Patient 3. (a) The denoised MR image corresponding to US image (b). (c) The probability map based on operator and extracted from denoising MR image. The initial error is estimated around mm by the experts for this patient. In the red box, the operator efficiently detects the sulci also visible in the US image. This case presents a limited field of view while the lesion is large. Moreover, an acoustic shadow is visible on the right lower part of the US image (indicated on the US image by a narrow).
