Dose-to-tissue is the quantity ‘

inherently

’ computed by MCTP. This may be

of more clinical relevance than the doses on which historical clinical

experience is based, which are approximate estimates of the true dose in the

The difference between

and

for tissue-equivalent materials is

rather small

and ‘

is likely

’ to have

minimal impact in clinical

practice

❑

Converting

back to

involves ‘

additional complexity

’ and

introduces

additional uncertainty.
