Biological ultrasonic (US),photoacoustic (PA) and magnetoacoustic (MA) imaging techniques had similar imaging principles and complementary characteristics.Combined US,PA or MA imaging can provide joint images of biological tissues which present complementary information for more comprehensive characterization of tissues in contrast to single imaging technique.The pathological tissues could be precisely located and their morphology and composition could be accurately identified.This review presented current progresses in combined PA-US,MA-US and US-PA-MA imaging techniques,espeically endoscopic imaging,focusing on the technical aspects of integration and their applications in biomedicine.
