Paper Abstract

(General Comment) You have stated that the performance specifications of modern densitometers exceed the needs of radiology for routine densitometric checks. If the acceptable range of density variation in the finished radiograph is of the order of 0.2 as has been stated by some speakers, and if you accept the usual rule that the precision of a measuring instrument should be ten times as good as that of the process being measured, then the instrument should have a precision of 0.02, which is axactly what is specified by densitometer manufacturers.
