Image restoration (Denoising)

This project aims at improving image quality of x-ray images by developing appropriate image restoration techniques. The methods have been validated on Digital Mammography, Digital Breast Tomosynthesis and Molecular Breast images. A pre-clinical trial was conducted using clinical DBT patient data and human observers. A clinical trial is currently being conducted using MBI images and radiologist at a major clinical center in the USA.

Software

MC Insertion Package - Includes function, example code, and 11 segmented clusters of microcalcifications acquired using a Hologic system. Implemented using MATLAB R2016a. (v 1.0, 02/05/2019)
