Abstract

The invention relates to the technical field of medical images, and discloses a radiotherapy effect evaluation method based on PET and CT elastic registration technology, comprising the following steps: step 1: in a T1 radiotherapy pre-diagnosis stage, scanning to obtain a CT cross-sectional image and a PET image corresponding to the same part; 2, fusing the CT image and the PET image in the T1 stage, and positioning the position of a focus target region; and 3, based on the focus target information provided by the PET-CT fusion image, guiding a doctor to make a radiotherapy plan and perform radiotherapy. According to the radiotherapy effect evaluation method based on the PET and CT elastic registration technology, automatic generation of PET images corresponding to other radiotherapy stages can be realized, the shooting frequency of the PET images is reduced, the problem of high cost of multiple times of PET shooting examination is solved, and the radiation dose received by a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical images, in particular to a radiation therapy effect evaluation method based on PET and CT elastic registration technology. Background technique [0002] PET / CT does have its irreplaceable advantages in clinical medicine. The glucose metabolism of most tumors is increased. At present, an international consensus has been reached. PET / CT examinations are firstly applicable to: (1) tumor screening of high-risk groups; (2) staging and recurrence of patients who have ③ evaluation of the therapeutic effect of malignant tumors; ④ adjuvant treatment plan; ⑤ evaluation of tumor prognosis, etc. [0003] Although PET / CT has many advantages, it also has its shortcomings, which are mainly reflected in: (1) expensive, increasing the medical burden; (2) PET / CT examination has certain radiation. [0004] In order to solve the problem of high cost of multiple PET scans, we propose a radiotherapy effect evaluation...
