ABSTRACT:
An X-ray computed tomography apparatus monitors the density of a contrast medium injected into a subject with a CT value by a preparation scan so as to adjust the main scan start timing. A guidance output unit outputs guidance to the subject. A control unit compares the CT value of tomographic image data obtained by the preparation scan with the first threshold, supplies guidance data to the guidance output unit to output the guidance to the subject when the CT value has reached the first threshold. The control unit compares the CT value of the tomographic image obtained by the preparation scan with the second threshold different from the first threshold, and starts executing the main scan or preparing the execution of the main scan when the CT value has reached the second threshold.
