医用画像情報としての核医学におけるコンピューターの利用の現状と展望

抄録

Recent technological development has yielded a variety means of medical informations. Among these informations, imaging of in vivo phenomena within the body is the most appealing and comprehensive to a clinician, and, hence, impose rather difficult task on computer processing. However, the nuclear imaging, in essence, consists of digital data, so it is quite adaptable to be processed by the computer. Since nuclear data is a series of rapid time sequence imaging, a bulk of memory capacity with high speed processing time should be requird in order to construct such type of presentation as a functional imaging, electrocardiogram-gated radionuclide angiocardiogram and etc. In addition, recent trend to reconstruct 3 D image, further capacity should be necessary in the near future. Although computer application has not yet fully affected the present diagnostic process, it might potentiate much information efficacy of the nuclear imaging as has been evidenced in the field of the cardiovascular nuclear medicine.
