meets the medical image quality control standard, that is, the medical image is a qualified image, the operation can be terminated. If the processing device determines that the quality of the medical image does not meet the medical image quality control standard, that is, the medical image is an unqualified image, the interactive device can be controlled to send a fourth warning signal. The priority of the fourth warning signal is lower than the priority of the second warning signal.

[0174] The medical image may include: a positioning image, and a scanned image obtained by performing a formal scan on the scanned object. The fourth warning signal is used to notify the doctor to view the medical image and determine whether the medical image meets the diagnosis requirements.

[0175] Optionally, for the positioning image, if the processing device determines that there are metal artifacts in the positioning image, or the positioning image does not include the scanning part of the scanned object, or it is determined based on the positioning image that the scanned object is not correctly positioned, it can be determined that the positioning image does not meet the medical image quality control standard, which may affect the medical diagnosis, and then the positioning image can be determined to be an unqualified image. For the scanned image, if the processing device determines that there are metal artifacts and / or motion artifacts in the scan, it can be determined that the scanned image does not meet the medical image quality control standard, which may affect the medical diagnosis, and then the scanned image can be determined to be an unqualified image.

[0176] Alternatively, the processing device may pre-store a quality detection model. The processing device may input the medical image into the quality detection model to obtain a quality determination result of the medical image output by the quality detection model. The quality determination result is qualified or unqualified. It is understandable that the processing device may obtain a plurality of third training data, each of which may include a sample medical image and a determination result of whether the sample medical image is qualified. Then, the processing device may perform model training on the third training data to obtain a quality detection model.

[0177] The unqualified image may or may not meet the diagnostic requirements. In response to the fourth warning signal, the doctor may view the unqualified image to determine whether the unqualified image meets the diagnostic requirements. Then, if the doctor determines that the unqualified image does not meet the diagnostic requirements, the medical imaging device may be triggered to re-perform the scanning operation.

[0178] Specifically, the workstation of the medical imaging device can display the unqualified image for the doctor to view. The workstation can also display a scanning control. After the doctor determines that the unqualified image does not meet the diagnostic requirements, the doctor can touch the scanning control. In response to the doctor's touch operation on the scanning control, the workstation can send a scanning instruction to the medical imaging device to instruct the medical imaging device to re-execute the scanning operation until a medical image of qualified quality is obtained.

[0179] In an embodiment of the present application, the processing device can store at least one frame of the first image acquired before the scanning bed moves, and can send the first image to a workstation of the medical imaging device. After acquiring a medical image (such as a positioning image or a scanning image), the workstation can align the first image with the medical image, and superimpose the aligned first image with the medical image to achieve superimposed display of the medical image and the corresponding human appearance image. In this way, the effect of virtual reconstruction can be achieved, thereby assisting doctors in preoperative planning.

[0180] Optionally, the processing device can store the first position set of the scanned object. In this way, when it is necessary to scan multiple scanned parts of the scanned object in sequence, the processing device does not need to repeatedly perform the operation of acquiring the first position set of the scanned object based on the first image, but can directly determine the moving distance of the scanning bed corresponding to the next scanned part by using the first image before the scanned object enters the bed, so as to realize the positioning of the scanned part. In this way, the scanning efficiency can be improved, and the computing resources of the processing device can be effectively saved.

[0181] Optionally, the interactive device provided in the embodiment of the present application may also support voice question and answer. Specifically, the interactive device also includes: a microphone. The interactive device can collect the voice emitted by the scanned object through the microphone, and the voice includes the questions raised by the scanned object. The interactive device can then perform voice recognition on the voice to obtain the text of the question, and then use the text as a search term to search in the knowledge base. If the interactive device retrieves the result of the question from the knowledge base, the result can be displayed. For example, the interactive device can display the text and / or image of the result, and play the audio of the result. If the interactive device does not retrieve the result of the question from the knowledge base, the interactive device can be controlled to send an eighth warning signal. The priority of the eighth warning signal is lower than the priority of the guidance information.

[0182] It is understandable that the knowledge base is pre-stored by the processing device. The knowledge base may store medical-related knowledge content; or, the knowledge base is an artificial intelligence module that can obtain medical knowledge content. The artificial intelligence module can aggregate data from public medical information sources. For example, the knowledge content may include: scanning processes of medical imaging equipment, expert consensus, scanning specifications, etc.

[0183] Taking CT scanning as an example, the inspection process of traditional imaging examination is described. The inspection process includes:

[0184] The doctor guides the scanned object to enter the scanning room and guides the scanned object to cooperate with the examination. Specifically, the doctor first interacts with the scanned object in the scanning room to prepare for the examination. The interaction includes: an introduction to the examination, and guiding the scanned object to the designated scanning position (i.e., the position of the scanning bed). After the scanned object is located on the scanning bed, the doctor can guide the scanned object to position according to the items to be examined by the scanned object, his own medical experience, and scanning specifications. For example, assuming that the imaging examination is a routine lung CT examination, the doctor can guide the scanned object to lie on the scanning bed, place the head on the headrest, and raise both arms. After that, the doctor can identify and locate the scanning range of the scanned object based on experience, and then move the scanning bed so that the laser light on the rack is aligned with the scanning starting point, and then move the scanning bed horizontally into the rack hole. For example, assuming that the imaging examination is a routine lung CT examination, the doctor can use the area from the chest inlet to three fingers above the navel as the scanning range, and the edge of the chest inlet as the scanning starting point, so as to align the laser light with the edge of the chest inlet. In addition, the doctor needs to monitor whether there is a risk of collision between the scanned object and the medical imaging equipment.

