"Ultrasound in Medicine - Physics, transducers, instruments and applications"

This talk will address current developments of ultrasound biomicroscopy (UBM) in the
Biomedical Engineering Program at the Federal University of Rio de Janeiro. UBM is a
high-frequency (20-100 MHz) pulse-echo ultrasound approach for imaging living
biological tissues with near-microscopic resolution. It is similar to a conventional B-
mode imaging instrument used for medical diagnosis. The main difference resides on the
ultrasound high frequency used with the UBM system, 40 or 50 MHz in the present case.
Applications to be presented include in vitro images of human skin tumors and of the
colon from small animal (rat and mouse) models for induced colitis and tumors.
