The invention discloses a PET scanning and CT scanning linkage method and a PET / CT scanning system. The PET scanning and CT scanning linkage method comprises the steps that PET scanning operation and CT scanning operation which need to be linked are determined, wherein the PET scanning operation and the CT scanning operation which need to be linked have the same scanning range; corresponding relevant parameters are configured for the PET scanning operation and the CT scanning operation which need to be linked; if the scanning range of the PET scanning operation is changed, the CT scanning operation linked with the PET scanning operation is searched through the corresponding relevant parameters, and information of the changed scanning range is transmitted to the CT scanning operation linked with the PET scanning operation, or if the scanning range of the CT scanning operation is changed, the PET scanning operation linked with the CT scanning operation is searched through the corresponding relevant parameters, and information of the changed scanning range is transmitted to the PET scanning operation linked with the CT scanning operation. The PET / CT scanning system comprises a main control device, a PET equipment control device, a PET imaging component, a CT equipment control device and a CT imaging component. According to the PET scanning and CT scanning linkage method and the PET / CT scanning system, it is guaranteed that the PET and the CT have the same scanning range, and fusion of a PET image and a CT image in the later stage is facilitated.
Description
technical field [0001] The invention relates to the field of nuclear medicine, in particular to a PET and CT scanning linkage method and a PET / CT scanning system. Background technique [0002] Positron Emission Tomography (PET) is a relatively advanced clinical examination imaging technology in the field of nuclear medicine. It uses positron nuclide as a tracer, and the functional metabolic state of the lesion can be understood through the uptake of the tracer by the lesion site, so as to make a correct diagnosis of the disease. PET can display the pathophysiological characteristics of the lesion, making it easier to find the lesion, but the spatial resolution of PET is low. [0003] Electronic Computer X-ray Tomography Technique (CT) is another clinical examination imaging technology. It uses the different attenuation coefficients of various parts of the human body to transmit X-rays to reconstruct the tomographic image of the human body. CT can provide high-resolution a...
