SENO Medical Instruments, Inc. was formed to commercialize a new modality in cancer screening and diagnosis: laser opto-acoustic imaging. Seno's patented technology integrates the use of lasers and acoustics to determine the presence of angiogenesis—the growth of blood vessels and higher blood volume that always surrounds a tumor. Unlike anatomical imaging techniques, such as mammography, laser opto-acoustic imaging can detect breast cancer, at its earliest clinically significant stage without patient discomfort or exposure to harmful x-ray.
