Background:
Tomosynthesis is a new technology of digital mammography that enables the acquisition of a three - dimensional image and allows visualization of cancers not apparent by conventional mammography. Ultrasound (US) is also used for tumor monitoring, which is highly operator dependent and has some problems with reproducibility. US is also an easily available and noninvasive modality. Our goal is to have a comparison between breast ultrasound and tomosynthesis to determine which modality is better.
