National Cancer Institute
QT Ultrasound has received $16 million in funding from NIH-National Cancer Institute. This is focused on the development of a new ultrasound tomography system for breast cancer detection. The goal of this ‘translational’ funding is to translate the pre-clinical prototype into a clinically useful, patient-friendly device, by optimizing image quality and speed of reconstruction.
