Abstract

A display method in a computer tomographic apparatus is disclosed wherein a plurality of bar graphs representing the scanning schedule are generated on a display. The bar graph depicts the scanning time extending one distance and the margin time extending a second distance at a smaller width. When the scanning is taking place, signals are generated to plot over the scanning bar graph during the scanning time and plot over the margin bar graph during the margin time. The scanning time and margin time bar graphs adjoin one another and are distinguishable by the margin time extending from the scanning bar at a narrower width. This configuration allows an operator to readily determine at a glance the scanning step and progress thereof.
