<P>PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus capable of efficiently setting the exposure dose of a subject to a predetermined value according to a reference value when changing a scanning condition. <P>SOLUTION: The X-ray CT apparatus is composed of: a calculator for calculating a predicted value of exposure dose based on the set scanning condition; a user interface for displaying a graph 611 which shows the calculated predicted value of exposure dose, and for accepting the change in the graph 611 by an operator; a setter for setting a target value of the exposure dose corresponding to the changed graph; and an adjustor for adjusting the scanning condition so that the predicted value of exposure dose calculated by the calculator approaches the set target value of exposure dose. <P>COPYRIGHT: (C)2012,JPO&INPIT |
