  • Patent number: 9433399
    Abstract: An ultrasound diagnosis apparatus according to an embodiment includes a decomposing unit, a diffusion filter unit, an adjusting unit, and a reconstructing unit. The decomposing unit decomposes ultrasound image data into low-frequency and high-frequency decomposed image data at each of a predetermined number of levels, by a multi-resolution analysis. The diffusion filter unit applies a diffusion filter to the low-frequency and high-frequency decomposed image data at the lowest level and applies, at each of the levels other than the lowest, a diffusion filter to data output from the level immediately underneath and to the high-frequency decomposed image data, and also generates edge information for each of the levels. The adjusting unit adjusts a signal level of the high-frequency decomposed image data for each of the levels, based on the edge information. The reconstructing unit obtains corrected data of the ultrasound image data by performing a multi-resolution synthesis.
