X-ray diagnostic apparatus and control method

The X-ray diagnosis apparatus according to claim wherein

• the processing circuitry is further configured to
• set a setting range of the acquisition condition set by the feedback control,
• start acquiring of X-ray images with the set acquisition condition, and
• quire the X-ray images sequentially by rotating the arm while iteratively setting the acquisition condition within the setting range by the feedback control.

The X-ray diagnosis apparatus according to claim wherein

• the processing circuitry is configured to
• estimate the body thickness information in two acquisition directions with different thicknesses based on medical images acquired from the subject,
• estimate the acquisition condition in acquiring the X-ray images from the two acquisition directions based on the body thickness information in the two acquisition directions,
• set, based on the acquisition condition and the body thickness information in the two acquisition directions, the acquisition condition including the tube voltage, the tube current, the focal spot size and the radiation dose, the setting range of the pulse width and the pulse width at the start of acquiring the X-ray images.

An X-ray diagnosis apparatus, comprising:

• an X-ray tube configured to radiate X-rays;
• an X-ray detector configured to detect the X-rays;
• an arm holding the X-ray tube;
• and
• processing circuitry configured to
• obtain body thickness information of a subject,
• set, in accordance with a shape of the subject based on the body thickness information of the subject, a pulse width at a start of acquiring X-ray images,
• start acquiring of the X-ray images with the set pulse width, and
• acquire the X-ray images sequentially by rotating the arm while iteratively setting the pulse width by feedback control.

A control method executed by an apparatus, comprising:

• obtaining body thickness information of a subject in an acquisition direction of an X-ray image at an arm position different from an arm position at a start of acquiring X-ray images;
• setting, based on the body thickness information of the subject, acquisition condition at the start of acquiring the X-ray images;
• starting acquiring of the X-ray images with the set acquisition condition;
• and
• acquiring the X-ray images sequentially by rotating the arm while iteratively setting the acquisition condition by feedback control.
