Auxiliary infrared positioning device and method based on radiation therapy

Abstract

The invention provides an auxiliary infrared positioning device and method based on radiation therapy, the auxiliary infrared positioning device comprises image acquisition devices, a control unit, adriving mechanism, a bed body, a targeting marker and a communication device; the image acquisition devices and the control unit are in data connection; the control unit is in line connection with thedriving mechanism; the driving device is disposed inside the bed body; and the control unit is in data connection with an external mobile terminal through the communication device. The auxiliary infrared positioning device and method simultaneously rely on infrared detection and the visible light fusion matching technology to determine a marked optimal body surface position, strengthen the positioning stability, reduce the damage of a radiotherapy apparatus to healthy and normal tissues, and can satisfy the requirements of the human body for directional radiotherapy.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an auxiliary infrared positioning device and method based on radiation therapy. Background technique [0002] Radiation therapy is the most common treatment for malignant tumors in the medical field today. However, radiotherapy is to irradiate the local area with radiation, so as to destroy or gradually shrink the tumor tissue, although it has a good curative effect on the tumor. However, in addition to killing tumor cells during radiotherapy, it will also kill normal cells in the human body, which will lead to impairment of the patient's immune system. [0003] In the clinical practice of tumor radiation therapy, laser positioning technology mainly uses laser positioning system to assist in radiotherapy positioning. [0004] The so-called positioning is to make the patient lie on the bed of the treatment bed, adjust the posture and position of the patient, so that ...

Problems solved by technology

[0008] There are two main disadvantages in this positioning technology: (1) using the scratch liquid to mark the laser cross line projection is usually thicker, which increases the radiotherapy error and reduces the radiotherapy accuracy; (2) modern radiotherapy Usually, the conventional segmentation technique with a treatment time of about 1-2 months is adopted. During the treatment, the crosses marked on the skin surface with scratch fluid are easily lost. Therefore, it is necessary to repeatedly trace the cross with scratch fluid, which may increase the radiotherapy error. , which increases the workload of doctors
