Example Embodiment

[0013] See attached Figure 1~3 .

[0014] The non-contact measurement system for the position of chest and abdomen tumors in radiotherapy of the present invention comprises: a camera 1, an image matching contour extraction and matching card 2, and a template generation software 3. The image matching contour extraction and matching card 2 is composed of an image acquisition module, a contour extraction module, a template storage module and a contour matching module. The camera 1 is fixed on the front side of the treatment bed.

[0015] When formulating a radiotherapy plan, let the patient lie on the treatment bed and keep full inhalation for CT scanning to make a treatment plan; when the patient's treatment room is accurately positioned, the image captured by the camera is processed by the computer template generation software 3 to extract the patient's full inhalation Pneumatic state of the chest and abdomen contour line, and write the contour line as the reference contour line in...

Abstract

A method for non-contact measuring of the tumor position in chest and abdomen in order to conduct radiotherapy includes laying a patient on the bed, CT scanning to obtain the thoracico-abdominal profile, inputting it to memory module and using it as reference, laying the patient on the therapeutic bed before radiotherapy, taking its thoracico-abdominal image, inputting it to image acquiring module, extracting the thoracico-abdominal profile, comparing it with said reference, and radiotherapy if a match is found.

Description

technical field [0001] The invention relates to a method for tracking the location of thoracoabdominal tumors in radiotherapy. Background technique [0002] Because the breathing movement of the patient cannot be controlled artificially, tumors in the lungs, mediastinum, liver and other parts will move with the breathing movement, which will inevitably lead to uncertainty in the location of the tumor during radiotherapy, and the resulting error can reach 40% mm. In order to reduce the above-mentioned effects, the usual method is to increase the range of PTV, which includes too much normal tissue, thus causing unnecessary damage; or by measuring the changes in the patient's lung respiration volume to reverse the displacement of the tumor, which requires the patient to Put on a breathing mask, the equipment is complicated, expensive, and the accuracy is not high. Contents of the invention [0003] The purpose of the present invention is to measure the displacement of thora...
