Characterization of cells and tissues using a compact GHz ultrasonic imager

Imaging technologies contribute to advances in medical diagnostics and treatment of diseases by facilitating the study of the structure and dynamic behaviors of cells and tissues. This work reports on the use of a monolithic CMOS ultrasonic imager as a platform for visualizing tissues and cells at GHz frequency. The 128 x 128 array of AlN transducers allows for real-time visualization of cells/tissues in dark environments, in addition to the measurement of their mechanical properties.
