PROBLEM TO BE SOLVED: To achieve reduction in radiation exposure during imaging taking a relatively long imaging time for both purposes of blood vessel form observation and cardiac muscle perfusion, for example.SOLUTION: The X-ray diagnosis apparatus is provided with an X-ray source 2 to generate pulse X-rays, an X-ray detector 5 to detect the X-ray beam which has penetrated a sample, an image operation memory part 10 to generate an image based on the output of the X-ray detector, and a system control part 8 to control the X-ray beam for repeatedly generating the pulse X-rays, and varying the generation cycle of pulse X-rays within an imaging period.COPYRIGHT: (C)2008,JPO&INPIT【課題】撮像時間が比較的長時間にわたる例えば血管形態観察目的と心筋灌流目的を兼ねた撮像において、被曝低減を実現すること。【解決手段】X線診断装置は、パルスX線を発生するX線源2と、被検体を透過したX線を検出するX線検出器5と、X線検出器の出力に基づいて画像を発生する画像演算記憶部10と、パルスX線を撮像期間内に繰り返し発生させるとともにパルスX線の発生周期を撮像期間内で変化させるためにX線源を制御するシステム制御部8とを具備する。【選択図】図1
