摘要: An X-ray diagnostic apparatus includes an X-ray imaging unit including an X-ray tube and an X-ray detecting unit to generate an X-ray image, an image generating unit generating a 3D non-blood vessel image and a 3D blood vessel image from an original 3D image generated by the X-ray diagnostic apparatus or an X-ray CT apparatus, a projection image generating unit generating a non-blood vessel projection image from the 3D non-blood vessel image and generating a blood vessel projection image from the 3D blood vessel image, a positional shift identifying unit identifying a positional shift between the X-ray image and the non-blood vessel projection image, a correcting unit correcting a positional shift of the blood vessel projection image on the basis of the positional shift, and a display unit which displays the X-ray image and the corrected blood vessel projection image.

摘要: A method for determining suitability of a device, such as a stent, for delivery through a vessel comprises the steps of generating a model representing positions of the device within the vessel, and evaluating the model to ascertain a degree of risk associated with delivery of the device through the vessel. The model may be generated based upon data describing the vessel and data describing the device. In a preferred embodiment, a color-coded image of the vessel is generated to report local vessel tortuousity relative to the device.
