Problems solved by technology

[0005] Since each detector module forms a single-end support fixed cantilever beam structure, there is insufficient support at this time, and the farther the detector is from the annular support plate, the greater the radial offset, which affects the imaging accuracy.

Abstract

The invention discloses a framework structure of a nuclear medicine detector module set and belongs to the technical field of nuclear medicine imaging. The framework structure is used for fixation ofa nuclear medicine detector and an annular support plate and comprises a liquid cooling plate for an installation of a detector, a first fixing plate and a second fixing plate both fixed on two ends of the liquid cold plate and oppositely arranged, a cross beam connecting the first fixing plate and the second fixing plate, wherein the liquid cold plate, the first fixing plate, the second fixing plate and the cross beam are enclosed to form rectangular space accommodating the detector; and opposite surfaces of the first fixing plate and the second fixing plate are fixed on the annular support plate. Powerful support is provided for the detector getting far away from the annular support plate; connection stability of the framework structure and the detector module set can be enhanced; radialoffset of the detector getting far away from the annular support plate can be reduced; installation precision of the detector can be improved; and imaging quality can be increased.

Description

technical field [0001] The invention relates to the technical field of nuclear medicine imaging, in particular to a frame structure of a nuclear medicine detector module. Background technique [0002] In the field of medical imaging technology, PET (Positron Emission Tomography) system is an important medical imaging system, and its core device is a detector. The detectors in the PET system judge the annihilation position and intensity of radionuclides in the human body based on the detected coincidence events, and reconstruct the distribution of radioisotopes in human organs through preset algorithms, and then reconstruct images that can be used for diagnosis . The above calculation process needs to be performed based on a certain detector physical model, and the spatial position of each detector in the detector physical model is a theoretical position. In actual use, the PET system includes a detector ring formed by a plurality of detectors distributed in a ring shape, s...
