Abstract
A high frequency ultrasonic quantitative characterization of the poros ity of biological cements for the fixation of prosthetic components ha s been realised. The images were acquired with a C-Scan system using a focused 50 MHz transducer. The images were treated by a histogram pro cessing technique associated with a segmentation algorithm. The use of this system has allowed us to demonstrate that a decrease in porosity could be obtained by a polymerization under a high power insonificati on at 500 kHz.
