Volumetric cone-beam CT (CBCT) images are acquired repeatedly during a course of
radiation therapy and a natural question to ask is whether CBCT images obtained earlier in …

We propose an ischemic stroke detection system with a computer‐aided diagnostic ability
using a four‐step unsupervised feature perception enhancement method. In the first step …

Multi-phase dynamic contrast-enhanced magnetic resonance imaging image registration
makes a substantial contribution to medical image analysis. However, existing methods (eg …

Ischemic stroke is a condition which causes death of brain cells due to lack of blood supply
and hence stops normal brain functioning. Due to finite academic studies of ischemic stroke …

In order to protect the image contents, many reversible medical image watermarking
schemes have been proposed, although reversibility guaranteed the lossless of the cover …

Multi-modal image registration plays an increasing role in diagnosis, surveillance, and
treatment of disease. This paper proposes a new registration measure, called contour and …

It is highly desirable that the complementary information of computed tomography (CT) for
dose planning and magnetic resonance imaging (MRI) for accurate organ delineation …

Most registration algorithms for medical images may suffer from slow convergence and
sensitivity to initialization. In this paper, we propose an efficient gradient-based algorithm for …

A robust and fast hybrid method using a shell volume that consists of high contrast voxels
with their neighbors is proposed for registering PET and MR/CT brain images. Whereas …

A new coarse-to-fine strategy was proposed for nonrigid registration of computed
tomography (CT) and magnetic resonance (MR) images of a liver. This hierarchical …
