Implication

Dosimetric modeling study demonstrates a transformed volume-dose histogram for interstitial brachytherapy, enabling clear quantitative assessment of dose rate uniformity.

Key Points

To formulate a volume-dose histogram for brachytherapy that suppresses inverse square law effects while maintaining volume proportionality to the area under the curve.
Formulated a mathematical transformation plotting volume per unit -3/2 power of dose rate against the -3/2 power of dose rate.
Modeled and evaluated the resulting graphical distributions for single point sources and multi-source interstitial implant configurations.
The transformed distribution yields a constant horizontal baseline for a single point source, neutralizing inverse square law distortions.
Combining multiple radioactive sources generates a distinct peak whose width, position, and contained volume directly quantify dose rate uniformity in interstitial implants.
