Meet the doctors, scientists, and engineers behind the QTscan

Company Overview

QT Ultrasound is a privately held technology company engaged in the research, development and commercialization of an innovative automated breast imaging system producing high-resolution transmission ultrasound images.

Approximately 39 million women, in the United States, get mammograms every year (source: CDC). For every 1 woman with cancer, 19 more will be told they might have cancer when they don’t. The cost, time, and psychological distress takes an enormous toll. We exist to change the paradigm of breast imaging and to keep women from going through the trauma of this journey. It’s why the FDA granted clearance for the QTscan as an adjunct to mammography, and the National Institutes of Health (NIH) awarded $16 million in funding to continue QT Ultrasound research.
