Abstract

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.

Description

Background of the invention

[0001] Preferred embodiments of the present invention generally relate to x-ray systems based on a mobile C-arm for constructing three-dimensional (3-D) volumetric data sets and using the data in diagnostic and interventional medical procedures set. More specifically, at least one preferred embodiment of the present invention relates to an x-ray medical imaging system based on a mobile C-arm that processes a three-dimensional volumetric data set of digital x-ray images based in part on patient and x-ray receiver coordinate information. Construct and use this data set for the diagnostic and interventional procedures to be performed.

[0002] Conventional medical imaging equipment, such as computed tomography (CT) and magnetic resonance imaging (MRI), use complex mechanical gantry structures to support the patient and the devices used to construct patient imaging datasets. CT and MRI data sets are formed from multiple scans in which the exact positi...
