    • Abstract
  • The detector for whole-body-scan PETs used currently in clinical is commonly loop structure, sinogram (sinogram, also known as Sino) using the traditional method of fan beam structure if projection line is complete and rules. Along with the progress of the design concept for panel-PET, the projection of the panel-PET is Incomplete and irregular, it is of great significance to develop parallel-beam algorithm suited for panel-structure PET. Based on the structure of a breast panel-PET developed by our Lab, and base on rotating acquisition mode, an algorithm of parallel beam for breast panel-PET sinogram construction is put forward. To confirm the correctness of this algorithm, animal experiments were carried out to test and verify. Firstly, signals of animal rats were collected, then sinograms are constructed by the algorithm proposed in this paper, finally functional images of animal rats are reconstructed through those sinograms.Resultsshow that the proposed algorithm is correct indicating its feasible for panel-PET imaging reconstruction.
