Radiation Oncology

Radiation oncology is a medical specialty that uses radiation therapy to treat cancer. The radiation therapy channel covers all aspects of radiation oncology technology. Radiation therapy includes linear accelerators (LINAC), proton therapy, brachytherapy, image guided radiation therapy (IGRT), focused ultrasound, stereotactic body radiation therapy (SBRT), intensity modulated radiation therapy (IMRT), treatment planning systems and tomotherapy.

(a) A schematic of cycloidal computed tomography (not to scale, seen from top); by adding an array of beam stops in front of the detector, the setup is transformed into an edge-illumination x-ray phase-contrast imaging device. (b) A sinogram sampling grid for a rotation-only scheme. (c) A sinogram sampling grid for a cycloidal scheme. The grids are shown for one mask period and a subset of rotation angles; the combination of empty and filled circles shows the grids that would be achieved through fine latera

In I-131 cancer therapy, decay events damage sensitive DNA within a tumor cell nucleus, causing catastrophic single and double strand breaks. Clinical use of antibody-delivered Auger emitters could open a window for the targeted destruction of extracellular COVID-19 virions, decreasing the viral load during active infection and potentially easing the disease burden for a patient.

Total-body dynamic 18F-FDG PET imaging with the uEXPLORER scanner allows us to monitor the spatiotemporal distribution of glucose concentration in metastatic tumors in the entire body (a). As compared to a typical clinical standardized uptake value image (b), the parametric image of FDG influx rate (Ki) can achieve higher lesion-to-background (e.g., the liver) contrast. In addition to glucose metabolism imaging by Ki, total-body dynamic PET also enables multiparametric characterization of tumors and organs
