摘要： According to one embodiment, Switching units are configured to switch the intensity of X-rays to be generated by an anode. An X-ray controller controls the switching units to switch the intensity of the X-rays to be generated by the anode, and controls a rotor control power generator to rotate the anode. When a value approximately equal to an integer multiple of an X-ray intensity switching period designated by a user coincides with the rotor rotation period, the X-ray controller controls the rotor control power generator to shift the thermoelectron collision ranges of the anode in the first turn from thermoelectron collision ranges in the second turn.

摘要： In a radiographic image capturing apparatus for capturing radiographic images by controlling a radiation generator and a detection device for converting an intensity distribution of radiation generated by the radiation generator into image information, the exposure conditions of each frame in dynamic image radiography are determined so as to set a total irradiation dose of radiation for the dynamic image radiography to be equal to or smaller than an irradiation dose required for a single static image radiography on the basis of the exposure condition of the dynamic image radiography. The dynamic image radiography is executed by capturing the radiographic image of each frame under the determined exposure conditions.

摘要： In a radiation emitting device, particularly in a radiation therapy device, isodose curves are adjusted both by a moveable plate that is controlled during irradiation and by varying the dose rate of the radiation beam during irradiation. By superimposing the effects of moving the plate and varying the dose rate of the radiation beam, it is possible to vary the isodose curve in the object of irradiation, so that a wide range of variation in the possible isodose curves is obtained. If the plate is moved at a constant speed, e.g. various wedge-shaped isodose curves can be easily achieved.
