Abstract:
1. An imaging apparatus comprising: a container for a liquid; a transmitter for transmitting wavefield energy into the liquid and a tissue appendage of a body of a mammal; a device holding the tissue appendage stationary relative to the liquid in the container; a receiver to receive wavefield energy transmitted through the liquid and the tissue appendage; and an image renderer to process the received wavefield energy in an inverse scattering parabolic propagation step to render therefrom an image of the tissue appendage; wherein the wavefield energy that is received by the receiver is transmitted from the transmitter and has a wavelength in the liquid in the container corresponding to a corresponding maximum temporal frequency; and the image renderer performs an inverse scattering parabolic propagation step that is accelerated in speed by employing a computational pixel size that is greater than one half of the wavelength of the corresponding maximum temporal frequency.
