QT Imaging is a medical technology company focused on improving breast imaging and breast health for women. They have developed a non-invasive, radiation-free imaging tool called Transmission Ultrasound, which generates 3D speed-of-sound images for diagnostic assessment of quantitative breast density. The technology has received FDA 510(k) clearance for marketing, but is not intended as a replacement for screening mammography. QT Imaging aims to extend their technology to additional research, clinical, and patient segments.
