Purpose: The purpose of this study is to develop the dedicated in‐house program for calculation of the monitor unit (MU) of proton therapy beam and to verify the feasibility of its clinical implementation in proton beam therapy with a combination ...
The energy spectra of high-energy electron beams used in radiotherapy are the most important data for evaluating absorbed doses and/or dose distributions in the body of a patient. However, it is impossible to measure the actual spectra of a high-e...
In external radiotherapy, the absorbed doses are measured using an ionization process in a gas-filled ionization chamber and estimated by the extended cavity theory. The calculation requires both the W-value of cavity gas and the restricted mass c...
