QT Imaging is a medical technology innovator with a mission to directly improve and extend human life by reimagining the possibilities of imaging technology, and making its next-generation benefits accessible to all. With a first focus on improving breast imaging and breast health for women, we will extend our learning and technology for additional research, clinical and patient segments. Transmission Ultrasound is an emerging technology based on tomographic transmission ultrasound and capable of generating 3D speed-of-sound images. Our new non-invasive, radiation-free imaging tool may be used for diagnostic assessment of quantitative breast density (QBD), a volumetric breast density calculation that uses 3D transmission ultrasound, with results comparable to mammography with tomosynthesis. QT Imaging has received FDA 510(k) clearance to market its Transmission Ultrasound breast scanner. It is not intended as a replacement for screening mammography.
