Breast Cancer Clinical Trial
Case Collection Study to Determine the Accuracy, Call Back and Cancer Detection Rates of QT Ultrasound in Breast Imaging
Summary
Brief Summary: The QT Ultrasound system is an automated scanner which transmits pulsed ultrasound plane waves through the breast, as well as collects reflected ultrasound output. As the patient lays prone on a table, the breast is submerged in a warm water bath. The transmitter and receiver assembly moves around the suspended breast to record data for successive sub-volumes of targeted tissue. More than 2000 elements in the curvilinear transducer's array encircle the breast to gather data from the tissue structures of the breast, from nipple to chest wall. Information gathered from this automated QT scan encompasses the entire breast which is currently not commercially available using any other ultrasound technology.
Full Description
This is a prospective, multicenter, multi-arm case collection study, with IRB approval. The study will follow an adaptive design with an initially planned total enrollment of approximately 600 cases to include both benign and malignant cases, representative of all tissue densities.
The images and clinical data accrued in this prospective case collection will be used for creation of a database to facilitate future reader's studies, publications, building teaching files, and future marketing for QT Ultrasound.
