In some embodiments, as shown in fig. 5C, the rotating base 200 can be tilted counterclockwise relative to the base 100 about the third rotation axis A3, wherein the counterclockwise tilting means that the rotating base 200 rotates about the third rotation axis A3 toward the side surface where the imaging assembly 300 and the treatment assembly 400 are not disposed.
In some embodiments, the rotary base 200 is tilted clockwise and/or counterclockwise about the third rotation axis A3 with respect to the base 100 in an angular range of 5 ° to 45 °, or illustratively, in an angular range of 10 ° to 30 °, or illustratively, in an angular range of 15 ° to 25 °.

In an application scenario of some embodiments, a region of a patient requiring scanning or treatment may be placed on or near the isocenter of three rotational axes to facilitate accurate and comprehensive scanning and treatment of the region.

FIG. 11 is an exemplary flow chart of a method of controlling a medical device according to some embodiments of the present description.
Some embodiments of the present description also provide a method of controlling a medical device, which may include a process 1100. As shown in fig. 11, in some embodiments, the process 1100 may be performed by a controller and/or processor and includes the steps of:
step 1110: in a first setup of the medical device 1, a target position of the imaging assembly 300 and/or the therapeutic assembly 400 is determined.
In some embodiments, the target position of the imaging assembly 300 and/or the therapy assembly 400 may be positional information that is pre-input to the controller and/or processor. The location information may, for example, be formulated by medical personnel based on the actual condition of the patient.
In some embodiments, the target location may be a point or a region within the range of motion of the imaging assembly 300 and/or the therapeutic assembly 400. In some embodiments, the target position may be determined by a coordinate system with the isocenter as the origin. In some embodiments, a three-dimensional coordinate system is established with the isocenter as an origin and the first rotation axis A1, the second rotation axis A2, and the third rotation axis A3 as coordinate axes, through which the target position is determined. In other embodiments, the target position may also be determined by a spherical coordinate system.
Step 1120: based on the target position, the imaging assembly 300 and/or the therapy assembly 400 is controlled to rotate about at least one of the axis of the spin base 200, the second axis of rotation A2, and the third axis of rotation A3.
In some embodiments, based on the target position, the controller and/or processor may determine a difference between the current position of the imaging assembly 300 and/or the treatment assembly 400 and the target position in the three-dimensional coordinate system, and based on the difference, determine that the imaging assembly 300 and/or the treatment assembly 400 needs to be rotated about several of the first rotation axis A1, the second rotation axis A2, and the third rotation axis A3, and further determine a specific rotation angle about the rotation axis.
The controller and/or processor controls the imaging assembly 300 and/or the therapy assembly 400 to rotate about the determined rotational axis and corresponding rotational angle to bring the imaging assembly 300 and/or the therapy assembly 400 to the target position.
Step 1130: after the imaging assembly 300 and/or the treatment assembly 400 reach the target position, the imaging assembly 300 is controlled to perform imaging, and/or the treatment assembly 400 is controlled to generate radiotherapeutic radiation.
In some embodiments, after the imaging assembly 300 and/or the treatment assembly 400 reach the target location, it is stated that the radiation from the imaging assembly 300 and/or the treatment assembly 400 can be directed at the focal region of the patient, at which point the controller and/or the processor controls the imaging assembly 300 to initiate the generation of radiation for imaging through the focal region and/or controls the treatment assembly 400 to initiate the generation of radiation for treatment through the focal region.
In some embodiments, in the first swing position of the medical apparatus 1, the rotating base 200 is controlled to rotate around the first rotation axis A1, so that the imaging assembly 300 on the rotating base 200 performs imaging; alternatively, the rotation base 200 is controlled to rotate about the first rotation axis A1, so that the imaging assembly 300 positioned on the rotation base 200 performs imaging, and the treatment assembly 400 positioned on the rotation base 200 generates radiotherapy radiation.
In some embodiments, the first setup of the medical device 1 refers to a posture in which the radiation emitting assembly 10 is located at the initial position.
In some embodiments, the controller may control the rotation of the rotating base 200 about the first rotation axis A1 to image the imaging assembly 300 located on the rotating base 200, and the imaging assembly 300 may send the developed image of the patient to a computer or processor for processing.
In some embodiments, the controller may control the spin base 200 to rotate about the first rotation axis A1, to image the imaging assembly 300 located on the spin base 200, and to treat the treatment assembly 400 located on the spin base 200. That is, after the imaging assembly 300 acquires the developed image of the patient, the controller may control the treatment assembly 400 to generate the radiotherapy radiation to treat the lesion based on the lesion status of the developed image.
In some embodiments, the controller may control the rotation base 200 to rotate about the first rotation axis A1 while activating the imaging assembly 300 to image and acquire a developed image of the lesion of the patient. Then, the controller controls the imaging module 300 to be turned off and controls the treatment module 400 to be turned on, and a treatment is performed based on the developed image of the lesion of the patient.
In some embodiments, the controller may control the rotation base 200 to rotate around the first rotation axis A1, activate the imaging assembly 300 to be activated for imaging, and simultaneously activate the treatment assembly 400 to be activated for generating radiotherapy radiation for treatment, so as to simultaneously scan and treat the lesion of the patient, thereby improving the treatment efficiency.
In some embodiments, in the first swing position of the medical apparatus 1, the control base 100 rotates around the second rotation axis A2, so that the therapeutic assembly 400 on the rotating base 200 generates radiotherapy radiation; alternatively, the rotating base 200 is controlled to rotate around the third rotation axis A3, so that the therapeutic assembly 400 on the rotating base 200 generates radiotherapy radiation; wherein the control base 100 is rotated about the second rotation axis A2 by an angle smaller than 90 degrees.
In some embodiments, the controller can control the base 100 to rotate about the second rotation axis A2, so that the treatment assembly 400 on the rotating base 200 generates the radiation therapy. This increases the angle of the radiation of the treatment assembly 400 to scan the left and right sides of the patient, thereby providing a more thorough treatment.
In some embodiments, the controller can control the rotation base 200 to rotate about the third rotation axis A3, so that the treatment assembly 400 located on the rotation base 200 generates the radiotherapy radiation. This may increase the angle of the radiation of the treatment assembly 400 to scan the head and foot positions of the patient, thereby providing more complete treatment.
In some embodiments, the controller may control the base 100 to rotate about the second rotation axis A2 and/or the rotation base 200 to rotate about the third rotation axis A3 while controlling the treatment assembly 400 to generate the radiotherapy radiation, so as to achieve more angle continuous treatment of the patient's lesion. In some embodiments, the controller can control the base 100 to rotate about the second rotation axis A2 and/or the spin base 200 to rotate about the third rotation axis A3, and when the treatment assembly 400 is rotated to a predetermined position, the controller can control the spin base 200 and the base 100 to stop rotating and then turn on the treatment assembly 400 to perform a positioning treatment on the lesion of the patient.
