background: the purpose of this study was to evaluate nodal irradiation with conventional three-field's technique. materials and methods: fifty patients with breast cancer were enrolled in this study. computed tomography scans in the supine treatment position were imported into a treatment planning system. levels i-iii axillary and supraclavicular nodes were identified and their depths to ...

background: advances in radiation dosimetry concepts and the development of primary measurement standards based on absorbed dose to water over the last decades offer the possibility to calibrate ionisation chambers directly in terms of absorbed dose to water. the aim of this study is the investigation on utility of artificial body fluid (abf) instead of water by comparing dosimetric measurement...

The purpose of this study was to validate the dosimetric performance of Varian surface applicators with the source vertically positioned and develop procedures for clinical implementation. The Varian surface applicators with the source vertically positioned provide a wide range of apertures making them clinically advantageous, though the steep dose gradient in the region of 3-4 mm prescription ...

Sometimes I feel like JFK, roaming a city of free (scientific) thinking surrounded by a wall of lack of recognition at best, of hostility at worst. The advance of knowledge relies not only on what we produce as scientists, but also on the evaluation of our work by our peers. The review process plays an essential role in making the science that we publish stronger. We are acknowledged for the wo...
