ABSTRACT:
A method of imaging a patient's uncompressed region of interest using X-ray cone beam computed tomography or cone beam digital tomography comprises the step of introducing an effective amount of a contrast agent to the uncompressed region of interest. A system for imaging a patient's uncompressed region of interest using cone beam computed tomography (CBCT) or cone beam digital tomography (CBDT) comprises an X-ray source transmitting an X-ray to the uncompressed region of interest, an image acquisition system acquiring a plurality of two-dimensional projection images data for a CBCT or CBDT data set with at least one of the projection images acquired in 35 milliseconds or less, and a processor generating a three-dimensional computed tomography image data set resolving voxels with dimensions of 0.4 mm or less in at least two orthogonal directions.
