PROBLEM TO BE SOLVED: To provide excellent linearity without lowering magnetic field generation efficiency. SOLUTION: Only a part of data is updated, the pertinent part of the data obtained in the past is reutilized for the remaining and an outline interventional image is prepared with relatively short scanning time and displayed on a screen. When an operator presses a 'detail button' 13a, all of the data are updated by taking relatively long scanning time and a detailed interventional image is prepared and displayed on the screen. Thus, an outline image with a real time property though image quality is degraded is obtained and the detailed image of high image quality is quickly obtained when it is needed. |
