Abstract

A system (500) and method for quality control of an imaging device. The method for quality control of the imaging device is implemented on an apparatus including a scanner (510) and a couch (520), the scanner (510) including multiple detection units (511), and the couch (520) being configured to support at least two radiation sources (921). The method may include obtaining an instruction regarding a couch (520) motion mode of the couch (520). The method may also include directing the couch (520) to move along an axial direction of the scanner (510) according to the instruction. The method may further include detecting, by the multiple detection units (511), target particles from the at least two radiation sources (921) under the couch (520) motion mode, wherein each two neighboring radiation sources (921) of the at least two radiation sources (921) are spaced apart, and a length of each radiation source (921) is less than a length of the scanner (510) in the axial direction of the scanner (510).

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...
