PURPOSE To assess individual variation in heart volume and location in order to develop a prediction model of the heart. This heart prediction model will be used to calculate individualized heart doses for radiotherapy patients in epidemiological studies. METHODS Chest CT images for 30 adult male and 30 adult female patients were obtained from NIH(More)
PURPOSE Irradiation of the lens during a neck CT may increase a patient's risk of developing cataracts later in life. Radiologists and technologists at the National Institutes of Health Clinical Center (NIHCC) have developed new CT imaging protocols that include a reduction in scan range and modifying neck positioning using a head tilt. This study will(More)
Abstrakt Nejčastějšı́m způsobem komunikace při e-výuce a aktivitách typu blended learning zůstává stále dokument či e-dokument, at’ již to je skriptum, prezentace, webová stránka nebo e-mail. Přesto kvalita dnešnı́ho elektronického publikovánı́ zaostává za kvalitou, kterou u klasických publikacı́ dosahovali mistři černého řemesla před sto lety. V článku(More)
PURPOSE This study aims to develop a tool to rapidly delineate cardiac substructures for use in dosimetry for large-scale clinical trial or epidemiological investigations. The goal is to produce a system that can semi-automatically delineate nine cardiac structures to a reasonable accuracy within a couple of minutes. METHODS The cardiac contouring tool(More)
PURPOSE Epidemiological studies of second cancer risks in breast cancer radiotherapy patients often use generic patient anatomy to reconstruct normal tissue doses when CT images of patients are not available. To evaluate the uncertainty involved in the dosimetry approach, we evaluated the esophagus dose in five sample patients by simulating breast cancer(More)
