摘要： An object of the present invention is to concurrently perform the horizontal movements of a cradle and a table in a desirable manner and to desirably prevent interference of the table with a gantry. A microprocessor controls and interlocks a horizontal cradle movement mechanism and a horizontal table movement mechanism. The microprocessor concurrently performs the horizontal movements of the cradle and table. If an operator tries to vary a table height or a tilt angle, the microprocessor performs arithmetic operations to check if the table will interfere with the gantry at a current scan-time position, at which the table should be located during scanning, in the varied state. If the interference is predicted, the table is pulled out of the bore of the gantry until it reaches a position at which the table will not interfere with the gantry.

摘要： The quality of an image can be improved and radiation can effectively be utilized. In an imaging area of a subject where a main scan is performed, a specific scan area setting unit sets a specific scan area where a scan is performed under a specific scan condition allowing radiation exposure dose on the subject to be low. Then, the scan condition setting unit sets a main scan condition so that the specific scan area is scanned under the specific scan condition allowing the radiation exposure dose on the subject to be low.

摘要： To enable radiation rays to be efficiently used. A scout scan parameter setting unit sets a rotation movement position to which an X-ray tube and an X-ray detector are moved so as to rotate around a subject on the basis of subject information of a subject on which a scout scan is performed at the time of performing a scout scan. At the time of starting execution of the scout scan, a rotating unit moves the X-ray tube and the X-ray detector so as to rotate around the subject to the rotation movement position which is set by the scout scan parameter setting unit. After that, a scout scan is performed in the rotation movement position.

摘要： A scale equipped with a memory display section comprises, separately from a regular display section 19 for indicating a current measured value, additionally a memory display section 20 for indicating the current measured value as a previously measured value in a series of consecutive measurements, wherein a transfer unit 22 executes such a transfer operation that the current measured value indicated in the regular display section 19 can be indicated in the memory display section 20 as the previously measured value in a series of consecutive measurements. A person in charge of measurement no more needs to take the trouble of remembering in the brain or taking notes of the previously measured values in a series of consecutive measurements, such as an incremental measurement, but the current measuring work can be carried out simply by a visual recognition.
