Optimization and Comparison of Different Digital Mammographic Tomosynthesis Reconstruction Methods
Abstract
Digital breast tomosynthesis is a three dimensional imaging technique with limited angle series of projection images that allows the reconstruction of an arbitrary set of planes in the breast. Compared with standard mammography techniques, this method improves conspicuity of structures by removing the visual clutter associated with overlying anatomy. The objective of this project is to optimized and compare different tomosynthesis methods and choose the optimal one for breast imaging. Optimization of acquisition parameters will provide better reconstruction images of the breast, and related deblurring methods can remove out of plane blurred structures. We investigated several 3D tomosynthesis reconstruction algorithms and studied the effect of acquisition parameters for different reconstruction algorithms, according to physical measurements of impulse response analysis, modulation transfer function (MTF) and noise power spectrum.
