The high density and atomic number of hip prostheses for patients undergoing pelvic radiotherapy challenge our ability to accurately calculate dose. A new clinical dose calculation algorithm, Monte Carlo, will allow accurate calculation of the radiation transport both within and beyond hip prostheses. The aim of this research was to investigate, for both phantom and patient geometries, the capa...

abstractbackground: polymer gels are an emerging new class of dosimeters which are being applied to the challenges of modern radiotherapy modalities. research on gel dosimetry involves several scientific domains, one of which is the imaging techniques with which dose data is extracted from the dosimeters. in the current work, we present our preliminary results of investigating capability of x-r...

background: the dosimetric parameters required in lung cancer radiation therapy are taken from a homogeneous water phantom; however, during treatment, the expected results are being affected because of its inhomogeneity. therefore, it becomes necessary to quantify these deviations. objective: the present study has been undertaken to find out inter- and intra- lung density variations and its dos...

A Monte Carlo method for modeling the light transport phenomena in organic polymer light-emitting devices (PLEDs) has been reported by our group. [1] The unique advantage of this method is its ability to model bulk absorption events, thin film coatings, and rough surfaces while keeping track of the photon polarization state in a realistic geometry of the devices. We have applied this method to ...

Electron beam radiation therapy is used extensively for treating head and neck cancers to avoid the irradiation of the spinal cord. It is also used for treating chest wall malignancies to limit the irradiated volume of lungs. Calculating the dose distribution from an electron field is quite complicated because of the multiple scattering, especially in the presence of internal heterogeneities [1...
