Abstract

The invention relates to a non-invasive tumor locating system and a non-invasive tumor locating method. The time concept is introduced on the basis of a three-dimensional radiotherapy technology; the motion during the treatment process and the displacement error of fractionated treatment of anatomy tissue are fully considered, such as the situations at the aspects of changes of radiotherapy dose distribution and influences to the treatment plan caused by breathing peristalsis motion, daily positioning error, target region contraction and the like; and the tumor and the normal organs are monitored in real time by utilizing various kinds of advanced image devices before and during the treatment of patients, and the treatment conditions can be regulated according to the changes of the organ position, thus the radiation field follows the target region closely, and the accurate treatment is really achieved.

Description

technical field [0001] The invention relates to a non-invasive tumor positioning system and a positioning method, in particular to a non-invasive tumor positioning system and a positioning method which reduce displacement errors by positioning marker points. Background technique [0002] Tumor has increasingly become the biggest threat to people's health in modern society. With the development of science and technology, tumor treatment technology has also made great progress. Because most of the tumors are located in the body, it is still difficult to accurately locate the tumor. Since the skin on the surface of the body is easy to move, there is a relatively large error in positioning only through the skin surface. In the prior art, the external device is usually fixed on the body for positioning, but this will bring great pain to the patient. After the patient takes a CT image for tumor location, the treatment system usually formulates a treatment plan based on the locat...
