X-ray ct imaging method and x-ray ct device

摘要

To reduce an amount of artifacts of a tomographic image of a heart in an X-ray CT apparatus for generating a tomographic image by reconstructing projection data acquired by scanning a predetermined slice of a subject by providing the X-ray CT apparatus with a detecting means for detecting a static cardiac time phase with a small amount of motion artifacts in a predetermined portion of the subject based on heartbeat information acquired in association with the projection data, and an image reconstructing means for generating the tomographic image by reconstructing projection data corresponding to the static cardiac time phase detected by the detecting means.
