where can i get a clear understanding of this topic. seen khan, IAEA . please suggest .mainly confusion is that for photons in compton range the absorbed dose depends on electrons/gm which is less for bone than soft tissue thus less dose in bone than soft tissue. but beyond bone in the soft tissue the concept of shielding effect of bone as bone has higher electron density than soft tissue. i am confused for compton range when are we looking at electron density(linear attentuation ) and when at electrons pper gram (mass attentuation). absorbed dose depends on photon fluence and mass energy abs coeffient.

Given the beam angle and the scan info, let the (i,j)-th entry of the matrix D, i.e. D_{i,j}, denote the dose deposited to voxel i by unit intensity of beamlet j of the beam. How is D calcuated?
