QT IMAGING HOLDINGS, INC.

QT Imaging Holdings, Inc. is a medical device company founded in 2012, engaged in the research, development, and commercialization of innovative body imaging systems using low energy sound. 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 and utilizes a proprietary sound back-scatter design together with inverse-scattering reconstruction algorithms to generate quantitative three-dimensional images of tissue properties. The company received nearly $18 million in financial support from the U.S. National Institutes of Health for its technology development. On December 8, 2022, GigCapital5, Inc., a special purpose acquisition company incorporated in Delaware in 2021, entered into a Business Combination Agreement with QT Imaging, Inc. The Business Combination closed on March 4, 2024, resulting in QT Imaging, Inc. becoming a wholly owned subsidiary of GigCapital5, which was subsequently renamed QT Imaging Holdings, Inc. QT Imaging, Inc. was incorporated in Delaware on December 31, 2020, converting from its predecessor, QT Ultrasound LLC, which was formed in 2012.
