Adaptive replanning using cone beam CT for deformation of original CT simulation

Journal of Medical Radiation Sciences, 2022
Background During a course of radiation therapy, anatomical changes such as a decrease in tumour size or weight loss can trigger the need for repeating a computed tomography (CT) simulation scan in order to generate a new treatment plan.

Scope of Nanotechnology in Radiation Treatment Planning

Procedia Materials Science, 2015
AbstractIn this paper an attempt has been made to study some of the elements of mathematical modeling in solid tumor growth. We present simple deterministic mathematical models used to describe tumor growth. Radiation therapy can be made very effective through the use of nanoscale particles such as gold nanoparticles, carbon nanotubes and magnetic ...
