Abstract
An X-ray diagnosis apparatus according to an embodiment includes an X-ray tube, judging circuitry, and grid controlling circuitry. The X-ray tube is configured to radiate X-rays. The judging circuitry is configured to judge whether a voltage should be applied to a grid of the X-ray tube or not, in accordance with a radiation condition. The grid controlling circuitry is configured to apply the voltage to the grid, if the judging circuitry has determined that the voltage should be applied.
Claims8
An X-ray diagnosis apparatus, comprising:
- an X-ray tube configured to radiate X-rays, the X-ray tube including a grid;
- judging circuitry configured to judge whether a voltage should be applied to the grid or not, in accordance with a radiation condition;
- and
- grid controlling circuitry configured to, when the judging circuitry has determined that the voltage should be applied, apply the voltage to the grid,
- wherein the judging circuitry determines that the voltage should be applied when an X-ray tube voltage and an X-ray tube current serving as the radiation condition are both lower than respective threshold values that are set in advance.
An X-ray diagnosis apparatus, comprising:
- an X-ray tube configured to radiate X-rays, the X-ray tube including a grid;
- an X-ray detector configured to detect the X-rays that have passed through a patient;
- setting circuitry configured to set a radiation condition based on detection data of the X-rays detected by the X-ray detector,
- judging circuitry configured to judge whether a voltage should be applied to the arid or not, in accordance with the radiation condition set by the setting circuitry, and
- grid controlling circuitry configured to, when the judging circuitry has determined that the voltage should be applied, apply the voltage to the grid.
