Embodiment 1

[0031] (Example 1) see figure 1 , the radiotherapy positioning device of the present embodiment comprises CT machine 1, CT bed 2, radiotherapy machine 3, radiotherapy couch 4, computer 6 and a time-of-flight camera 5, CT machine 1, CT couch 2, radiotherapy machine 3, radiotherapy couch 4 , time-of-flight camera 5 are all connected with computer 6 .

[0032] CT machine 1 is the medical facility "computerized tomography camera" used for scanning in the hospital. CT machine 1 scans a certain part of the human body at a certain thickness through the X-ray beam. Absorbed by tissues, part of the rays pass through the human body and are received by the detection organs to generate signals. Because the density of various tissues of the human body is different, the penetration ability of X-rays is different, so the rays received by the detector are different. After converting the received ray signals with differences into digital information, the computer will process them and output...

Abstract

The invention discloses a radiotherapy positioning device comprising a CT (Computer Tomography) machine, a CT bed, a radiotherapy machine, a radiotherapy bed, a time flying camera and a computer connected with the members. The time flying camera is fixedly arranged right at the rear upper part of the radiotherapy bed and is opposite to the radiotherapy machine. The time flying camera is a real-time 3D mapping camera based on the time flying principle and can realize real-time three-dimensional imaging on the patients. In a computer, tumor position information in the CT three-dimensional imageobtained by scanning the CT machine is guided into the real-time three-dimensional image captured by the time flying camera so as to drive the radiotherapy bed to move by the computer according to the position of the tumor in the real-time three-dimensional image and perform accurate and located radiotherapy by the radiotherapy machine. By adopting the single-lens camera, the positioning device can realize real-time three-dimensional imaging on the patients, and has rapid positioning speed, good instantaneity and lower cost.

Description

technical field [0001] The invention relates to a precise positioning device and a positioning method for radiotherapy. Background technique [0002] Radiation therapy is radiation therapy, which refers to the use of rays to eliminate lesions, and radiation such as X-rays, γ-rays, and electron rays to irradiate cancer tissues. Due to the biological effects of radiation, it can kill cancer tissues in the largest amount, destroy cancer tissues, and make them shrink. As an important means of treating malignant tumors, radiotherapy can produce good results for many cancers. [0003] However, during radiation therapy, the radiation will also affect the normal tissue in the treatment area, causing damage to normal cell tissue and causing corresponding side effects. [0004] Therefore, in the course of radiotherapy, it is necessary to accurately locate the patient's tumor location, so as to minimize the damage of radiotherapy to normal tissues. At present, precise positioning dev...
