s102: and acquiring the posture characteristic information of the object to be scanned.
In one embodiment, the morphological feature information of the object to be scanned may be obtained 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 the scanning room, the processor or the controller can acquire the posture 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. Wherein, the non-contact acquisition unit can be one or more of infrared sensor, radar sensor, laser sensor and camera. Further, the camera may be a 3D camera or a plurality of 2D cameras. In one embodiment, the posture characteristic information of the object to be scanned may include height, body type and the like.
When the processor or the controller acquires the posture characteristic information of the object to be scanned, the processor or the controller can synchronously guide the object to be scanned to be positioned in the target area of the scanning bed. Specifically, the processor or controller may prompt the object to be scanned to perform a relevant preparation action through voice and/or video synchronization. For example, when the object to be scanned performs MR (Nuclear Magnetic Resonance) scanning, the processor or the controller may prompt the object to be scanned to complete preparation actions related to wearing various receiving coils and the like through voice and/or video synchronization. Specifically, the processor or the controller may perform voice prompt through a speaker, and the processor or the controller may perform video prompt through an image player. Wherein, the loudspeaker can be arranged on any wall of the scanning room, and the loudspeaker can also be embedded in the medical equipment. The image player or the projector can also be arranged on the wall surface of the scanning room or embedded in the medical equipment, and only the image player or the projector is required to be ensured to project various positioning demonstration images to a ceiling or a display screen which is convenient for a to-be-scanned object to watch.
After the object to be scanned completes the relevant 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 in the target area of the scanning bed through voice or video (namely completing the actions of getting on the bed, lying down and the like). The whole process from the time when the object to be scanned enters the scanning room to the time when the object to be scanned is located in the target area of the scanning bed is automatically completed without human intervention. In one embodiment, adjusting the scanning bed to the proper position by the medical device refers to: 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 finish actions such as getting on the bed and lying down.
In one embodiment, the non-contact acquisition unit may be installed on the top of the scanning room or directly above the scanning bed, as long as it is ensured that the posture 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 be located at the target area of the scanning bed refers to: the object to be scanned is guided to lie down on the scanning bed through voice or video, and the region of the object to be scanned lying down on the scanning bed is not limited here. I.e. as long as it is ensured that the object to be scanned lies down on 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, preset scanning pose information may be determined by the processor or controller according to the posture feature information. Specifically, the processor or the controller may determine a current scanning protocol parameter of the object to be scanned according to the posture characteristic information. And then converting the scanning protocol parameters into preset scanning pose information according to a preset algorithm. The preset algorithm can adopt a traditional algorithm, and only the processor or the controller is required to convert the scanning protocol parameters into preset scanning pose information according to the preset algorithm.
S104: and establishing a posture model based on the posture characteristic information, and acquiring the current posture information of the object to be scanned.
In one embodiment, a posture model may be built by a processor or a controller based on the posture feature information, and current pose information of the object to be scanned is acquired. Specifically, the processor or the controller may obtain the posture characteristic information of the object to be scanned in real time through the non-contact acquisition unit from the time the object to be scanned enters the scanning room to the time the object to be scanned is located in the target area of the scanning bed, and establish the posture model based on the posture characteristic information. Meanwhile, after the object to be scanned is located in the target area of the scanning bed, the processor or the controller may further acquire and obtain the 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 preset scanning pose or not based on the current pose information and the posture model.
In one embodiment, it may be determined by the processor or controller whether the current pose of the object to be scanned coincides with a scan preset pose based on the current pose information and the posture model. Specifically, the processor or the controller determines preset scanning pose information of the object to be scanned according to the posture model, matches the current pose information with the preset scanning pose information, and if the matching between the current pose information and the preset scanning pose information is successful, executes step S108. If the current pose information is not successfully matched with the preset scanning pose information, the current pose of the object to be scanned needs to be subjected to fine adjustment. Specifically, the processor or the controller may guide the object to be scanned to perform fine posture adjustment through voice or video, for example, by video projecting a correct lying posture and related actions. The fine adjustment process is automatically completed in the whole process without human intervention. When the pose of the object to be scanned reaches the predetermined scanning pose after the pose fine adjustment of the object to be scanned is completed, step S108 may be executed.
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 posture of the object to be scanned reaches a scanning predetermined posture, the processor or the controller generates a scanning instruction and transmits the scanning instruction to the medical device, so that the medical device responds to the scanning instruction and starts moving the bed to the scanning 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 inhaling, exhaling, holding breath and the like through voice or video.
In one embodiment, when the medical device responds to the scanning instruction and starts moving the bed, the medical device finishes positioning the scanning position of the object to be scanned. Wherein the scanning position may be a head, a neck, an internal organ, etc. of the person. For example, assuming that the scanning position of the object to be scanned is a head, the processor or the controller has already positioned the head at the position of the scanning bed when determining that the posture of the object to be scanned reaches a scanning predetermined posture. 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 designated scanning position, the full-name is automatically completed, and a technician is not required to assist in scanning and positioning, so that the potential safety hazard can be reduced, and the labor cost is reduced. Meanwhile, because manual participation is avoided, the error of manual operation is reduced, and the scanning efficiency is further improved.
In one embodiment, the medical device may be one or more of a Computed Tomography (CT) device, a Magnetic Resonance Imaging (MRI) device, an X-ray device, a Positron Emission Computed Tomography (PET) device, and an ultrasound detection device.
