Method and system for guiding a user holding an ultrasound observation probe in one hand towards a pre-recorded acoustic window.

Abstract

Method (100) comprising the following steps: placing (101) a support to hold an object (3) comprising markers in a predetermined position and orientation in a reference frame; acquiring (102) an image; determining (103) the reference frame from the markers by image processing; determining (104) the coordinates of a vertex of a polygon (P) placed in a plane transverse to the recorded direction (DE) of the probe; displaying (105) the image; projecting (106) onto the image the vertex of a polygon (P); determining (107) the current position (PA) and the current direction (DA) of the probe (1) in the reference frame; determining (108) the coordinates in the reference frame of the vertex of the polygon (P) placed in a second plane transverse to the current direction of the probe; projecting (109) the vertex onto the image; bringing (110) the probe into a new current position and a new current direction.
