The present disclosure relates to a detector apparatus. The detector apparatus may include a detecting module, an electronics module and a cooling assembly. The detecting module may be configured to detect radiation rays emitted from a subject and generate electrical signals in response to detection of radiation rays. The electronics module may be configured to process the electrical signals generated by the detecting module. The cooling assembly may be configured to cool the detecting module and the electronics module. The cooling assembly may include a first layer and a second layer. The first layer may be thermally connected with the detecting module, and the second layer may be thermally connected with the electronics module.

System and method for PET imaging

A method for determining a correction profile of an imaging device may include obtaining first data relating to the imaging device; comparing the first data and a first condition; obtaining, based on the comparison, a first correction profile relating to the imaging device; and calibrating, based on the first correction profile, the imaging device.

System and method for PET correction

The disclosure relates to a system and method for reconstructing a PET image. The method may include: obtaining PET data relating to an object collected by a plurality of detector units; determining functional status of the plurality of detector units; generating reconstruction data based on the functional status of the respective detector units and the PET data; and reconstructing a PET image based on the reconstruction data.

Systems and methods for positron emission tomography

An imaging system based on an imaging device and/or a cooling system is provided. The imaging system may include a control module, an imaging device, and/or a cooling system. The imaging device may include a first portion and a second portion. The cooling system may include a cooling module configured to generate a cooling medium, and/or a cooling medium passage configured to spread the cooling medium.
