Estimation of tumor dose in conformation radiotherapy.

Dosage estimation for conformation radiotherapy applied to cervical cancer was discussed. Field size and shape in conformation therapy was freely change able according to the shape and size of tumor. When the same size and shape of the field for therapy by Co 60 gamma ray was applied to each case, tissue-air ratio TAR was given by an equation, T=-0.00326d+1.035, where T is TAR and d an average ...

Improvement of dose delivery with loading of tumor with gold nanoparticles in orthovoltage radiotherapy

Introduction: To enhance the dose to tumor, the use of high atomic number elements has been proposed. Objective: The aim of this study is to investigate the effect of gold nanoparticle distribution on dose enhancement in tumor when the tumor is irradiated by typical monoenergetic X-ray beams by considering homogeneous and inhomogeneous distributions of gold nanoparticles (GNPs)...

Skin dose during radiotherapy: a summary and general estimation technique

The skin dose associated with radiotherapy may be of interest for clinical evaluation or investigating the risk of late effects. However, skin dose is not intuitive and is difficult to measure. Our objectives were to develop and evaluate a general estimation technique for skin dose based on treatment parameters. The literature on skin dose was supplemented with measurements and Monte Carlo simu...
