Abstract:
1. An X-ray CT apparatus comprising; an X-ray tube for producing an X-ray to be irradiated to an object, an X-ray detector being disposed at a position opposed to the X-ray tube so as to place the object between the X-ray tube and the X-ray detector, for detecting the X-ray that has passed through the object, a scanner rotor being equipped with the X-ray tube and the X-ray detector for rotating around the object, an operating means for inputting and setting information necessary for a scanogram imaging and a scan imaging, and for carrying out an operation, an imaging condition decision means for deciding an imaging condition upon scanning, based on scanogram projection data of the object detected by the X-ray detector, and a scan means for doing a scan under the imaging condition decided by the imaging condition decision means, the X-ray CT apparatus reconstructing a tomographic image of the object based on a transmitted X-ray dose that is scanned by the scan means and detected by the X-ray detector, wherein, the imaging condition decision means further comprising, a storage means for storing a standard imaging condition, an object three-dimensional model generating means for analyzing the scanogram projection data and generating an object three-dimensional model, a diagnostic object size setting means for setting a diagnostic object size of the object by the operating means, and
