Abstract
A tissue characterization device is provided comprising means for transmitting high carrier frequency ultrasonic pulses to the tissues, means for receiving and converting the echos into high frequency electric signals and means for storing said electric signals with a sampling frequency sufficient for the high frequency information which they contain to be correctly recorded, further comprising means for reading the stored information at a rate less than the sampling frequency and such that the high frequency spectrum is transposed into the range of audible frequencies and means for converting the transposed spectrum into a sound signal.
