Abstract

C-arm enables a great variety of movements, and its characteristic structure makes it possible its use in intraoperative cases, as the arc can be located around a patient lying in the bed. Such a device is conventionally intended to obtain planar images with no depth information. Our group is evaluating the use of the C-arm to provide 3D imaging guide to Intraoperative Radiation Therapy procedures. For the use of the C-arm in computerized tomography, mechanical calibration becomes an important issue, as many parameters influence the quality of the reconstruction: center of rotation, detector position, distance between detector and source, etc. In this work, we present preliminary results of the implementation of a calibration method needed to generate tomographic images with a C-arm system.
