چکیده
The brain is an organ that jealously guards its mysteries. Not only is it a complex structure, its function is also incompletely understood. For example, while researchers know that the nerve cells in the hippocampus region are critical to learning and memory, little is understood about how these critical functions that define humanity actually take place. Further, when something goes awry – like Alzheimer's or Parkinson's disease – it is a challenge to understand exactly how the brain has been affected.

Comparison of daily versus nondaily image-guided radiotherapy protocols for patients treated with intensity-modulated radiotherapy for head and neck cancer.
BACKGROUND The purpose of this study was to determine the feasibility of nondaily image-guided radiotherapy (RT) strategies with intensity-modulated radiotherapy (IMRT) for head and neck cancer. METHODS Alignment data was analyzed from 103 consecutive patients treated by IMRT for head and neck cancer who had undergone daily imaging with onboard mega-voltage CT (MVCT), resulting in 3275 images...
متن کاملComparison of state-of-the-art atlas-based bone segmentation approaches from brain MR images for MR-only radiation planning and PET/MR attenuation correction
Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...

متن کاملDefinitive Radiotherapy for Squamous Cell Carcinoma of the Glottic Larynx.
BACKGROUND Depending on the extent of disease, squamous cell carcinoma (SCC) of the glottis is managed with surgery, radiotherapy (RT), or a combination of these modalities. Patients with advanced disease may receive concomitant chemotherapy in conjunction with definitive or postoperative RT. METHODS The treatment policies of the University of Florida and patient outcomes are reviewed. RESU...
متن کاملPerforming radiation therapy research using the open-source SlicerRT toolkit
Radiation therapy (RT) is a common treatment option for a wide variety of cancer types. Despite significant improvements in this technique over the past years, software tools for research in RT are limited to either expensive, closed, proprietary applications or heterogeneous sets of open-source software packages with limited scope, reliability, and user support. Our SlicerRT toolkit aspires to...
