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.
