Description

Radiotherapy monitoring system and method
Technical Field

Background
Radiotherapy is a treatment for malignant tumors or tissues that is performed using radiation such as α, β, γ rays generated by radioactive isotopes and various types of x-rays.
At present, radiotherapy is still an important means for treating malignant tumors and some benign diseases, before treatment, a patient is usually positioned by using a laser lamp, a technician needs to observe whether a cross mark of the laser lamp is aligned with a cross line on the body surface of the patient in a treatment room, and when the cross mark is not aligned, the technician adjusts a treatment bed. After the positioning is completed, the patient is sent into the radiotherapy equipment to perform the simulation treatment in the state that the radioactive source of the radiotherapy equipment is closed, and each target point is aligned with the isocenter respectively. Although this procedure technician is faced with equipment that is not delivering the treatment beam in the treatment room, it is likely to be exposed to smaller amounts of radiation (e.g., gamma knife equipment), and since the technician is often faced with multiple patients, career accumulation of these small amounts of radiation is not negligible; in the accelerator scenario where there is no additional radiation at all, there is also some effect on the efficiency of the work to and from the device operating room and treatment room.
In addition, during follow-up treatment, due to the existence of high-dose treatment-level radiation, the technician cannot continuously observe whether collision occurs or not at a close distance, and currently collision simulation is mainly used for avoiding collision during follow-up treatment. This approach assumes that one collision simulation can represent the following possible multiple treatments and does not avoid the patient from colliding during the subsequent treatment due to the larger body or the change of the outer contour posture. In the treatment process, the existing monitoring can only qualitatively observe the operation of the equipment, namely, the observation angle or visual angle of the monitoring equipment can not always correctly reflect whether collision (to be) occurs or not, and a monitor can easily misjudge whether collision occurs or not.

under different viewing angles, when the collision-prone areas or collision-prone points in the images of the part to be monitored are collided, the monitoring result is that the part to be monitored is collided;
and under any view angle, when the collision-prone area or the collision-prone point in the image of the part to be monitored does not collide, the monitoring result indicates that the part to be monitored does not collide.
14. The radiation therapy monitoring method of claim 13,
detecting that the crumple zone or crumple point crashes, comprising:
and when the distance between each easy collision area or each easy collision point is smaller than a preset threshold value, determining that the easy collision areas or the easy collision points collide.
