Radiotherapy performs an important function in the treatment of cancer, but resistance of tumor cells to radiation still remains a serious concern. More research on more effective radiosensitizers is urgently needed to overcome such resistance and thereby improve the treatment outcome. The goal of this study was to evaluate and compare the radiosensitizing efficacies of gold nanoparticles (AuNP...

Currently portal imaging devices are used to obtain information on patient localization during radiation therapy treatments. Such obtained information is two dimensional in nature, limited to the plane of the captured image. It has been proposed that megavoltage computed tomography images be reconstructed to overcome this limitation. This study explores the feasibility of reconstructing tomogra...

Dedicated rapid access palliative radiation therapy improves patients' access to care, allowing more timely treatment which would positively impact on quality of life. The TomoTherapy (Accuray, Sunnyvale, CA) system provides megavoltage (MV) fan-beam computed tomography (FBCT) as the image guidance technique, and a module called "statRT" that allows the use of these MV FBCT images for direct pl...

JULY/AUGUST 2010 ADVANCED OCULAR CARE 33 R adiation therapy has been evaluated extensively as a treatment for choroidal neovascularization (CNV) due to age-related macular degeneration (AMD) because of its antiangiogenic, antifibrotic, and anti-inflammatory properties.1-3 Historically, radiation for AMD has been delivered with two broad approaches: (1) radiotherapy with external beam (megavolta...
