Breast Microcalcification Detection Using Super-Resolution Ultrasound Image Reconstruction
Abstract
We explore the use of the super-resolution ultrasound imaging method for detecting breast microcalcifications. We validate and test its imaging capability using numerical breast phantom data. We also study breast microcalcification detection using wave-equation reflection/migration imaging. Wave-equation reflection/migration imaging can effectively reduce image speckles by properly handling ultrasound scattering/diffraction from breast heterogeneities during image reconstruction. We construct numerical breast phantoms using in vivo breast images, and use a time-domain finite-difference wave-equation scheme to generate ultrasound data scattered from inclusions that mimic microcalcifications. Our numerical phantom studies show that microcalcifications can be detected at full spatial resolution using both the super-resolution ultrasound imaging and wave-equation migration/reflection imaging methods.
