Classification: CPC G | IPC G

Claim 0:
1. An X-ray CT apparatus comprising:
a scanner configured to perform first imaging and second imaging, the first imaging being performed for a detailed examination, and the second imaging being performed prior to the first imaging at a lower dose than the first imaging; and
processing circuitry configured to
generate a three-dimensional volume image from data acquired in the second imaging,
generate a two-dimensional virtual projection image from the three-dimensional volume image,
extract auxiliary information from the three-dimensional volume image,
infer a disease by using the two-dimensional virtual projection image and the auxiliary information,
determine an imaging condition of the first imaging based on information on the disease having been inferred, and
control the scanner in such a manner that the scanner performs the first imaging based on the determined imaging condition.
