1. In a micro-echographic probe for collimation of ultrasonic waves into a deformable surface of a material, the probe having, at one end, a transducer for providing a beam of said ultrasonic waves and, generally at an opposite end, a convex tip for contact with said surface and defining an opening through which said ultrasonic waves enter said deformable surface and material, the improvement wherein:

  • said ultrasonic waves have a frequency equal to at least 20 MHz; and

    said transducer is disposed directly on one end of a principal body that is continuous up to a body tip generally at said convex tip and such that said waves converge in said principal body from said transducer towards a focus in said material.
