Abstract

The invention discloses a PET-CT (positron emission tomography-computed tomography) scanning device and a control method of the PET-CT scanning device. The PET-CT scanning device comprises a CT machine and a PET machine, wherein a luminous screen is arranged at a connecting part of the CT machine and the PET machine, the PET machine comprises a rebuilding computer, a coincidence circuit board and a PET control circuit board, the PET control circuit board is connected with the coincidence circuit board, the coincidence circuit board is connected with the rebuilding computer, and the PET control circuit board is connected with a driving circuit board of the luminous screen. The PET-CT scanning device and the control method of the PET-CT scanning device provided by the invention have the advantages that the body position change information of patients can be obtained through collecting light environment signal changes, so the scanning mages can be more accurately rebuilt.

Description

technical field [0001] The invention relates to a medical device and a control method thereof, in particular to a PET-CT scanning device and a control method thereof. Background technique [0002] PET-CT combines PET (positron emission tomography) and CT (computed tomography), using the same examination bed and two different reconstruction computers, and PET provides detailed molecular information such as function and metabolism of lesions , while CT provides precise anatomical positioning of lesions, one-time imaging and fusion of PET images and CT images can obtain tomographic images of all directions of the whole body, which are sensitive, accurate, specific, and precise in positioning, and can simultaneously project the pathophysiology of lesions Changes and morphological structures can significantly improve the accuracy of diagnosis and achieve the purpose of early detection of lesions and diagnosis of diseases. During PET / CT scanning, the same part of the body is not ...
