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.

摘要翻译： 根据本发明的PET装置和处理方法在步骤S4（前向投影）和S5（反投影）中对列表数据（从通过检测伽马射线获得的事件数据创建）的每个LOR进行算术处理， ，因此可以应用于其他算术机制，具有通用性。 由于在列表数据上执行并行处理，并且在步骤S4（向前投影）和S5（反投影）中的每一个中执行并行处理，因此可以防止对存储器的竞争以实现速度的提高。 因此，可以实现高通用性和计算速度的提高。

摘要： The disclosure has an object to provide a medical-data processing device that allows generation of an MIP image suitable for diagnosis. With the medical-data processing device of the disclosure, intensity of a body surface region in three-dimensional space data is adjusted. The body surface region corresponds to a body surface of a stereoscopic image of a subject. Since the intensity of the body surface region is adjusted to be decreased, the maximum intensity is selected from a portion except for the body surface region to generate the MIP image. This prevents the body surface of the subject from appearing upon generating the MIP image. Therefore, the MIP image is obtainable having excellent visibility to the inside of the subject.

摘要翻译： 本公开的目的是提供允许生成适合于诊断的MIP图像的医疗数据处理装置。 利用本公开的医疗数据处理装置，调整三维空间数据中的身体表面区域的强度。 身体表面区域对应于被检体的立体图像的身体表面。 由于体表面区域的强度被调整为降低，所以从身体表面区域以外的部分选择最大强度来生成MIP图像。 这样可以防止在产生MIP图像时对象的身体表面出现。 因此，可以获得对对象内部具有良好可见性的MIP图像。

摘要： Provided is a data processor used for imaging a plurality of subjects collectively. In the data processor, trimming is automatically performed to spatial data containing data on three-dimensional information for enhancing working efficiencies of experiments. Specifically, data on the subjects contained in the spatial data is divided into individual divisional data automatically and collectively. This eliminates necessity for individual trimming of the cross sectional images by the experimenter, resulting in significantly facilitating the latter image analysis.
