A table for the rapid determination of RET and TDF values.
A table has been devised to allow rapid determination of the RET and TDF values for five-day a week therapy schemes which might be included in realistic treatment planning. 2. The table allows easy comparison of the RET and TDF values for different fractionation schemes or, conversely, the devising of equivalent fractionations for similar RET and TDF values. 3. Utilizing the decay tables of Orton and Ellis, it is possible to utilize the table for determining rapidly the total TDF for interrupted or split course treatment regimens. 4. In those departments which treat four days, rather than five days, per week, a table devised on the four-day treatment schedule could easily be devised.
