Abstract
This invention provides an X-ray CT apparatus for performing a pre-CT which is a form of computerized tomography carried out with low doses beforehand in order to determine timing of starting a production CT which is a form of computerized tomography for acquiring images for use in diagnosis. As a radiographic mode of the pre-CT executed for a monitoring purpose, a radiographic mode suited to the purpose is selected from among three radiographic modes, i.e. a continuous radiographic mode, an intermittent radiographic mode and a combined intermittent and continuous radiographic mode. The apparatus may set, as necessary, a delay time lasting from a point of time when a pre-CT starting instruction is given to a point of time for starting the pre-CT. A coloring state of a contrast medium in a region of concern may be determined accurately at all times by executing the pre-CT. The pre-CT is started, and a switch from intermittent radiography to continuous radiography is carried out, always at appropriate times. Thus, the timing of starting the production CT may be determined properly at all times.
