Eqd2 calculator

If you would like to skip the eqd2 calculator, links to dose converters are at the bottom of this page. Isoeffective dose is described by the following equation:.

The BED calculator is a simple way to assess the biological effect of radiotherapy treatment. You can find both the biologically effective dose and the equivalent total dose in 2-Gy fraction EQD2. In the article below we will explain BED calculation formula, the BED dose usage , and the theoretical basis of our radiotherapy dose calculator. Longer than a few minutes — a slowly delivered fraction is a way to lessen the side effects of the treatment. Dose given per fraction — dose received during single irradiation in Grays — Gy.

Title updated to include EQD2. Updated 'Biological equivalent' to 'Biologically effective' to reflect calculator formula. Added references for calculation formulas. Furthermore, changes in circumstances after the time of publication of the Information may impact on the accuracy of the information. The biologically effective dose and equivalent dose in 2Gy calculators are based on the Linear Quadratic Model. As with any model there are limitations including the lack of a time factor and its applicability for low doses per fraction 1. The doses are calculated as a guideline to allow conversion and comparability of different fractionation schemes. Clinical decisions based on this are the responsibility of the radiation oncologist.

Quickly calculate radiation dose in equivalent 2 Gy fractions and biological equivalent dose BED. This app includes a selectable list of alpha beta values of normal tissues and tumors. This app features a dose conversion mode in order to calculate a custom dose per fraction. This app has been updated by Apple to display the Apple Watch app icon. Support for iPhone X. The developer, Jon Giambattista , has not provided details about its privacy practices and handling of data to Apple.

Biologically equivalent doses are calculated in 2-Gy equivalents using the EQD 2 equation. To embed this calculator, please copy this code and insert it into your desired page:. Then you can click on the Print button to open a PDF in a separate window with the inputs and results. You can further save the PDF or print it. The concept of biologically effective dose is useful for quantifying treatment expectations, with the caveat that careful interpretation of modelling results is required before clinical decisions are made. Correct use of BED calculations often involves the collaboration with other patient parameters.
