Description: Ultrasound Speckle Reduction Using Coded Excitation and Pulse Compression
Ultrasound images are riddled with system dependent imperfections called speckle (multiplicative noise). In ultrasonic imaging, detection of small lesions could be difficult because the effects of speckle may mask the visibility of these small targets. Therefore, the purpose of this project is to decrease speckle while maintaining some of the key salient features in the image. Images of tissue-mimicking phantoms will be created using Field II [1-2] in MATLAB (Natick, MA). Image quality metrics such as speckle signal-to-noise ratio (sSNR) [3] and contrast-to-noise ratio (CNR) [4] will be used to quantify improvements in image quality after various despeckling filters have been applied.

Description: 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. Platform: |
