<p><P>PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus capable of easily executing a process using an image reconstruction variable corresponding to multiple different imaging conditions such as a change in X-ray tube voltage conditions in an image reconstruction process of the X-ray CT apparatus. <P>SOLUTION: This X-ray CT apparatus 100 is provided with: an imaging condition setting means capable of setting a plurality of conditions on predetermined imaging conditions; an X-ray data collection means scanning a subject and collecting X-ray projection data while rotating a rotary section having an X-ray generator and an X-ray detector using the imaging conditions; a storage section storing image reconstruction variables different according to the plurality of conditions and at least corresponding to a typical condition, incidentally to a data set collected by the X-ray projection data collection means; and an image reconstruction section including an image reconstruction process of the X-ray projection data based on the image reconstruction variable corresponding to the imaging condition used for the collection of the X-ray data including at least the conditions other than the typical condition. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
