Abstract

The invention discloses a quality control calibration method and system for single-photon emission tomography equipment. The method comprises a step of placing a uniform surface source model with the injection of target nuclide at the front surface of a single-photon emission tomography equipment probe with a collimator, a step of collecting original data of output digital signal amplitude and time information of each independent channel, a step of obtaining a gain pre-correction coefficient according to a method of comparison a reference and correcting the output original data of each channel, a step of collecting corresponding data according to needs to complete the gain correction and energy correction calibration operations of a detected, and a step of realizing probe energy resolution and scale factor quality control calibration through introducing one or more characteristic energy peaks of a collimator or detector composition material on the basis of not increasing radiation source types. According to the method and the system, equipment probe pendulum does not need to be in a special calibration mode, special space requirements are not needed, and a technical support is provided for the fault diagnosis of remote equipment.

Description

technical field [0001] The invention relates to the technical field of nuclear medicine, in particular to a single photon emission tomography equipment quality control calibration method and system. Background technique [0002] During the long-term use of single photon emission tomography (SPECT) or gamma camera, due to the aging of electronic components, deformation of mechanical structure, and the influence of environmental temperature, the performance of SPECT will drift, and technicians need to regularly control the quality of the probe operate. Even when the performance of the device deteriorates or the image quality drops to a certain level, it is often necessary for the manufacturer or a third-party company to perform calibration operations such as channel gain correction (PMT gain), energy correction (Energy), and linearity correction (Linearity) on the device. Generally, the collimator needs to be disassembled during the routine calibration process, and the distan...
