Comparison of cepstrum-based methods for radial blind deconvolutionof ultrasound images

摘要

This paper compares the performance of seven differentncepstrum-based methods for radial blind deconvolution of medicalnultrasound images. The first is the generalized cepstrum method. Thensecond is the spectral root cepstrum method. These methods have receivednlittle attention so far. The last five methods are all based on thencomplex cepstrum, but different computational techniques in the spatialnand frequency domain are employed. Using in vivo radio frequency datanfrom a clinical scanner, the generalized cepstrum method gave the bestnimages closely followed by the complex cepstrum using phase unwrappingnor polynomial rooting. The complex cepstrum method using higher-ordernstatistics was ranked as low as number five. These results are annimportant guideline for selecting a specific cepstrum-based radialndeconvolution method for implementation in ultrasound scanners
