Development of emission computed tomography in Japan

Creators

Description

Two positron emission computed tomography (PCT) devices developed in Japan are described. One is for head and the other for wholebody. The devices show fairly quantitative images with slight modifications of the existing algorithms because they were developed based on filtered back-projection. The PCT device seems to be better than the single photon emission computed tomography (SPECT) since it provides adequade compensation for photon attenuation in patients. (M.A.C.)

Abstract (Portuguese)

Descrevem-se dois aparelhos de tomografia computadorizada com emissao positron (PCT) desenvolvidos no Japao, sendo um para a cabeca e o outro para todo o corpo. Os aparelhos apresentam imagens quantitativas razoaveis com pequenas modificacoes dos algoritmos pois foram desenvolvidos com bases em 'filtered back-projection'. O aparelho de PCT parece ser melhor que o de tomografia computadorizada com emissao simples de fotons, ja que fornece compensacao adequada para a atenuacao de fotons em pacientes. (M.A.C.)
