发明名称 X-ray diagnostic apparatus, X-ray diagnostic method and stent for X-ray diagnosis
摘要 According to one embodiment, an X-ray diagnostic apparatus includes a data acquiring unit and a data processing unit. The data acquiring unit acquires X-ray projection data corresponding to plural directions from an object in which a stent having markers has been inserted by exposing X-rays to the object from the plural directions. The data processing unit obtains a spatial position corresponding to at least one marker out of the markers based on first three dimensional image data generated by first image reconstruction processing of the X-ray projection data to generate second three dimensional image data by second image reconstruction processing of the X-ray projection data with a correction using a shift amount obtained based on the X-ray projection data and projected data of the one marker on a projected plane of the X-ray projection data.

主权项 1. An X-ray diagnostic apparatus, comprising: a data acquiring unit, including an X-ray tube and an X-ray detector, configured to acquire X-ray projection data from an object, in which a stent having markers has been inserted, using the X-ray detector by exposing X-rays to the object from plural directions by the X-ray tube, the X-ray projection data corresponding to the plural directions; and a data processing circuit configured to obtain a spatial position corresponding to at least one marker out of the markers based on first three dimensional image data generated by first image reconstruction processing of the X-ray projection data in order to generate second three dimensional image data by second image reconstruction processing of the X-ray projection data, the second image reconstruction processing being performed with a correction using a shift amount obtained based on the X-ray projection data and projected data of the at least one marker on a projected plane of the X-ray projection data.
