INTERVENTION APPLICATIONS OF REAL TIME X-RAY COMPUTED TOMOGRAPHY

摘要

Techniques for positioning a probe in a living subject include inserting the probe into the subject and then exposing the subject to a first X-ray beam. First scan data that consists of a plurality of volume elements that each indicates X-ray absorption at a corresponding volume inside the living subject is received based on computer tomography and the first X-ray beam. A first image based on the first scan data and a position of the probe is presented in real time, shorter than 0.5 seconds after exposing the living subject to the first X-ray beam. These techniques allow the probe to be operated in real time relative to features of an anatomy of the subject, which are evident in the first image.
