Seno’s technology produces high-resolution images related to the performance of tissue; this class of imaging technique is known as functional imaging. By comparison, existing technologies such as X-ray and ultrasound produce anatomical images which, only show the structure of tissue. In Seno’s technology, the images are generated based on hemoglobin concentration and its level of oxygenation; the growth of malignant tumors is supported by additional new blood vessels, a process known asangiogenesis, to provide the necessary hemoglobin for that growth.  The resulting increased concentration of hemoglobin, especially that which has given up its oxygen to the cancer cells, is a prime indicator of cancer. Seno’s technology shows this type of functional information. Images are generated without using ionizing radiation (X-rays) or injection of contrast agents.
