TDF (Time-dose factor) in the treatment of carcinoma of the uterine Cervix using high and low-dose rate

Abstract

This paper shows the calculation of the TDF of low and high dose rate intracavitary radiotherapy.  TDF from different techniques are also shown.  TDF for optimum therapy and a quick reference for high dose rate TDF are suggested.  For high dose rate the TDF at point B is 16.7% of point A and it is 20.8% in low dose rate.
