QT IMAGING HOLDINGS, INC.

QT Imaging Holdings, Inc. is a medical device company engaged in the research, development, and commercialization of innovative body imaging systems using low energy sound. The company was founded in 2012 as QT Ultrasound LLC, which focused on the research, development, and commercialization of these systems. On December 31, 2020, QT Ultrasound LLC converted to QT Imaging, Inc. and revoked its limited liability company election status. On March 4, 2024, QT Imaging, Inc. became a wholly owned subsidiary of GigCapital5, Inc., which was subsequently renamed QT Imaging Holdings, Inc. The company is headquartered in Novato, California. QT Imaging has developed a novel, comprehensive body imaging technology designed to produce high-resolution volumetric images of breast tissue using low-energy transmitted sound. This technology is based on ultra-low frequency transmitted and reflected sound waves. It utilizes a proprietary sound back-scatter design along with inverse-scattering reconstruction algorithms to generate quantitative three-dimensional images of tissue properties. The company has received nearly $18 million in financial support from the U.S. National Institutes of Health for the development of this technology.
