Abstract

Multiresolution decomposition of image data before scan conversion processing is hierarchically performed, low-frequency decomposed image data and high-frequency decomposed image data with first to n-th levels are acquired, nonlinear anisotropic diffusion filtering is performed on output data from a next lower layer or the low-frequency decomposed image data in a lowest layer, and filtering for generating edge information on a signal for every layer is performed from the output data from the next lower layer or the low-frequency decomposed image data in the lowest layer. In addition, on the basis of the edge information on each layer, a signal level of the high-frequency decomposed image data is controlled for every layer and multiresolution mixing of the output data of the nonlinear anisotropic diffusion filter and the output data of the high-frequency level control, which are obtained in each layer, are hierarchically performed.

Description

technical field

[0001] The present invention relates to an ultrasonic diagnostic device, an ultrasonic image processing device, and an ultrasonic image processing method that transmit ultrasonic waves into a subject and obtain diagnostic information in the subject based on reflected waves from the subject, and particularly relates to small data contained in image data. Speckle removal. Background technique

[0002] In ultrasonic diagnosis, the pulse of the heart and the movement of the fetus can be displayed in real time by a simple operation of attaching an ultrasonic probe to the body surface, and the safety is high, so repeated examinations can be performed. In addition, the scale of the system is smaller than that of other diagnostic equipment such as X-ray, CT, and MRI, and it can be easily performed on the bedside for inspection, which can be said to be a simple diagnostic method. Ultrasonic diagnostic equipment used in this ultrasonic diagnosis differs depending on t...
