Referring to fig. 1, an embodiment of the present application provides a medical device scan guidance method, including:
S102: and acquiring the morphological characteristic information of the object to be scanned.
In one embodiment, the morphological feature information of the object to be scanned may be acquired by a processor or controller. In one embodiment, the object to be scanned may be a patient, a phantom, an animal, or the like. When the object to be scanned enters a scanning room, the processor or the controller can acquire the physical characteristic information of the object to be scanned in real time through the non-contact acquisition unit. Specifically, the processor or the controller is electrically connected with the non-contact acquisition unit. The non-contact acquisition unit can be one or more of an infrared sensor, a radar sensor, a laser sensor and a camera. Further, the camera may be a 3D camera or a plurality of 2D cameras. In one embodiment, the morphological feature information of the object to be scanned may include information of height, body shape, and the like.
The processor or the controller can synchronously guide the object to be scanned to be positioned in the target area of the scanning bed when acquiring the morphological characteristic information of the object to be scanned. Specifically, the processor or the controller may prompt the object to be scanned to perform related preparatory actions through voice and/or video synchronization. For example, when the object to be scanned performs MR (Nuclear Magnetic Resonance ) scanning, the processor or controller may prompt the object to be scanned to complete related preparatory actions such as wearing various receiving coils through voice and/or video synchronization. Specifically, the processor or controller may perform voice prompts through a speaker, and the processor or controller may perform video prompts through an image player. Wherein the speaker may be mounted on any wall of the scanning room, and the speaker may also be embedded in the medical device. The image player or projector can also be arranged on the wall surface of the scanning room or embedded in medical equipment, and the image player or projector can be only required to project various positioning demonstration images on a ceiling or a display screen of an object to be scanned for convenient viewing.
After the object to be scanned completes the related preparation actions, the processor or the controller can adjust the scanning bed to a proper position through the medical equipment, and simultaneously guide the object to be scanned to be positioned to a target area of the scanning bed through voice or video (namely, complete actions such as getting on and getting off, etc.). And the whole process from the object to be scanned entering the scanning room to the object to be scanned being positioned in the target area of the scanning bed is automatically completed without human intervention. In one embodiment, adjusting the scan bed to the proper position by the medical device means: the scanning bed can be lowered or lifted to a proper position according to the height of the object to be scanned, so that the object to be scanned can conveniently finish actions such as getting on the bed and lying down.
In one embodiment, the non-contact acquisition unit may be mounted on top of the scanning room or directly above the scanning bed, so long as it is ensured that the body state characteristic information of the object to be scanned can be acquired and acquired by the non-contact acquisition unit. In one embodiment, guiding the object to be scanned to the target region of the scanning bed means: the object to be scanned is guided to lie down on the scanning bed by voice or video, and the region where the object to be scanned lies down on the scanning bed is not limited. I.e. as long as the object to be scanned is ensured to lie down in the scanning bed. That is, the side of the scanning bed facing the non-contact acquisition unit is the target area of the scanning bed.
In one embodiment, the processor or controller may determine preset scan pose information from the posture feature information. Specifically, the processor or the controller may determine the current scan protocol parameters of the object to be scanned according to the morphological feature information. And then converting the scanning protocol parameters into preset scanning pose information according to a preset algorithm. The preset algorithm may be a conventional algorithm, so long as the processor or the controller converts the scan protocol parameter into preset scan pose information according to the preset algorithm.
S104: and building a body model based on the body characteristic information, and acquiring the current pose information of the object to be scanned.
In one embodiment, a posture model may be established by a processor or a controller based on the posture feature information, and current pose information of the object to be scanned is obtained. Specifically, from the object to be scanned entering a scanning room to the object to be scanned being located in the target area of the scanning bed, the processor or the controller can acquire the body state characteristic information of the object to be scanned in real time through the non-contact acquisition unit, and establish the body state model based on the body state characteristic information. Meanwhile, when the object to be scanned is located in the target region of the scanning bed, the processor or the controller may further acquire and obtain current pose information of the object to be scanned through the non-contact acquisition unit.
S106: and determining whether the current pose of the object to be scanned accords with a scanning preset pose or not based on the current pose information and the body model.
