document: Mammogram synthesis using a 3D simulation . I. Breast tissue model and image acquisition simulation A method is proposed for generating synthetic mammograms based upon simulations of breast tissue and the mammographic imaging process . A computer breast model has been designed with a realistic distribution of large and medium scale tissue structures . Parameters controlling the size and placement of simulated structures -LRB- adipose compartments and ducts -RRB- provide a method for consistently modeling images of the same simulated breast with modified position or acquisition parameters . The mammographic imaging process is simulated using a compression model and a model of the X-ray image acquisition process . The compression model estimates breast deformation using tissue elasticity parameters found in the literature and clinical force values . The synthetic mammograms were generated by a mammogram acquisition model using a monoenergetic parallel beam approximation applied to the synthetically compressed breast phantom
