Sequence slices enhancement of peripheral nerve based on surfacelet transform

Enhancement of nerve sequence slice images is a key step of three-dimensional reconstruction of peripheral nerve. This paper presents a truly multi-scale, multi-directional decomposition method called surfacelet transform for sequence slice images for the reason that low-contrast enhancement effect of nerve slice images is not obvious, the method takes nerve sequence slices as a three-dimensional space-time signal, on the basis of a single picture processing in the traditional transform domain processing, making an improvement, applied to nerves sequence slice CT image enhancement. Experimental data show that this method compared to other methods, can preserve the neurological details of CT images better, achieve high signal to noise ratio and better visual effects.
