METHOD OF SETTING SCAN PARAMETER OF SHUTTLE MODE HELICAL SCAN AND X-RAY CT APPARATUS

摘要

PROBLEM TO BE SOLVED: To efficiently and intelligibly set photographing condition parameters such as the helical pitch and the noise index of shuttle mode helical scan independently for each region or internal organ.;SOLUTION: The scout image of a subject is displayed, and an operator specifies one or more ranges in the body axial direction of the scout image and sets the photographing condition parameters such as the helical pitch and the noise index of the shuttle mode helical scan independently for each range by graphical input or key input. By this invention, the photographing condition parameters such as the helical pitch and the noise index of the shuttle mode helical scan are efficiently and intelligibly set independently for each region or internal organ and photographing conditions are adjusted and optimized.;COPYRIGHT: (C)2007,JPO&INPIT
