Method of displaying the scanning schedule in a computer tomographic apparatus

A method of displaying the scanning schedule for computer tomographic apparatus comprising a scanner for scanning an object to be examined;

• a setting device for setting the scanning schedule including a margin time setting value between a previous scanning step and the next scanning step for each of a series of a plurality of scanning steps to be effected by said scanner;
• a visual display for concurrently displaying a schedule of scannings as numbers, delay times as numbers, intervals as numbers and graphic figures representing the scanning schedule;
• and a controller for causing said scanner to conduct scanning for the object according to the schedule for a series of a plurality of scanning steps set by the setting device, and displaying as graphic figures the set scanning schedule and proceeding state of the scanning schedule on said display;
• said method comprising the steps of
• displaying the individual scanning steps in the visual display as a first bar representing the length of the scanning time and a second bar having a different configuration from said first bar and added as an extension of the first bar for indicating the length of time of said margin time, with the first and second bars being disposed on said visual display opposite the corresponding step of the scanning schedule, delay time and interval;
• and
• changing in real time the composition of the first bar as the scanning proceeds until the scanning in that step is completed and then subsequently changing in real time the composition of the second bar as the margin time proceeds, whereby an operator can determine instantaneously from the number of the scanning schedule, the number of the delay, and from the number of the interval, and the composition of the first and second bars in the visual display, the steps already executed, the exact part of the exact step of the scanning schedule being executed, and the steps still to be executed.
