Computed tomography (CT) was released in market on 1972. After CT fever, now (1988) we have 5,000 CT machines in Japan. This paper presents recent advances in CT mechanics and its clinical usefullness, compared with GE 8800 (10 years old machine) and Yokogawa's Quantex (present stage CT). Technically the improvements were not so exciting, that is, focus size has been reduced from 1.2 to 0.7mm, spatial resolution from 0.6 to 0.4mm and so on. However in clinical view point, advacements of CT in these 10 years were excellent. Detection of small lesions, possibility of differentiation in isodensity organs has been improved. Patients through-put also doubled or tripled.
