— 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…

— Background
Image reconstruction for any modern imaging technique is an optimization problem. Most image reconstructions methods are iterative in nature and produce sequential intermediate images that are compared to the raw acquisition data and subsequently updated to maximize the likelihood that t…

— Technology Description
Researchers at Washington University in St. Louis have developed a device that automatically measures and displays body thickness to optimize X-ray image collection. This device will improve X-ray image quality and reduce the radiation exposure to patients.
The device es…