In one embodiment, it may be determined by the processor or controller whether the current pose of the object to be scanned corresponds to a scan preset pose based on the current pose information and the pose model. Specifically, the processor or the controller determines preset scanning pose information of the object to be scanned according to the body state model, matches the current pose information with the preset scanning pose information, and if the current pose information is successfully matched with the preset scanning pose information, executes step S108. If the current pose information is not successfully matched with the preset scanning pose information, the fact that the current pose of the object to be scanned is required to be finely adjusted is indicated. Specifically, the processor or the controller may guide the object to be scanned to perform fine adjustment of the posture through voice or video, for example, through video projection of the correct lying posture and related actions. The fine tuning process is completed automatically in the whole course without human intervention. When the posture of the object to be scanned is fine-tuned, the posture of the object to be scanned reaches the scanning preset posture, and step S108 may be executed at this time.
S108: and when the current pose accords with the scanning preset pose, generating a scanning instruction to control the medical equipment to complete scanning.
In one embodiment, when it is determined that the pose of the object to be scanned reaches a scan pre-determined pose, the processor or controller generates a scan instruction and sends the scan instruction to a medical device such that the medical device responds to the scan instruction and begins moving the couch to the scan center. After the scanning bed is in place, the processor or the controller can guide the object to be scanned to do relevant actions such as actions of inhaling, exhaling, shielding breath and the like through voice or video.
In one embodiment, the medical device has completed positioning the scan position of the object to be scanned when the medical device responds to the scan instruction and begins moving the couch. Wherein the scanning position may be the head, neck, internal organs, etc. of a person. For example, assuming the scanning position of the object to be scanned is a head, the processor or controller has located the head at the position of the scanning bed when it is determined that the pose of the object to be scanned reaches a scanning pre-position pose. Namely, when the processor or the controller moves the bed through the medical equipment based on the scanning instruction, the scanning position (head) can be automatically moved to the appointed scanning position, the full scale is automatically completed, and the technician is not required to assist in scanning and positioning, so that the potential safety hazard can be reduced, and the labor cost can be reduced. Meanwhile, manual participation is avoided, so that errors of manual operation are reduced, and further, the scanning efficiency is improved.
In one embodiment, the medical device may be one or more of an electronic computed tomography medical device (CT, computer Tomography), a magnetic resonance examination device (MRI, nuclear Magnetic Resonance Imaging), an X-ray device, a positron emission computed tomography display device (PET, positron Emission Computed Tomography), and an ultrasound detection device.
By adopting the method, the application can avoid direct contact between technicians and the object to be scanned, reduce the potential safety hazard and the labor cost, simultaneously avoid manual participation in the whole process, and reduce the error of manual operation, thereby improving the inspection efficiency.
Referring to fig. 2, in one embodiment, the step of obtaining the body state characteristic information of the object to be scanned includes:
s202: the physical characteristic information of the object to be scanned is acquired through a non-contact acquisition unit, and the object to be scanned is synchronously guided to be positioned in a target area of a scanning bed through sound information and/or video image information;
s204: and determining preset scanning pose information according to the body state characteristic information.
In one embodiment, the non-contact acquisition unit may be one or more of an infrared sensor, a radar sensor, a laser sensor, and a camera. In one embodiment, the processor or the controller may synchronously guide the object to be scanned to the target region of the scanning bed through sound information and/or video image information while acquiring the morphological characteristic information of the object to be scanned through a non-contact acquisition unit. Specifically, the sound information may be played through a speaker, and the video image information may be played through an image player or a projector. The processor or controller directs the object to be scanned to the scan bed target area through a speaker, image player or projector. The specific guiding manner may be described with reference to the above embodiments, and will not be described herein.
In one embodiment, the processor or controller may determine preset scan pose information from the posture feature information. Specifically, the processor or the controller may determine the current scan protocol parameters of the object to be scanned according to the morphological feature information. And then converting the scanning protocol parameters into preset scanning pose information according to a preset algorithm. Wherein, the preset algorithm can adopt a traditional algorithm.
In one embodiment, the processor or controller may also determine the preset scan pose information based on a set big data algorithm from the posture feature information and big data posture feature information. Specifically, the processor or the controller may determine the current scan protocol parameter of the object to be scanned according to the body state characteristic information and the big data body state characteristic information. And then converting the scanning protocol parameters into preset scanning pose information.
The general data attitude feature information can be stored in a cloud server. When the cloud server is used, the processor or the controller can directly acquire the big data attitude characteristic information from the cloud server. The general data body state characteristic information may be: data of a plurality of scan objects for which scanning has been completed. In one embodiment, the set big data algorithm may use a conventional big data calculation algorithm, so long as the algorithm is guaranteed to be capable of determining the preset scanning pose information according to the body state feature information and the big data body state feature information.
