Abstract
Disclosed is a probe for medical echography wherein, between the piezoelectric transducers and the backing, there is inserted a half-wave strip at the natural resonance frequency of these transducers, thus enabling the use of the probe in two distinct frequencies, one of which is substantially equal to half the other, and thus providing for ordinary mode B imaging and DFM Doppler imaging with one and the same probe.
