NIH Awards QT Ultrasound over $15M in Research Grants

National Cancer Institute

QT Ultrasound has received over $15 million in grants 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.
