Description

Geometrical optics approximation [1,2] provides good prediction of the field generated by an ultrasonic angle probe. However, it requires integration over the aperture of an ultrasonic transducer constituting the ultrasonic angle probe to calculate the field, and so it can not be applied directly to image reconstruction using synthetic aperture focusing technique [3,4].
