Limited diffraction broadband phased array transducer with frequency
controlled two dimensional aperture capability
摘要:
A transducer array and method for medical imaging which produces an ultrasound beam upon excitation, the transducer array including a plurality of transducer elements, each of said transducer elements having a first surface facing a region of examination when the transducer is in use and a second surface opposite of the first surface wherein the second surface faces away from the region of examination when the transducer is in use, said second surface is concave in an elevation direction, and a focusing lens disposed on the first surface of each element.