By adopting the method, a technician can be prevented from directly contacting the objects to be scanned, the potential safety hazard is reduced, the labor cost is reduced, meanwhile, the whole process is free from manual participation, and the errors of manual operation are reduced, so that the inspection efficiency is improved.
Referring to fig. 2, in an embodiment, the step of obtaining the posture characteristic information of the object to be scanned includes:
s202: acquiring the posture characteristic information of the object to be scanned through a non-contact acquisition unit, and synchronously guiding the object to be scanned 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 posture 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 be located in the target area of the scanning bed through sound information and/or video image information while acquiring the posture characteristic information of the object to be scanned through the 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 guides the object to be scanned to be located in the target area of the scanning bed through a loudspeaker, an image player or a projector. The specific guidance method can be described with reference to the above embodiments, and is not described herein again.
In one embodiment, preset scanning pose information may be determined by the processor or controller according to the posture feature information. Specifically, the processor or the controller may determine a current scanning protocol parameter of the object to be scanned according to the posture characteristic information. And then converting the scanning protocol parameters into preset scanning pose information according to a preset algorithm. The preset algorithm may adopt a conventional algorithm.
In one embodiment, the processor or the controller may also determine the preset scanning pose information based on a set big data algorithm according to the posture characteristic information and big data posture characteristic information. Specifically, the processor or the controller may determine the current scanning protocol parameter of the object to be scanned according to the posture characteristic information and the big data posture characteristic information. And then converting the scanning protocol parameters into preset scanning pose information.
And the big data posture characteristic information can be stored in a cloud server. When the system is used, the processor or the controller can directly acquire the big data posture characteristic information from the cloud server. The big data posture characteristic information may be: data of a plurality of scan subjects for which scanning has been completed. In one embodiment, the big data setting algorithm may adopt a traditional big data calculation algorithm, as long as the algorithm is ensured to be able to determine the preset scanning pose information according to the posture characteristic information and the big data posture characteristic information.
In one embodiment, the step of acquiring the posture characteristic information of the object to be scanned by the non-contact acquisition unit and synchronously guiding the object to be scanned to be located in the target area of the scanning bed by sound information and/or video image information comprises: and acquiring the posture characteristic information of the object to be scanned through a non-contact acquisition unit, and synchronously guiding the object to be scanned to finish preparation according to preset actions through the sound information and/or the video image information. And after the preparation action is finished, adjusting the scanning bed through the medical equipment and guiding the object to be scanned to be positioned in the target area of the scanning bed.
In one embodiment, the object to be scanned may be guided by the sound information and/or the video image information synchronously through a processor or a controller to complete preparation according to a preset action. In one embodiment, the preset action may be wearing various receiving coils, or taking off clothes. For example, when the preset action is to wear various receiving coils, the processor or the controller may obtain the actual wearing manner of the object to be scanned in real time through the non-contact acquisition unit, compare the actual wearing manner with the preset wearing manner, 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 manner to complete correct wearing.
After the preparation action is completed, 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 in a target area of the scanning bed through voice or video (namely, the actions of getting on the bed, lying down and the like are completed). In one embodiment, adjusting the scanning bed to the proper position by the medical device refers to: the scanning bed can be descended or ascended to a proper position according to the information of the height, the age and the like of the object to be scanned, so that the object to be scanned finishes the actions of 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 to 50cm away from the ground by the medical equipment, so that the object to be scanned can complete the actions of getting on the bed and lying down.
Referring to fig. 3, in an embodiment, the step of determining whether the current pose of the object to be scanned conforms to a preset scanning pose based on the current pose information and the posture model includes:
s302: generating preset scanning pose information of the object to be scanned based on the posture model;
s304: comparing the current pose information with the preset scanning pose information, and if the current pose information is matched with the preset scanning pose information within a preset error range, determining that the current pose accords with the preset scanning pose;
s306: and if the current pose information and the preset scanning pose information are not matched within a preset error range, determining that the current pose does not accord with the preset scanning 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. 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 preset scanning pose, and executing step S108. The preset error range can be set according to actual requirements, and the preset error range is not specifically limited.
And if the current pose information and the preset scanning pose information are not matched within a preset error range, determining that the current pose does not accord with the preset scanning 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. That is, 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 executed until the current pose information is successfully matched with the preset scanning pose information.
In one embodiment, the step of generating a scan instruction to control the medical device to complete the scan when the current pose corresponds to the scan preset pose comprises: when the current pose accords with the scanning preset pose, generating a scanning instruction; and controlling the scanning bed to move through the medical equipment based on the scanning instruction, and guiding the object to be scanned to do related 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 subject to be scanned has determined the name of the medical device it needs to use and the location where it needs to be scanned before entering the scan room. For example, before entering the scanning room, the object to be scanned has already determined that it needs to be subjected to MR scanning when registering information, and the scanning position is an internal organ. After the object to be scanned enters the scanning room, the processor or the controller may automatically match the preset scanning mode according to the registration information of the object to be scanned. 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 may guide the object to be scanned to perform related actions (such as inhaling, exhaling, holding breath, etc.) 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 may control the scanning bed to move to the rearmost part (i.e., the end far away from the radiation area) through the medical device, and guide the object to be scanned to complete the getting-off action through sound information and/or video image information. Specifically, if the object to be scanned performs MR scanning, the object to be scanned may be guided to drop off the MR receiving coil through the sound information and/or the video image information, and the getting-off operation is completed. The completion of the getting-off action means that: away from the scanning bed.
