Positioning guidance device in radiotherapy process and application method thereof

Abstract

The invention relates to a positioning guidance device, especially a positioning guidance device in a radiotherapy process and an application method thereof. The positioning guidance device comprisesa radiotherapy accelerator, a treatment table, a control system, an enhanced irradiation lamp and an imaging device; the treatment table comprises a vertical rotating base, a table body and a torso locating apparatuses arranged on both sides of the table body, the outer side of the top of the table body is fixedly installed with a voice broadcasting apparatus for radiotherapy process guidance andbreathing guidance, and the vertical rotating base comprises a rotating mechanism, a lifting apparatus, a sliding apparatus, a first guide rail and a box-type base. The invention adjusts the positionof the treatment table to the radiotherapy accelerator through the rotating mechanism, the lifting apparatus and the sliding apparatus, generates a positioning image comparison through a first opticalvideo camera and a second optical video camera, which may effectively avoid a positioning error caused by a patient's unconscious movement, and helps to adjust the patient's breathing through the voice broadcasting apparatus, so as to reduce the influence of breathing movement on the accuracy of radiotherapy, and also reduce the patient's tension in the treatment process, and thus improve the patient's treatment efficiency.

Description

technical field [0001] The invention relates to a positioning guidance device, in particular to a positioning guidance device for a radiotherapy process and a use method thereof. Background technique [0002] With the development of society and the improvement of medical level, people's requirements for the identification, diagnosis and treatment of various diseases are gradually increasing, so it is extremely important to adopt safe and reliable diagnosis and treatment methods. Most patients with malignant tumors need radiotherapy, the ultimate goal of radiotherapy It is to minimize the dose to the surrounding normal tissues while fully administering the dose to the radiotherapy target area. In the process of radiotherapy, factors such as respiratory movement, part of the internal movement error, and setup error all affect the accuracy of the dose and the target dose during radiotherapy. The selection of the area range has a great relationship. Among them, the positioning e...

[0002] With the development of society and the improvement of medical level, people's requirements for the identification, diagnosis and treatment of various diseases are gradually increasing, so it is extremely important to adopt safe and reliable diagnosis and treatment methods. Most patients with malignant tumors need radiotherapy, the ultimate goal of radiotherapy It is to minimize the dose to the surrounding normal tissues while fully administering the dose to the radiotherapy target area. In the process of radiotherapy, factors such as respiratory movement, part of the internal movement error, and setup error all affect the accuracy of the dose and the target dose during radiotherapy. The selection of the area range has a great relationship. Among them, the positioning error is one of the important factors affecting the accuracy of radiotherapy. Because radiotherapy seriously damages the normal tissues of the human body, it is very important to use positioning guidance equipment for positioning guidance. On the other hand, many patients do not understand the operation of radiotherapy, which will lead to resistance and fear, and they cannot effectively cooperate with the treatment
