Abstract

This Research has been conducted for the absorbed dose calculation in rotational treatment with Tissue Phantom Ratio (TPR) method. The purpose of this study to determine the absorbed dose comparisons on rotational therapy based on calculations and measurements. The study was conducted in a solid water phantom with 100 cm SAD. The study was conducted on a square field area of 5 cm x 5 cm, 7 cm x 7 cm and 10 cm x 10 cm as well as on equivalent field area of 10 cm x 10 cm, consist of 8 cm x 13,3 cm and 9 cm x 11,5 cm area. The result is percentage of difference between the value of measurements and calculations dose on each field area. The field area which have percentage below the tolerance value is a 7 cm x 7 cm with the percentage of difference of 0.46%. For the field area of 5 cm x 5 cm has a percentage of difference of 2.65%, while the area of 10 cm x 10 cm and equivalent field area the percentage of difference were high at more than 3%.
