Denoising 3D ultrasound

What is the most effective filter to denoise a 3D ultrasound image (3 dimensional matrix of a grayscale image)?
I tried:
  • imgaussfilt3
  • ROF filtering
  • fourier ideal filter
  • edge sharpening
  • Wiener filtering
But this doesn't help much.
Does anyone has a suggestion?
Thanks in advance

It's purely depends on, what types of noise presence in the images. Though I can't commnet with surety, those filters may work perfectly without observing the noisy image. It would be better, if you can attach a sample data.
Other way, you may try with some other basics image pre-processisng steps (histeq or adaptivehistEq), then apply those filter (single or successively). I suggest to check the following paper (Index: pubMed) using sparse representation. If the case of speckle noises, look here for review of literature.

Thank you, I will try other image pre-processing steps!
