Hi All,
I recently submitted a Dose Mapping study to an Auditor and have a query back from them:
"The calculation on page 8 of the Dose Mapping Study used addition and subtraction to calculate the maximum and minimum doses. This is a proportional calculation and should be presented as such.
> Please recalculate the routine dose based on proportional calculation."
The way we had calculated it was like this:
Difference between routine position (D1) and minimum dose (A3) = 31.9 kGy ? 30.7 kGy = 1.2 kGy
Therefore minimum dose accepted at routine position (D1) = 25 kGy + 1.2 kGy = 26.2 kGy
Difference between maximum recorded dose (C5) and routine position (D1) = 39.3 kGy ? 31.9 kGy
= 7.4 kGy
Therefore maximum dose accepted at routine position (D1) = 50 kGy (max allowed dose) ? 7.4
kGy = 42.6 kGy
Can anyone please comment on how we should be presenting this information?
thanks in advance, we are a bit stumped!
