Abstract
Objective:Due to the inherent characteristics of medical ultrasound images, the study of B-type ultrasonic medical image filtering technique, you can make the image quality greatly improved.Methods: through tools such as Matlab, for b-mode ultrasonic image Adaptive mean filter, median filter, median filter, wavelet transform, anisotropic diffusion equation filtering;Results: compares the common b-mode ultrasonic filtering algorithms and research.Conclusion:all the filtering method for image signal is enhanced to a certain extent, suppression for noise, too. Mean square error reflects filtering image noise, while attention to detail, keep, for medical ultrasonic images in the hope that is in between the two to achieve an optimal balance.关键词
