— Quality assurance is critical in the setup and operation of linear accelerators (LINACs) and requires significant time and expense
Before they can be put into use, new LINAC radiotherapy machines and their integrated treatment planning systems (TPSs) must go through a labor-intensive acceptance and…
— 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…
— Technology Description
Researchers in Patricia Weisensee’s lab at Washington University have developed a compact liquid metal heat switch with a passive mechanism to control the thermal management system of spacecraft. Unlike other switch mechanisms, the liquid metal version produces high co…
— 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…
