Paper Abstract

The application of numerical multiparameter optimization techniques tolthe design of improvqd mammographic imaging systems has been discussed by Jafroudi et al., and by Muntz et al.. The approach taken requires the specification of a reference system for dios/p and imaging performance comparisons. The optimized designs that have been reported are based on a reference system without a grid. Since those designs were developed, it has become common practice to use grids in mammography. Accordingly, the optimization has been repeated with a current state-of-the-art system, including a grid, as the reference. An approximation to the revised optimized design has been assembled and compared to a Thomson-CGR Senographe 500T mammography unit equipped with a grid. When the optimized system is operated under conditions that produce imaging performance comparable to that of the Senographe, the average glandular dose delivered by the optimized system is about 1/3 the dose delivered by the Senographe.
