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. Total dose given — the sum of all the doses received. It is equal to the number of fractions multiplied by the dose in one fraction in Grays — Gy. The biologically effective dose BED formula, created in , is an efficient way of defining treatment expectations. It helps clinicians make decisions regarding further treatment and its quantitative assessment. The BED equation is based on the linear dependence of cells' survival , used in radiobiology. BED is mostly used to compare different types of treatment and report research results. You may also add different BED results to receive the final dose of the treatment.

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.

Here are a few tips on how to best utilize these tools. However, 3 Gy and 10 Gy are often used for late and early tissues for general clinical purposes, respectively. These examples apply for all ClearCheck versions 2. To begin, we need to have the correct course and plan opened and the desired constraint template. It can also combine the doses from courses of treatment that do not have a similar fractionation scheme. One example would be to evaluate the cumulative Spinal cord max dose from a previous treatment plan treated with cGy x 30 to the current SBRT treatment plan treated as cGy x 5. Many retreatment limits on the cord, brainstem, bowel, etc. The standard approach uses the entire plan sum DVH based on the re-binning of dose voxels in each plan with appropriate fraction numbers applied.

Dose converters: There are, actually, two dose converters, one is used when you know new dose per fraction and would like to calculate equivalent number of fractions, and the other is used when you know new number of fractions and need to calculate new dose. Next Review: July 6, Biologically equivalent doses are calculated in 2-Gy equivalents using the EQD 2 equation. Quickly calculate radiation dose in equivalent 2 Gy fractions and biological equivalent dose BED. Total Dose: - Gy. The fast proliferation in early responding tissue causes a majority of cells to spend time in the most radioresistant S phase. Languages English.
