Device and method forbreast cancer diagnosis

An ultrasound device (1) for carrying out a breast diagnostic examination for breast cancer diagnosis comprising two ultrasound probes (10, 20), characterized in that each of said probes (10, 20) comprises a first array (11, 21) of piezoelectric or CMUT transducers with a first nominal frequency (f1) and a second array of piezoelectric or CMUT transducers (12, 22) with a second nominal frequency (f2), said probes (10, 20) being arranged opposite to each other, being configured to rotate along a circular trajectory having for center the midpoint of the segment connecting them and to slide to each other along said straight line connecting them, so that they come in contact with the breast of the patient from diametrically opposite portions, in that said arrays (11, 12, 21, 22) comprise each a plurality of piezoelectric or CMUT transducers, positioned so that acquisitions are carried out on a plane of acquisition orthoqonal to the plane of said circular trajectory, and in that 38 said device is configured to carry out, by moving said probes (10, 20) along said circular trajectory, a plurality of scans relative to a plurality of planes of acquisition (P0, P1 . . . ) passing through said midpoint, orthogonal to said circular trajectory and rotated to each other of an angle (a).
