Tetrahedron Beam Computed Tomography with Multi-pixel X-ray Source
Zhang, Tiezhi
T-015342

— About 70 million computed tomography (CT) scans are performed in the United State alone each year. Traditional helical scanners use a single point x-ray source that rotates around the patient, acquiring images in sequential slices, which results in high quality images. But these helical scanners a…

Super-Resolution Dental Tetrahedron Beam Computed Tomography (TBCT) System Improves Image Quality Without Sacrificing Speed for Expanded Clinical Applications

T-019620

— Current cone beam computed tomography (CBCT) systems lack concurrent high-resolution imaging and speed With current digital CBCT imaging technology, x-ray tube power limitations mean high-resolution images can only be achieved by reducing imaging speeds. In dental applications, CBCT suffers from im…

Optimized Non-Coplanar Radiation Delivery for Simpler, Faster, and Safer Treatments
Mutic, Sasa ; Zhang, Tiezhi
T-016307

— Existing LINACs inefficiently deliver non-coplanar beams The goal of radiation treatment is to precisely deliver a prescribed radiation dose to the targeted tissue, while avoiding dosing the surrounding normal tissues and organs. These treatments require radiation beams to be delivered from multipl…
