PhotoSound Technologies, Inc. was founded in September 2015 in Houston, Texas USA to develop and commercialize new biomedical imaging technologies based on optics and photoacoustics. Photoacoustic tomography (PAT) is a biomedical imaging modality combining the molecular sensitivity of optical probes with the spatial resolution of ultrasound that is ideal for a multitude of applications that can be used for pre-clinical research. Using our skills to successfully translate the technology from its experimental form, we encompass the development of biomedical systems and associated software, including imaging instrumentation, complex electronic boards for data acquisition and control, transducers, sensors, and tunable lasers.
