Abstract: In one aspect, testing apparatus for ultrasound transducers comprising arrays of transducing elements are described herein. In some embodiments, a test apparatus for an ultrasound transducer having a curved transducing element array comprises a block of material permitting propagation of an acoustic signal generated by the transducer, the block of material comprising a transducer receiving surface and a second surface in facing opposition to the receiving surface and forming an acoustically reflective interface with a medium, the second surface comprising a curvature having a center similar to or substantially similar to the center of curvature of the transducer element array when the transducer is coupled to the receiving surface.
