发明名称 Data processing method for nuclear medicine, and a nuclear medicine diagnostic apparatus
摘要 A PET apparatus and a processing method according in this invention carry out arithmetic processes in parallel, in steps S4 (forward projection) and S5 (back projection), for every LOR, on list data (created from event data obtained by detecting gamma rays), and can therefore be applied to other arithmetic mechanisms and have versatility. Since parallel processing is carried out on the list data and the parallel processing is carried out in each of steps S4 (forward projection) and S5 (back projection), a competition for memory can be prevented to realize an improvement in speed. As a result, high versatility and an improvement in speed of the calculations can be attained.

主权项 1. A data processing method for nuclear medicine comprising: a forward projection processing step for obtaining forward projection processed data by carrying out, in parallel for every LOR, forward projection calculations of list data created from event data obtained by detecting radiation; and a back projection processing step for carrying out back projection calculations of the forward projection processed data or the list data, wherein an image space comprises a plurality of sections and each section is divided into a plurality of areas, and wherein the back projection calculations are performed in parallel for every area.
