Abstract:
1. A method for producing a high frame rate, high resolution and high contrast image, comprising: a) transmitting, using at least one transmitter, a group of signals of energy weighted by single spatial frequency but may be of different phases or linear time delay toward an object to be imaged; b) weighting receive signals from the object with multiple spatial frequencies, or by performing a spatial Fourier transform; c) reconstructing, using an inverse fast Fourier transform element, a two- or three-dimensional image data set from the group of the transmitted signals weighted by the single spatial frequency or linear time delay, and the receive signals weighted with the multiple spatial frequencies or processed by the spatial Fourier transform; and, d) reconstructing the high frame rate, high resolution and high contrast image from the image data set of step c) using a processor.
