A method and device are provided for determining a mode of detection of an element that reflects ultrasonic waves, wherein it comprises at least the following steps: For each point P of a given volume Zr, determining an ultrasonic field value A(P) for N emitter-receiver pairs (i, j) and for one detection mode m, computing a number of reflections of the wave where with {right arrow over (n)}(P) the normal formed by the 'forward' direction {right arrow over (d)}and the 'backward' direction {right arrow over (d)}of the ultrasonic wave emitted and reflected by the reflecting element, computing the energy value E(P,{right arrow over (n)}) for each point P of the zone Zr, with {right arrow over (n)} and for a plurality of modes m comparing the obtained energy values E(P,{right arrow over (n)}) to one or more threshold values Es, selecting the one or more energy values that meet the one or more threshold-value conditions, and deducing a mode to be used to construct a representation of the reflecting element.
