Title: SYSTEMS AND METHODS FOR PRODUCING REAL-TIME CALIBRATED STEREO LONG RADIOGRAPHIC VIEWS OF A PATIENT ON A SURGICAL TABLE
Abstract:
Tracked mobile x-ray imaging equipment is used to produce single or stereo long calibrated views of the anatomy of a patient on the operating table. The system estimates the position and orientation of the anatomical planes, virtually places measurement grids over these reference planes, and transforms any radiographic views taking by the x-ray imaging system onto these calibrated planes. The system may apply information about the depth of the anatomy to remove parallax artifacts. This system enables displaying and evaluation of the entire radiographic length of the anatomical planes using a mobile x-ray equipment. It also provides a platform for overlaying the real time x-ray images taken during operation with radiographic images of the patient or schematic of the surgical plan developed before the surgery for quick evaluation of a surgical plan.
