As a tomography x-ray fluoroscopic image

摘要

A medical imaging system is provided for diagnostic and interventional procedures. The system includes a C-arm having an x-ray source and a receptor for obtaining fluoroscopic images of a patient. The C-arm is moved through an image acquisition path (A, B), along which at least first and second images are obtained. An acquisition module obtains multiple 2-D fluoroscopic images at desired positions along the image acquisition path and an image processor constructs a 3-D volume of object data based on the 2-D fluoroscopic images. Patient information is displayed based upon the 3-D volume of patient information. A position tracking system is included to track the position of the receptor, patient and (if included) a surgical instrument. The position information is used to control the time at which exposures are obtained and (if included) to superimpose instrument graphical information on a display with patient information.
