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...

BACKGROUND 90Y PET/CT post-radioembolization imaging has demonstrated that the distribution of 90Y in a tumor can be non-uniform. Using computational modeling, we predicted the dosimetric impact of post-treatment 90Y PET/CT-guided percutaneous ablation of the portions of a tumor receiving the lowest absorbed dose. A cohort of fourteen patients with non-resectable liver cancer previously treated...

a lithium borate thermoluminescence dosimeter with 0.3 wt% of manganese impurityconcentration was prepared for high dose levels in the range of 1-30 kgy for gamma irradiation applications.the tld reader was used for read out purposes from ambient temperature to about 400°c with a heating rate of 6°c/sec. the pre- and post- irradiation anneal temperature was 300°c for 1.5 and 1 hours respectivel...

Background: A new treatment approach for most patients who have undergone early stage non-small-cell lung carcinoma (NSCLC), is wedge resection plus permanent implant brachytherapy. However, the specification of dose to medium at low energies especially in heterogeneous lung is unclear yet.Objective: The present study aims to modify source strength for different configurations of 125I and 103...

voriconazole is an antifungal triazole, approved for management of invasive fungal diseases in patients. it is absorbed during two hours and its serum levels will be above 90%, based on the underlying factors, when the drug is administered orally. voriconazole shows a propotional increase in an area under the plasma concentration-time curve (auc), with increasing dose. plasma protein binding of...

A study was made on the loss of the reproductive capacity of HeLa S3 cells irradiated in vitro under both oxygenated and anoxic conditions with D-T neutrons (14 Mev) at 1, 20, 30, 150 and 400 rads/minute at 25•Ž and 37•Ž and with 180 kvp X-rays at 100 rads/minute at 37•Ž. 1) RBE of neutrons measured at a range of 2 to 10% survival was 2.67-2.62 under oxygenated conditions and 3.83.4.61 under an...
