A method for the calculation of the impulse response of annular-sectorial (also called annular-segmented) pistons embedded in an infinite rigid baffle is presented. Our calculations are grounded on the Angular Spectrum method following the main features of the theoretical development presented by Guy...
The angular spectrum technique is the standard method for extrapolating ultrasound fields from a data set consisting of point measurements of the pressure field in a single plane 1 . Since the field distribution on any other plane may then, in principle, be predicted via relatively straightforward ...
Compared to the standard of care InSightec ray tracing method, the hybrid angular spectrum method recovered more focal spot intensity at the target and resulted in less focal spot positioning errors. Using improved phase corrections to refocus the focal spot has great relevance for transcranial focused...
The reconstruction of a digital hologram is based on the plane-wave expansion of the diffracted wave fields using Fourier optics (this method is also known as the angular spectrum method). With this method, the object-to-hologram distance can be quite small because the minimum-distance ...
A novel method is proposed for simulating free-space propagation. This method is an improvement of the angular spectrum method (AS). The AS does not include any approximation of the propagation distance, because the formula thereof is derived directly from the Rayleigh-Sommerfeld equation. However,...

A computing simulation routine to model any type of circularly symmetric diffractive X-ray element has been implemented. The wavefield transmitted beyond the diffractive structures is numerically computed by the angular spectrum propagation method to an arbitrary propagation distance. Cylindrical symmetry is...
