Computer assisted analysis of tomographic mammography data
First Claim
1. A method for analyzing mammography data acquired by a tomographic system, comprising:
- acquiring a tomographic data set from a tomographic mammography system;
segmenting the tomographic data set into one or more segmented data sets;
processing one or more features of the one or more segmented data sets to produce one or more feature-processed data sets; and
providing the one or more feature-processed data sets to a reviewer.

Abstract
The present technique provides a method and system for generating tomographic mammography data and processing the data using a computer aided detection and diagnosis (CAD) algorithm. The CAD algorithm may perform various types of analysis, including segmentation, feature extraction, and feature classification. The acquired data may be processed in parallel by the CAD algorithm such that information derived from one processing path may be used to enhance or alter the processing of data in a parallel processing path. The processed data may be used to provide an enhanced mammographic image with features of interest marked for inspection by a radiologist. The features of interest may also be classified to aid the inspection by the radiologist.
