Opto-acoustic imaging looks for the presence of tumor neoangiogenesis, new blood vessels produced by malignant tumors to help supply nutrients to and remove wastes from the tumor. Malignant masses cannot grow larger than 2-3 mm without generating neovessels. The Seno laser wavelengths used were selected to enable visualization of relative amounts of oxygenated and deoxygenated hemoglobin within the vasculature and within masses and their surrounding tissues. Inside vessels supplying and draining a malignant tumor, the hemoglobin gives up its oxygen to the rapidly growing cells and becomes deoxygenated.
