Abstract
Apparatus for producing image data representing a specimen being imaged using ultrasound includes a processor and memory. The processor receives input data representing output from an ultrasound probe, and performs an iterative algorithm on the input data until a converged estimate of the mean of the distribution of the image data is reached. This estimate is used to produce output image data for display. The algorithm uses a first matrix that is dependent upon attributes of the probe and upon the way in which the input data was produced, and a second matrix that is the inverse of the sum of: a positive scalar matrix having the same dimensions as the first matrix, and the product of a Hermitian transpose of the first matrix and the first matrix. One step of the algorithm uses the second matrix as a preconditioner.
