Abstract

The invention provides a PET data collection method. A PET system scans molds to obtain data and comprises a detector and a scanning bed, and the detector comprises multiple detection units. The method comprises the steps that multiple molds are placed on the scanning bed at intervals, and the axial length of the molds is smaller than that of the scanning visual field of the detector; the scanningbed is controlled to drive the molds to axially move along the scanning visual field of the detector, and meanwhile a radioisotope, collected by the detection unit, of the molds is used for annihilating a reaction event.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a PET data collection method and a PET system. Background technique [0002] Positron Emission Tomography (PET) is a non-invasive nuclear medicine imaging diagnosis technology widely used clinically. It provides functional information such as metabolism of the living body by imaging the radioactive tracer injected into the living body. It plays an important role in diagnosis, efficacy evaluation, basic medical research and new drug development. [0003] PET is a technique that uses positron nuclide as a tracer to understand the functional metabolic state of the lesion through the uptake of the tracer by the lesion site, and then diagnose the disease. Specifically, the radioactive tracer drug labeled with a positron nuclide is injected into the subject, and the positron nuclide decays and emits positrons, which undergo an annihilation reaction with the negative electrons in the sub...
