단일광자방출 전산화단층촬영상에서 재구성 필터에 의한 정량화 오차에 관한 연구 = A Study on the Quantification Error due to the Reconstruction Filters in Single Photon Emission Computed Tomography(SPECT)

다국어 초록 (Multilingual Abstract)

As the computerized methods and equipments In nuclear medicine imaging increases, quantitative information is needed on the single photon emission computed tomographic Images as well as on the conventional nuclear medicine images. In this paper, the authors investigated the effect of several clinician - friendly reconstrution filters on the resultant transverse slices of backprojected Profiles of radioisotope distribution from the Quantitative point of view, and reduced the filter parameters such as cutoff frequency and order of filter which are neces mary to minimize the quantification error using computer-generated phantoms.
