X-ray diagnosis apparatus

1. An X-ray diagnosis apparatus, comprising:

a light emitting unit including a light source, wherein the light emitting unit emits light to illuminate an irradiation field of an X-ray and is provided in a console configured to accept input by an operator;

input interface circuitry configured to receive input of an X-ray condition; and

processing circuitry configured to control an emission state of the light emitting unit to change to one of at least three states, based on the X-ray condition.

2. An X-ray diagnosis apparatus, comprising:

a light emitting unit including a light source, wherein the light emitting unit emits light to illuminate an irradiation field of an X-ray and is provided in a hand switch configured to at least one of set an X-ray tube ready to generate X-rays and operate irradiation of X-rays;

input interface circuitry configured to receive input of an X-ray condition; and

processing circuitry configured to control an emission state of the light emitting unit to change to one of at least three states, based on the X-ray condition.

3. The X-ray diagnosis apparatus according to claim 2 , wherein the light emitting unit is provided in at least one of a ready switch and an irradiation switch.

4. An X-ray diagnosis apparatus, comprising:

a light emitting unit including a light source;

an X-ray detection unit housing an X-ray detector; and

processing circuitry configured to control an emission state of the light emitting unit to change to one at least three states, based on a ready state of the X-ray detection unit,

wherein the X-ray detection unit comprises a grid to avoid deterioration of a contrast of an X-ray image caused by scattered X-rays and a bucky into which the grid inserts, and the processing circuitry is further configured to judge the ready state based on whether the grid is correctly inserted into the bucky.
