Giga-Hertz ultrasonic microscopy: Getting over the obscurity: A short review on the biomedical applications
Physics in Medicine(2020)
摘要
Scanning acoustic microscopy in the gigahertz regime (GHz-SAM) has long been a versatile and complementary micro and nanoscopic imaging and analysis tool. Nevertheless, it remained obscured to some extent, compared to its counterparts, such as atomic force microscopy (AFM), despite its unique capability of subsurface analysis. Some current research in our lab at Georgia Tech Lorraine is devoted to the use of the subsurface imaging of GHz-SAM in biological tissues, which has been restricted, mostly, to very stiff materials, in terms of acousto-mechanical impedance, such as metals.