[0185] Then, the doctor can return to the operating room and manually input the scan object information and select the scan sequence for the scan part in the workstation in the operating room. Accordingly, the workstation can obtain the scan object information and the scan sequence in response to the doctor's input operation and selection operation. Assuming that the imaging examination is a lung CT examination, the workstation can select the lung scan sequence in response to the doctor's selection operation.

[0186] The CT device can then perform a localization film scan in response to the doctor's operation, generate and display the localization film. It is understandable that if the scanning part is the lungs, the doctor can also remind the scanned subject to take a deep breath and hold his breath and remain still during the localization film scan. The doctor can view the localization film and manually define the scanning field of view on the localization film. Accordingly, the CT device can respond to the doctor's operation of defining the scanning field, obtain and save the scanning field for subsequent formal scanning. Taking the imaging examination of the lung CT examination as an example, the defined scanning field can include the top of the lung to the bottom of the lung.

[0187] Afterwards, the doctor again guides the scanned subject to take a deep breath and hold his breath, remain still, and perform one or more sequence scans. During the scan, the doctor can monitor the scanned subject in real time through the observation window between the scanning room and the operating room to see if there are any abnormal conditions such as restlessness. After the sequence scan is completed, the doctor can view the image and confirm whether the image quality meets the diagnostic requirements according to the imaging examination specifications. If the doctor determines that the image quality does not meet the diagnostic requirements, the above steps can be repeated until an image that meets the requirements is obtained. After obtaining an image that meets the requirements, the doctor can return to the examination room and manually move the scanning bed outside the frame, and then guide the scanned subject to leave the examination room. At this point, the examination process ends.

[0188] It can be seen that in the entire examination process, doctors have more manual intervention and the degree of intelligence is low. Therefore, on the one hand, scanning is time-consuming and the labor cost of scanning is high; on the other hand, it is greatly affected by the subjective factors of doctors and is prone to omissions, which is not conducive to the convenience of scanning, image quality control and standardization.

[0189] The method provided in the embodiment of the present application can intelligently guide the scanned object to take position and position after the scanned object enters the scanning room, and intelligently identify the behavior of the scanned object, and issue prompts and warnings when abnormal behavior of the scanned object is identified. In addition, the method can read the examination requirements prescribed by the doctor for the scanned object based on the identification of the scanned object (such as an identity code), and automatically obtain the scanning configuration (such as the posture of the position) based on the examination requirements, and automatically set the sequence parameters (i.e., scanning technical parameters, including: tube current, layer thickness and tube voltage, etc.). After the scanned object is located on the scanning bed, the method can automatically determine the posture of the scanned object, automatically adjust the scanning bed, automatically determine whether there is a risk of collision during the movement of the scanning bed, and automatically confirm the scanning range based on the positioning image.

[0190] During the scanning process, the method can automatically monitor the state of the scanned object, and when the scanned object is in an agitated state, guide the scanned object to remain stable during the scanning to cooperate with the scanning process, thereby ensuring the stability of the scanning process. For imaging examinations that require inhalation and breath holding, the method can also detect the breathing signal of the scanned object without contact to automatically determine the time when the scanned object completes breath holding. After scanning and obtaining a medical image (such as a positioning image or a scanning image), the method can also automatically monitor the quality of the medical image. For medical images of unqualified quality, the doctor can be prompted to rescan. As a result, the impact of human judgment on image quality is reduced and the level of image quality control is improved.

[0191] It can be seen that the imaging method provided by the embodiment of the present application can cover all aspects of the imaging examination process, run through the entire scanning process, realize the comprehensive self-service, intelligent and standardized inspection process, and realize the traceability of the inspection process. In this way, on the one hand, it not only greatly improves the convenience and efficiency of image scanning, but also provides more reliable and efficient support for clinical diagnosis and treatment, thereby promoting the development of imaging diagnosis; on the other hand, it reduces the subjective intervention of doctors, improves the accuracy and consistency of scanning, realizes the homogeneity and standardization of the quality of medical images, and provides important support for the homogeneous mutual recognition of imaging examinations; on the other hand, it greatly reduces the operating burden of doctors, reduces labor costs, and improves the work experience of doctors.

[0192] It is understandable that the order of the steps of the imaging method provided in the embodiment of the present application can be adjusted appropriately, and the steps can be increased or decreased accordingly according to the situation. For example, step 204 and step 205 can be deleted according to the situation; or, step 207 to step 209 can be deleted according to the situation, and step 211 to step 214 can also be deleted according to the situation; or, step 207 and step 208 can be executed before step 205, or can be executed simultaneously. Any technician familiar with the technical field can easily think of a method of change within the technical scope disclosed in this application, which should be covered within the scope of protection of this application, so it will not be repeated.

[0193] In summary, the embodiment of the present application provides an imaging method, which can automatically control the interactive device to display path guidance information and positioning guidance information after the scanned object enters the scanning room, so as to guide the scanned object to the location of the scanning bed and guide the scanned object to position. In the case where the posture of the scanned object is not standard, the method can also control the interactive device to continue to display the positioning guidance information. In the case where the posture of the scanned object is standard, the method can automatically trigger the medical imaging device to scan the scanned object. It can be seen that the method provided by the embodiment of the present application can intelligently guide the scanned object without manual guidance. Therefore, the use of this method for imaging examinations can, on the one hand, effectively improve the intelligence of the inspection process and improve the scanning efficiency; on the other hand, it can simplify the doctor's operation and effectively improve the doctor's work experience.
