NON-INVASIVE BREAST CANCER DETECTION USING CO-REGISTERED MULTIMODAL PROBES: MICROWAVE NEARFIELD RADAR IMAGING (NRI), DIGITAL BREAST TOMOSYNTHESIS (DBT), ULTRASOUND IMAGING (US) AND THERMOACOUSTIC IMAGING (TA)

摘要

A cancer detection system may comprise at least two imaging systems, each of which implements a different imaging modality, and each of which provides sampled image data. The system may further include, for each imaging modality, a modeling unit to produce modeled image data based on a common set of biophysical parameters. The system may also include a joint non-linear inversion module to receive information from each modeling unit and reconstruct a set of joint biophysical properties. The system may include a scaling unit to revise the common set of biophysical parameters based on the set of joint biophysical properties. The system may include a comparator to compare the sampled image data from each of the imaging systems to the corresponding modeled image data to determine a difference between the sampled image data and the modeled image data, and to determine when the difference is less than a threshold difference.
