Abstract
A multi-source radiation generator in which plural radiation sources are arranged in series includes a control unit that controls a dose of radiation emitted from each of the radiation sources depending on positions of the radiation sources, and reduces variation in a radiation dose resulting from differences in positions of the radiation sources by changing an irradiation time, an anodic current value of each of the radiation sources depending on a distance from each of the radiation sources to a subject.
Claims9
A radiation generator comprising:
- electron sources configured to emit electrons;
- radiation sources arranged in series and provided with targets configured to generate radiation when electrons emitted from the electron sources strike the targets;
- and
- a control unit configured to control a dose of radiation emitted from the radiation,
- wherein the control unit controls the dose of radiation emitted from the radiation sources based on positions of the radiation sources with respect to a focusing point of the radiation generator.

A radiation generator comprising:
- electron sources configured to emit electrons;
- radiation sources arranged in series and provided with targets configured to generate radiation when electrons emitted from the electron sources are applied thereto,
- a control unit configured to control a dose of radiation emitted from the radiation sources depending on positions of the radiation sources,
- wherein the control unit controls the dose of radiation emitted from each of the radiation sources depending on a distance between a point located at a predetermined position facing the radiation source and each radiation source.