In one embodiment, the step of acquiring the physical characteristic information of the object to be scanned through the non-contact acquisition unit and guiding the object to be scanned to the target region of the scanning bed through sound information and/or video image information synchronously includes: and acquiring the morphological characteristic information of the object to be scanned through a non-contact acquisition unit, and synchronously guiding the object to be scanned through the sound information and/or the video image information to finish preparation according to a preset action. After the preparation action is finished, the scanning bed is adjusted through the medical equipment, and the object to be scanned is guided to be located in the target area of the scanning bed.
In one embodiment, the preparation of the object to be scanned according to the preset action can be conducted synchronously through the sound information and/or the video image information through a processor or a controller. In one embodiment, the preset action may be to wear various receiving coils, or may be to take off clothes. For example, when the preset actions are to wear various receiving coils, the processor or the controller may acquire the actual wearing mode of the object to be scanned in real time through the non-contact acquisition unit, compare the actual wearing mode with the preset wearing mode, and play the comparison process in real time through the video image, so as to prompt the object to be scanned to adjust the wearing mode, so as to complete correct wearing.
When the preparation is completed, the processor or controller can adjust the scanning bed to a proper position through the medical equipment, and simultaneously guide the object to be scanned to be positioned in the target area of the scanning bed through voice or video (namely, complete actions such as getting on and lying down). In one embodiment, adjusting the scan bed to the proper position by the medical device means: the scanning bed can be lowered or lifted to a proper position according to the height, age and other information of the object to be scanned, so that the object to be scanned can conveniently finish actions such as getting on the bed, lying down and the like. For example, if the height of the object to be scanned is 150cm and the age is 20 years, the scanning bed can be lowered to 30cm-50cm from the ground by the medical equipment, so that the object to be scanned can finish the actions of getting on and off the bed.
Referring to fig. 3, in one embodiment, the step of determining whether the current pose of the object to be scanned meets a scanning preset pose based on the current pose information and the body state model includes:
s302: generating preset scanning pose information of the object to be scanned based on the body state model;
s304: comparing the current pose information with the preset scanning pose information, and if the current pose information and the preset scanning pose information are matched within a preset error range, determining that the current pose accords with the scanning preset pose;
S306: and if the current pose information and the preset scanning pose information are not matched in a preset error range, determining that the current pose does not accord with the scanning preset pose.
In one embodiment, the processor or the controller may automatically generate preset scanning pose information of the object to be scanned according to the posture model, and compare the preset scanning pose information with the current pose information to obtain a comparison result. And if the comparison result is that the current pose information and the preset scanning pose information are matched within a preset error range, that is, the current pose information and the preset scanning pose information are successfully matched, determining that the current pose accords with the scanning preset pose, and executing step S108. The preset error range may be set according to actual requirements, and the preset error range is not specifically limited herein.
And if the current pose information and the preset scanning pose information are not matched in a preset error range, determining that the current pose does not accord with the scanning preset pose. At this time, the processor or the controller may guide the object to be scanned to complete pose adjustment through sound information and/or video image information based on the preset scanning pose information, and acquire the current pose information of the object to be scanned again through the non-contact acquisition unit. In other words, in the process of guiding the object to be scanned to perform pose adjustment through sound information and/or video image information, steps S104 to S106 may be repeatedly performed until the current pose information is successfully matched with the preset scanning pose information.
In one embodiment, the step of generating the scan instruction to control the medical device to complete the scan when the current pose matches the scan preset pose includes: generating a scanning instruction when the current pose accords with the scanning preset pose; and controlling the scanning bed to move through the medical equipment based on the scanning instruction, and simultaneously guiding the object to be scanned to do relevant actions through sound information and/or video image information according to a preset scanning mode so as to enable the medical equipment to complete scanning.
In one embodiment, the object to be scanned has determined the name of the medical device it needs to use and the location it needs to scan before entering the scan room. For example, the object to be scanned has determined that it needs to be MR scanned when registering information before entering the scan room, the scan position being the internal organ. The processor or the controller may automatically match the preset scan pattern according to registration information of the object to be scanned after the object to be scanned enters the scan room. That is, when the processor or the controller controls the scanning bed to move through the medical device based on the scanning instruction, the processor or the controller can guide the object to be scanned to perform related actions (such as inhalation, exhalation, breath-hold and the like) according to the matched preset scanning mode and through sound information and/or video image information until the scanning is completed.
After the object to be scanned is scanned, the processor or the controller can control the scanning bed to move to the tail part (namely, one end far away from the radiation area) through the medical equipment, and guide the object to be scanned to finish the action of getting out of the bed through sound information and/or video image information. Specifically, if the object to be scanned performs MR scanning, the object to be scanned can be guided to be removed from the MR receiving coil by the sound information and/or the video image information at this time, and the out-of-bed action is completed.
