Principal Component Analysis Based Hybrid Speckle Noise Reduction Technique for Medical Ultrasound Imaging

Abstract: Ultrasound imaging is the safest and most widely used medical imaging technique available today. The main disadvantage of ultrasound imaging is the presence of speckle noise in its images that may obscure pathological changes in the body and makes diagnosis more challenging. Therefore, many techniques were proposed to reduce speckle and improve image quality. Unfortunately, variations of their performance with different scan parameters and due to their methodologies make it hard to choose which one to adopt in… Show more

“…Wavelet-based methods primarily operate using wavelet shrinkage with different wavelet families and levels of composition [21] , [22], [23] , [24]. Hybrids incorporating elements from these methods have also been introduced [25] , [26], [34], [35]. Other approaches include methods that use a human visual system model to reduce the appearance of noise in ultrasound images [36], and methods involving deep learning using convolutional neural networks to build despeckling models from training custom-designed networks [37], [38].…”
