The processing algorithm, although developed initially for thermograms, is equally valid for other diagnostic imaging techniques and could be of use where it is required to isolate vascularity or other fine detail from larger body structures.
Optimum X-ray spectra for mammography
- S A Beaman, S C Lillicrap
- Physics
- 1982
A number of authors have calculated optimum X-ray energies for mammography using, as a criterion, the maximum signal-to-noise ratio (SNR) obtainable per unit dose to the breast or conversely the…
Optimum x-ray spectra for mammography: choice of K-edge filters for tungsten anode tubes
- C P McDonagh, J L Leake, S A Beaman
- Physics
- 1984
The experiments reported show that if the optimum energies calculated by D. Dance and G. Day (see Proc. Seminar Patient Exposure Med. x-ray Diag., Munich, Germany, p.227-44, 1981), based on maximum…
