TDFCalc is an application which implements the linear-quadratic (LQ) method for comparing the biologically effective dose (BED) of external beam radiation therapy (EBRT) fractionation regimens as well as low dose rate (LDR) and permanent implant brachytherapy treatments. It calculates BED for a given alpha/beta ratio as a function of the dose per fraction and number of fractions for EBRT, and initial dose rate for brachytherapy. For a predetermined BED, the app solves the quadratic equation to calculate dose per fraction as a function of the number of fractions desired. This enables quick comparison of modified fractionation regimens (e.g. hypofractionation or compensating for missing treatment fractions) vs a conventional and/or originally intended regimen.

Reviews of TDF Calc

Very nice very simple application for getting BED calculations.

This app can be thought of as a light version of the "TDF Plan" software available for desktops. This is a good first version application, but it may be priced too highly at 9.99 without adding additional features.

Despite inheriting the TDFCalc name the application only calculates BED's. BED is the new standard, however it is often useful to compare BED results with TDF results when discussing the matter with a college. I would also love it if this application could email a simple report of the calculation.

It would be nice to add support for additional features such as:
1. In ESC calculator: ability to specify dose for new regimen and see closest #fractions needed
2. Button to turn on TDF comparison (ex. BED ESC 17fx at 250cGy, TDF = X fx at 250cGy).
3. Support for multiple courses of treatment (i.e. save regimen as course).
4. HDR, CyberKnife settings
5. Landscape view for viewing multiple courses and results of ESC calculator all on one screen.
