In the paper was presented а comparative analysis of two new approaches for specific noise reduction in medical ultrasound (US) images on the base of 2D Discrete Wavelet and Wavelet Packet Transformations. Some parameters of the wavelet transformations are optimized with the goal to become maximal noise reduction and improve the quality of the diagnostic ultrasound images. They are taken into account by the analysis of two different approaches. Some results of the experiments are presented, which were made by computer simulation in MATLAB environment.
