Knee X-ray Image Analysis

[saja11]

I have to measure maximum anterior-posterior length of bones (condyles) in X-ray images of knee. I am using ImageJ (Fiji) software for that. However, one problem is that I have to incorporate the phantom of 30mm in the readings as well. How I can do scaling for that in ImageJ?

There is a calibrate function, but angles don't care about absolute linear measurements

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!
