The process of spatially aligning two or more images acquired from different devices or imaging protocols is known as multi-modal image registration. As the similarity measure used is one of the most significant aspects of this process, certain measures have been proposed to enhance multi-modal image registration. However, the currently available measures are either not sufficiently accurate or are...
The registration of 3D CT volumes to 2D fluoroscopy video frames has been used in a number of important medical applications such as image guided surgery and kinematic analysis of joints. A major limitation for this type of registration is the computational complexity of the algorithms required to perform the registration. These algorithms present a significant computational burden since they are...
Kinematic analysis of normal and artificial knee joints is an important diagnostic tool for the orthopaedic research community. Abnormal motion in a knee joint gives rise to pain and eventually causes chronic injury. Currently the standard way to measure the motion of bones in a knee joint with high precision is by implanting tantalum beads in the bones prior to imaging using X-ray equipment. This...
2D-3D image registration has become an important tool in many clinical applications such as image-guided surgery and the kinematic analysis of bones in knee and ankle joints. A limitation of this approach is the need to recalculate the voxel values in the 3D volume for every iteration of the registration procedure. In this paper we propose a new 2D-3D image registration algorithm which uses the projected...
3D computed tomography (CT) to single-plane 2D fluoroscopy registration is an emerging technology for many clinical applications such as kinematic analysis of human joints and image-guided surgery. However, previous registration approaches have suffered from the inaccuracy of determining precise motion parameters for out-of-plane movements. In this paper we compare kinematic measurements obtained...
