An interventional device (110) includes an elongate shaft and a transducer strip (112). The transducer strip includes a first edge and an opposing second edge. The first edge and the second edge are separated by a width dimension, and the first edge and the second edge each extend along a length direction of the transducer strip. The transducer strip also includes a piezoelectric transducer (116) that extends along a transducer direction that forms an acute angle with respect to the length direction. The transducer strip is wrapped in the form of a spiral around the elongate shaft of the interventional device such that the piezoelectric transducer forms a band around the elongate shaft. The width dimension is defined such that the adjacent first and second edges of consecutive turns of the spiral abut or overlap one another.
