A method for quantitatively evaluating the expected ultrasonic inspectability of a designed part using ray tracing. First, a model of a part imported. Materials having different indices of refraction are selected for the part and an acoustic coupling medium. Then the following structures and positional relationships are defined: an ultrasonic transducer array comprising a plurality of elements, a position of the acoustic coupling medium between the transducer array and the part, and a plurality of positions of a transmit aperture relative to the part. For each defined position of the transmit aperture, a path of a respective ray is traced from a center of the transmit aperture through the part and then to a respective receive location on the transducer array. Also, a respective value of an inspectability margin is calculated based at least in part on a respective distance between a center of the receive aperture and the respective receive location. Each value of the inspectability margin is compared to a threshold value.
