1. An X-ray diagnosis apparatus, comprising:
processing circuitry configured to:
obtain an electrocardiographic waveform of a subject and a detection signal;
generate X-ray image data of the subject from the obtained detection signal such that the generated X-ray image data is associated with the obtained electrocardiographic waveform based on a predetermined time;
detect motion of an object rendered in each of a plurality of frames of the generated X-ray image data;
determine a first radiation timing as a cardiac phase corresponding to one of the frames exhibiting the object least moving; and
repeatedly irradiate the subject with an X-ray at the first radiation timing in each cycle of the electrocardiographic waveform of the subject.
