  • Ultrasound imaging method/technique for speckle reduction/suppression in an improved ultra sound imaging system
    Patent number: 9934554
    Abstract: The present invention relates to an improved ultrasound imaging method/technique for speckle reduction/suppression in an ultra sound imaging system in which scan conversion and speckle reduction is performed simultaneously in the scan conversion stage avoiding any kind of conventional interpolation. An improved method for speckle reduction in an ultrasound imaging system and an improved ultra sound imaging system for speckle reduction is provided in the present invention. The method comprises steps of receiving in a processor means raw data samples as an input comprising image signals with noises from a logarithmic amplifier, processing the received image signals for scan conversion and speckle reduction in the processor means so as to get pixel value from the raw data samples and to perform speckle reduction so as to provide speckle filtered output image.
