— 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…

— 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…

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…
