ABSTRACT
Medical ultrasound imaging suffers from poor resolution due to its inherit imaging mechanism.In order to obtain the important diagnostic image in detail,restoration procedure needs to be performed.However,in practical ultrasound imaging,it's difficult to demonstrate the degradation process in detail.Therefore,blind image deconvolution is applied to estimate the original image from the degraded image with unknown point spread function or little available prior knowledge.In this paper,the main algorithms of medical ultrasound image restoration based on blind deconvolution are reviewed and classified into two categories,priori or joint with the image,according to the identification methods,and the basic theories and improved methods are analyzed and discussed.Finally,the future directions in blind restoration for medical ultrasound images are proposed.
