Digital mammography image simulation using Monte Carlo.

چکیده
Monte Carlo simulations of digital images of the contrast detail phantom and the ACR phantom are presented for two different x-ray digital mammography modalities: a synchrotron mammography system and a next-generation scanning slot clinical system. A combination of variance reduction methods made it possible to simulate accurate images using real pixel dimensions within reasonable computation times. The complete method of image simulation, including a simple detector response model, a simple noise model, and the incorporation of system effects (MTF), is presented. The simulated images of the phantoms show good agreement with images measured on the two systems.

متن کاملEstimation of scattered radiation in digital breast
13 Digital breast tomosynthesis (DBT) is a promising technique to overcome the tissue 14 superposition limitations found in planar 2D X-ray mammography. However, as most 15 DBT systems do not employ an anti-scatter grid, the levels of scattered radiation 16 recorded within the image receptor are significantly higher than that observed in planar 17 2D X-ray mammography. Knowledge of this field i...
