BIPLANE X-RAY IMAGING METHOD AND BIPLANE X-RAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce the effect of scattered radiation and improve a frame rate in biplane X-ray apparatus and its imaging method. SOLUTION: The biplane X-ray apparatus is provided with a plurality of imaging systems having X-ray tubes 11 and 21 and X-ray detectors 12 and 22. This imaging method using the biplane X-ray apparatus includes steps of emitting the X-ray from the X-ray tube 11 of one imaging system and collecting scattered radiation image data at high speed by the X-ray detector 22; emitting the X-ray from the X-ray tube 21 of the other imaging system and collecting image data including the scattered radiation by the X-ray detectors 12 and 22, continued to the high speed collection; differentiating the scattered radiation image data collected by the corresponding X-ray detectors from the image data including the respective scattered radiations collected by the X-ray detectors 12 and 22 of the plurality of imaging systems; and providing a desired image taken by the plurality of imaging systems.
