Speckle noise reduction methods in cardiac cycles

Abstract

Speckle noise is omnipresent in imagistic and is an important problem in imagistic because it is the main source of noise in echography and echocardiography images and it should be reduced without affecting the image features. In spite of wider study dealing to speckle noise removal, until now there is no comprehensive method that covers all the constraints. In this study, three techniques were used for despeckling in echocardiography images along cardiac cycles for apical two chamber view (A2C), apical four chamber view (A4C), parasternal long axis view (LAX), and parasternal short axis view (SAX) and their results were compared. To assess the performances of filters, the correlation coefficient (CoC) was used. Following this analysis, the proper filtering method is recommended.
