Micro-echographic probe for ultrasound collimation through a deformable surface
First Claim
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.

Abstract
The present invention relates to a micro-echographic probe for ultrasound collimation through a deformable surface. The probe comprises at one end an ultrasonic wave beam transducer, disposed, for example, in the form of a spherical cap, so that said beam converges in a focus (A), which focus is also that of the other end of the monolithic body and which is the contact tip, so that the beam which penetrates in the body to be analyzed is collimated. The ultrasonic waves are preferably at a frequency equal to at least 50 MHz.
