The Kent Imaging device utilizes short wavelength near infrared light to determine tissue oxygen saturation. Short wavelength near infrared light penetrates a few mm into tissue making it ideal for microcirculation assessment. The strength of the Kent technology is that it provides a full field view of the injured or reconstructed tissue and is completely non-invasive. The images provided by our devices are readily interpreted and the information relates directly to the viability of tissue. Kent devices can be used for many application including wound care, reconstructive surgery and coronary artery bypass grafting (CABG).
