Software to Assess the Potential Accuracy of Radiation Planning Volumes in Head and Neck Cancer

Unmet NeedIn the United States, head and neck cancer represents 3% of all cancers, with approximately 66,000 individuals developing head and neck cancer annually (see uptodate.com). In the cases of localized head and neck cancer, radiation therapy provides improved outcome over surgery and is a preferred method of treatment. The success of radiation...

A GPU-accelerated Software Platform for Adaptive Radiation Therapy based on CT-CBCT (cone-beam CT) Registration with Iterative CBCT Intensity Correction, Automatic Segmentation, and Daily/Accumulated Dose Computation

Technology Overview A critical requirement of successful adaptive radiotherapy (ART) is the knowledge of anatomical changes as well as actual dose delivered to the patient during the course of treatment. While cone-beam CT (CBCT) is typically used to minimize the patient setup error and monitor daily anatomical changes, its poor image quality impedes...

A radiation treatment couch with integrated helical CT for on-line image guidance

Unmet NeedImage-guided radiation therapy (IGRT) denotes the use of imaging, usually CT scans and X rays, to precisely help target the cancer tissue with radiation therapy. This is specifically done through a flat-panel detector in cone beam computed tomography (CBCT) for IGRT. Flat panel CBCT imaging quality is degraded by several issues: 1) less than...

Method for Localizing Radiation Implants from Limited X-ray Data

C11152: Method for Localizing Radiation Implants from Limited X-ray DataValue Proposition: Johns Hopkins University inventors consider the 3-D implant localization as a seed-matching problem and a combinatorial optimization algorithm was formulated. It resolves the correspondence of identified seeds in every image even when a significant number of seeds...
