Adding 166Ho data to VARSKIN2 code and dose calculation to human skin

Background: Skin cancer can be treated by various methods. Electron radiotherapy has been a useful therapeutic modality in the treatment of skin cancers in areas which are difficult to cure by other methods. Depth dose distribution of 166Ho using VARSKIN2 code is presented in this work. Material and Methods: Depth dose distribution of 166Ho was calculated, using VARSKIN2 code by adding...

VISRAD Benchmark Calculation: OMEGA Capsule Radiation Symmetry

In these indirect-drive experiments, up to 40 of the 60 OMEGA laser beams enter the hohlraum laser entrance holes (LEHs). The beams are arranged in 3 cones, with entrance angles (i.e., half-cone angles) of 21.42°, 42.02°, and 58.85° for Cones 1, 2, and 3, respectively. The pointing of the cones was adjusted in a series of 3 experimental scans to assess the effects of the beam pointing on the ca...

Benchmark Dose Estimation Using SAS®

Toxicologically-based quantitative risk assessment is concerned with estimating human risks based upon experimental data linking an environmental agent to a known outcome (tumor incidence, acute toxicity, etc.). For dichotomous outcomes dose-response curves are modeled as complex functions of dose which often require specialized software to estimate. The SAS procedure NLMIXED readily allows for...

Simulation of beam record data for 4D dose calculation

Treatment of moving targets can result in local over and under dosage due to interference effects of the beam application and the motion of the target. First experimental studies [1] as well as theoretical works [2, 3] showed that multiple irradiations with an accordingly reduced dose per irradiation reduce these inhomogeneities due to averaging effects. If the multiple irradiations are perform...
