Image restoration system and method

摘要

A system and a method for improving the quality of ultrasound images. The system comprises a processor being configured to subdivide the ultrasound image, determine a deconvolution factor for the ultrasound image and apply the deconvolution factor to the subdivided ultrasound image, resulting in a restored image.

1. A system for improving the quality of an imaging system image, comprising:
an input/output interface configured to receive the imaging system image; a processor in communication with the input/output interface, the processor being configured to:
a) subdivide the imaging system image;b) apply discrete cosine transform (DCT) denoising using a hard thresholding rule;c) apply an iterative expectation-maximisation (EM) regression model;d) estimate the point spread function;e) set the DCT deconvolution factor to the estimated point spread function;f) apply the DCT deconvolution factor to the subdivided image; andg) provide a restored image based on the deconvoluted subdivided image.
