Panoramic cone beam computed tomography (CBCT) obtains full-scan CT images using only a half-scan rotation

Summary: Jenghwa Chang, Ph.D.

Technology Benefits: Accurate image reconstruction from half-scan data without sacrificing image volume or accuracy.Fewer scan angles decrease the potential for the gantry to collide with the rest table.Fewer scan angle results in reduced radiation exposure from the CBCT scanner.Can be deployed with existing conventional scanners.Patent information:Patent Pending (WO/2012/139031)

Technology Application: Deployment at a reconstruction algorithm for CBCT imaging in IGRT (image guided radiation therapy). Reconstruction of CBCT images in dentistry.Application to nuclear imaging (PET and SPECT).
