Method for exploring and displaying tissues of human or animal origin from a high frequency ultrasound probe where high frequency ultrasound waves are focussed to a penetration distance of between 20mm and 30mm

摘要

Describes a method for exploring and displaying tissues of human or animal origin which consists in: positioning an ultrasound probe (1) carried by a head steered by means of a three-dimensional positioning system (2), in particular computer-controlled, perpendicular to the tissue structure; controlling the probe such that it generates convergent high frequency ultrasound wave beams (of the order of *= 50 MHz), said waves being focused at a predetermined zone of the tissues, over a penetration distance ranging between 20 and 30 mm; scanning the tissue structure by the computer-controlled (3) positioning system (2), by carrying out parallel acquisition, by the computer (3) of signals reflected by the tissue structure; carrying out various signal processing operations on the data derived from scanning, to improve the reproduction of data and facilitate interpretation thereof by the practitioner.
