[source in ebook] NCAET_EC_39 DL : 0: In Medical digital images, produced by various imaging devices like x-ray, CT, magnetic resonance imaging (MRI), ultrasound, etc., use for diagnosis of diseases. Ultrasonic imaging is a widely used medical imaging procedure because it is economical, comparatively safe. The main problem during diagnosis is the distortion. These distortions are termed as ‘Noise’. This study focus on one type noise, namely, ‘Speckle Noise’, produced by ultrasonic devices. This paper concentrated to reduce speckle noise and the studies the effect of different filtering techniques for speckle reduction. The paper introduces the speckle reducing anisotropic diffusion (SRAD) method that reduces the noise effectively without loss of original image. The experimental results proved that SRAD gives higher PSNR. The performance of SRAD was superior compared to traditional lee, frost, kaun filter.
