Abstract

The invention discloses a method for the multiresolution anisotropic diffusion filtering real-time processing of ultrasonic images. Aiming at the characteristics of multiresolution anisotropic diffusion filtering image processing algorithms such as large calculation amount and low processing speed, the method relies on Intel hardware and development technology, adopts a blocking and clipping mask method, ensures the undistortionless of the image information, suppresses the speckle noises in the image, increases image processing speed, and is used in an ultrasound imaging system to optimize the processing speed of the display data of ultrasonic scan images.

Description

technical field [0001] The invention relates to ultrasonic imaging technology, in particular to digital image processing technology in ultrasonic imaging technology, especially a method and device for real-time processing of ultrasonic images. Background technique [0002] Such as figure 1 As shown, a typical ultrasound imaging system mainly includes a main controller, a probe, a beamformer, a DSC (Digital Scan Converter, digital scan conversion) module and a display. Under the control of the main controller, the probe emits ultrasonic waves, and after a certain time delay, it receives the ultrasonic signals reflected from the tissue. The beamformer focuses, apodizes, filters, and detects the reflected echo signals of each channel to obtain the scanning echo envelope signal, and then through the DSC module, the signal is converted into image data that can be displayed by the display, and finally output by the display. [0003] Due to the limited spatial resolution of ultra...
