As used in this application and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.

Fig. 1 illustrates an exemplary flowchart of an acquisition parameter determination method of a radiation apparatus according to some embodiments of the present application. In some embodiments, the acquisition parameter determination method 100 of the radiation apparatus may be performed by an acquisition parameter determination system 200 of the radiation apparatus. As shown in fig. 1, the method 100 for determining the acquisition parameters of the radiation apparatus may include:
The photographing site may be an irradiation site where the patient needs to be subjected to image acquisition or radiotherapy. For example, the imaging location may include, but is not limited to, the abdomen, chest, brain, heart, lung, tumor location, etc. of the patient.
In some embodiments, the capture-site acquisition module 210 may acquire the capture site of the patient via AI techniques (e.g., image recognition techniques) if historical or real-time optical images or video data of the patient are combined with its diagnostic workflow. For example, the capturing part acquiring module 210 may acquire a face image or a body image of a patient through a camera, and retrieve and acquire a capturing part corresponding to the patient image from a pre-stored archive. In some embodiments, the capture area acquisition module 210 may acquire the capture area of the patient through an identification object (e.g., a card, a bracelet, etc.). For example, when a patient enters a room of the radiation apparatus, the card reader may be used for swiping a card, and the capturing part acquiring module 210 may retrieve and acquire the capturing part of the patient corresponding to the card from a pre-stored archive according to information collected by the card reader. In some embodiments, the capture site acquisition module 210 may also acquire the capture site of the patient in any reasonable manner. For example, the photographing region acquiring module 210 may acquire a photographing region of the patient input by an input device (e.g., a keyboard, a handheld terminal, etc.).
In some embodiments, the posture information of the patient may include, but is not limited to, one or more combinations of height, facial features, thickness information, body width information, skeletal joint point information, and the like of the patient. The facial features of the patient may be used to reflect the orientation of the patient (e.g., facing toward or away from the radiation generator). The thickness information may be used to reflect the distance that the radiation needs to travel through the body when the patient is photographed. For example, when the photographing part is a chest, the thickness of the photographing part may be a distance from the chest to the back of the patient. In some embodiments, the thickness information of the patient may be determined based on the height and/or weight of the patient; or may be determined based on the patient image. Body width information may be used to reflect the body width of the patient. In some embodiments, the patient's body width information may be determined based on the patient's height and/or weight; or may be determined based on the patient image. The bone joint information may include the name of the bone joint and its location. For example, the skeletal joint points may include one or more combinations of head, shoulders (e.g., left shoulder, right shoulder), elbows (e.g., left elbow, right elbow), wrists (e.g., left wrist, right wrist), hands (e.g., left hand, right hand), hips, knees (e.g., left knee, right knee), ankles (e.g., left ankle, right ankle), feet (e.g., left foot, right foot), and the like.
In some embodiments, the posture information acquisition module 220 may acquire image information of a patient based on a camera, particularly a 3D camera (which may also be referred to as a depth camera), and then acquire posture information of the patient based on the image information of the patient. Specifically, the posture information acquiring module 220 may acquire one or a combination of more of height, facial features, thickness information, body width information, skeletal joint point information, and the like of the patient using optical structured light (or optical time-of-flight method, binocular stereo vision, and the like) in the aspect ratio of the 3D camera. In some embodiments, the 3D camera may be one or more. For example, the posture information acquiring module 220 may capture multi-angle image information of the patient based on a plurality of 3D cameras to acquire more accurate posture information of the patient. In some embodiments, a 3D camera may be mounted on the radiation device so that the posture information of the patient may be acquired while the patient is in the radiation device (e.g., lying on a scanning bed). In some embodiments, the 3D camera may also be mounted in other locations. For example, a 3D camera may be installed in a device room of a radiation apparatus, so that posture information of a patient can be acquired before the patient contacts the radiation apparatus (e.g., when the patient enters the device room).
In some alternative embodiments, the posture information acquiring module 220 may acquire some or all of the posture information of the patient in other manners. For example, the posture information acquiring module 220 may acquire multi-angle images of the patient based on a plurality of cameras, thereby determining three-dimensional images of the patient in combination, and further acquiring the posture information of the patient. For another example, the posture information acquiring module 220 may acquire the posture information of the patient input by the patient or medical staff or the like based on the input device. For another example, the posture information acquiring module 220 may retrieve the posture information of the patient from the database based on the identity information of the patient.
And step 130, automatically determining acquisition parameters of the radioactive ray equipment according to the shooting part and the posture information of the patient. Specifically, the step 110 can be performed by the preset parameter determining module 230 and the acquisition parameter determining module 240.
In some embodiments, the acquisition parameters of the radiation apparatus include, but are not limited to, one or more combinations of gantry motion position, beam limiter field, stitching protocol, and exposure parameters of the high voltage generator. In some embodiments, the gantry motion position may include a position of a scanning couch, and the patient may be moved to a suitable scanning position by movement of the scanning couch while the patient is lying on the scanning couch. The beam limiter field can be reflected as the size of the opening of the beam limiter, which can determine the irradiation area of the radiation apparatus. The splicing protocol may include the number of times of shooting, the starting shooting position, the ending shooting position, the area of each shooting, the image splicing mode after shooting, and the like. The initial shooting position is a position where the radiation apparatus is first exposed in one shooting; the photographing termination position is a position where the radiation apparatus is exposed last. In some embodiments, the start shooting position and the end shooting position may be the same position when only one exposure is needed or when no position shift is needed during shooting. In some embodiments, the number of times of shooting, the area of each shooting, the image stitching manner after shooting, and the like may be obtained based on the start shooting position and the end shooting position. The exposure parameters of the high voltage generator may include one or a combination of more of tube voltage, tube current, pulse active time, and the like.
