Seno Medical Instruments, Inc. is a San Antonio, Texas-based medical imaging company committed to the development and commercialization of a new modality in cancer diagnosis: opto-acoustic imaging. Seno’s Imagio® breast imaging system fuses opto-acoustic technology with ultrasound (OA/US) to generate functional and anatomical images of the breast. The opto-acoustic images provide a unique blood map around suspicious breast masses while the ultrasound provides a traditional anatomic image. Through the appearance or absence of the two hallmark indicators of cancer – angiogenesis and deoxygenation – Seno believes that the Imagio® system will be a more effective tool to help radiologists confirm or rule out malignancy than current diagnostic imaging modalities – without exposing patients to potentially harmful ionizing radiation (x-rays) or contrast agents. The goal of opto-acoustic imaging is to allow more precise and earlier diagnosis of smaller tumors and the ability to differentiate benign from malignant growth without biopsy. Future applications will focus on other types of cancer and broader diagnostic and treatment applications.
