Dosimetric coverage of the prostate, normal tissue sparing, and acute toxicity with high-dose-rate brachytherapy for large prostate volumes.
PURPOSE To evaluate dosimetric coverage of the prostate, normal tissue sparing, and acute toxicity with HDR brachytherapy for large prostate volumes. MATERIALS AND METHODS One hundred and two prostate cancer patients with prostate volumes >50 mL (range: 5-29 mL) were treated with high-dose-rate (HDR) brachytherapy ± intensity modulated radiation therapy (IMRT) to 4,500 cGy in 25 daily fractio...
متن کاملA new tissue segmentation method to calculate 3D dose in small animal radiation therapy
BACKGROUND In pre-clinical animal experiments, radiation delivery is usually delivered with kV photon beams, in contrast to the MV beams used in clinical irradiation, because of the small size of the animals. At this medium energy range, however, the contribution of the photoelectric effect to absorbed dose is significant. Accurate dose calculation therefore requires a more detailed tissue defi...
متن کاملImpact of 4DPET/CT on normal tissue sparing for SBRT of central lung tumors
ESTRO 35 2016 _____________________________________________________________________________________________________ cm amplitude. A Fourier Transform (FT) was used to calculate the MTF of the images for the static and moving phantom. The MTF of five commonly used LOG filters were calculated. The response of the filters was compared with the MTF of the images to determine if the motion would aff...
متن کاملHow to Appropriately Calculate Effective Dose for CT Using Either Size-Specific Dose Estimates or Dose-Length Product.
OBJECTIVE The purpose of this study is to show how to calculate effective dose in CT using size-specific dose estimates and to correct the current method using dose-length product (DLP). MATERIALS AND METHODS Data were analyzed from 352 chest and 241 abdominopelvic CT images. Size-specific dose estimate was used as a surrogate for organ dose in the chest and abdominopelvic regions. Organ dose...
متن کاملExploiting Known Structures to Approximate Normal Cones
The normal cone to a constraint set plays a key role in optimization theory, algorithms, and applications. We consider the question of how to approximate the normal cone to a set under the assumption that the set is provided through an oracle function or collection of oracle functions, but contains some exploitable structure. We provide a new simplex gradient based approximation technique that ...