In some embodiments, the preset parameter determination module 230 may determine the preset parameters of the radiation apparatus according to the photographing site of the patient. In some embodiments, the preset parameter determination module 230 may select a corresponding preset examination protocol according to the imaging region of the patient, wherein the preset examination protocol includes preset parameters of the radiation device. For example, when the photographing part of the patient is the chest, the preset parameter determination module 230 selects a protocol for chest radiography. In some embodiments, the preset acquisition parameters of the radiation apparatus include, but are not limited to, one or more combinations of preset gantry movement positions, preset beam limiter fields, preset start shooting positions, preset end shooting positions, preset stitching protocols, and preset exposure parameters of the high voltage generator. The preset parameters of the radiographic equipment in the preset examination protocol are universal parameters for all patients, and cannot be well adapted to patients with different characteristics (such as different heights, thicknesses, body widths and the like).
In some embodiments, the acquisition parameter determination module 240 may automatically determine the acquisition parameters of the radiation device based on preset parameters of the radiation device and the posture information of the patient. For example, the acquisition parameter determination module 240 may automatically adjust preset parameters of the radiation device based on the posture information of the patient to obtain acquisition parameters of the radiation device. In one embodiment, assuming that the preset gantry motion position in the chest radiography protocol is set for a patient with a height of 1.70 m, and a patient with a height of 1.90 m, the acquisition parameter determination module 240 may adjust the gantry motion position according to the height of the patient (e.g., move 0.1 m relative to the preset gantry motion position). In yet another embodiment, when the radiographic apparatus is used to acquire an image, the patient posture information indicates that the thickness of the portion of the patient to be imaged is thick, and the acquisition parameter determination module 240 may automatically adjust (e.g., proportionally adjust) the exposure parameters of the high voltage generator (e.g., increase the tube voltage and/or the tube current) according to the thickness of the portion of the patient to be imaged. In yet another embodiment, when the image is acquired by using the radiation apparatus, the body state information of the patient indicates that the body width of the patient is large, and the acquisition parameter determining module 230 may automatically adjust the beam limiter field according to the body width of the patient (e.g., increase the opening of the beam limiter) so that the irradiation region can cover the region to be photographed.
In some embodiments, the posture information of the patient may include at least bone joint information of the patient, and the acquisition parameter determination module 240 may determine the starting photographing position and the ending photographing position according to the photographing part of the patient and the bone joint information of the patient. For example, if the photographing part of the patient is from the neck to the ankle, the acquisition parameter determination module 240 may determine the corresponding position of the neck of the patient as the initial photographing position and determine the corresponding position of the ankle of the patient as the final photographing position according to the skeletal joint information of the patient. On this basis, the acquisition parameter determination module 240 may determine a stitching protocol based on the start shot position and the end shot position. For example, since the distance from the initial shooting position (corresponding to the neck) to the final shooting position (corresponding to the ankle) may be different due to different heights of patients, the acquisition parameter determining module 240 may determine the number of times of shooting, the area of each shooting, the image stitching manner after shooting, and the like based on the initial shooting position, the final shooting position, and the distance therebetween.
And step 140, shooting the shooting part of the patient according to the acquisition parameters of the radiation equipment.
In some embodiments, in preparation for capturing, the acquisition parameter determining system 200 of the radiation apparatus may continuously acquire the posture information of the patient, and when the patient moves and the acquisition parameters of the radiation apparatus cannot meet the capturing requirement, the acquisition parameters of the radiation apparatus may be readjusted (e.g., adjusting the initial capturing position, terminating the capturing position, etc.) until the capturing requirement is met. The imaging request may be a condition that the patient needs to have in order to complete imaging by the radiation apparatus. For example, the shooting requirement may be that the part to be shot of the patient needs to be located in the optical field of the speed limiter. In some embodiments, when the patient moves such that the acquisition parameters of the radiation apparatus cannot meet the shooting requirements, the acquisition parameter determination system 200 of the radiation apparatus may return to perform step 120 to readjust the acquisition parameters of the radiation apparatus (e.g., adjusting the initial shooting position, terminating the shooting position, etc.) until the shooting requirements are met. In some embodiments, when the patient is not moving or the acquisition parameters of the radiation device still meet the shooting requirements after the patient is moving, the system 200 can shoot the shooting part of the patient according to the acquisition parameters of the radiation device.

Various modifications and changes to flowchart 100 will be apparent to those skilled in the art in light of the present disclosure. However, such modifications and variations are intended to be within the scope of the present application. For example, step 110 and step 120 in the acquisition parameter determination method of the radiation apparatus may be performed simultaneously. As another example, step 140 may be omitted, i.e. the acquisition parameter determination system 200 may be used only for determining acquisition parameters of the radiation device.

The photographing region acquiring module 210 may be used to acquire a photographing region of a patient. In some embodiments, the capture-site acquisition module 210 may acquire the capture site of the patient via AI techniques (e.g., image recognition techniques) if historical or real-time optical images or video data of the patient are combined with its diagnostic workflow. In some embodiments, the capture area acquisition module 210 may acquire the capture area of the patient through an identification object (e.g., a card, a bracelet, etc.).

The posture information acquiring module 220 may be used to acquire the posture information of the patient. In some embodiments, the posture information of the patient may include, but is not limited to, one or more combinations of height, facial features, thickness information, body width information, skeletal joint point information, and the like of the patient.
