Rigid and elastic registration for coronary artery IVUS images.

BACKGROUND Intravascular ultrasound (IVUS) has been widely used in diagnosis and interventional treatment of cardiac vessel diseases. The coronary artery IVUS images are usually polluted by motion artifacts caused by cardiac motion, pulsatile blood and catheter twist during continuous pullback acquisition. OBJECTIVE Strategies for rigid and elastic registration of coronary artery IVUS studies...

Non-rigid Registration of Vessel Structures in IVUS Images

We present a registration and retrieval algorithm of medical images. Our algorithm is oriented in a general fashion towards gray level medical images of non-rigid bodies such as coronary vessels, where object shape information provide poor information. We use rich descriptors based on both local and global (contextual) information, and at the same time we use a cooperative-iterative strategy in...

Compensation of brain shift during surgery using non-rigid registration of MR and ultrasound images

Background: Surgery and accurate removal of the brain tumor in the operating room and after opening the scalp is one of the major challenges for neurosurgeons due to the removal of skull pressure and displacement and deformation of the brain tissue. This displacement of the brain changes the location of the tumor relative to the MR image taken preoperatively. Methods: This study, which is done...

Rigid Medical Image Registration for Monomodal Images

Image registration is the fundamental task used to match two or more partially overlapping images taken at different times, from different sensors, or from different viewpoints. It is a technique useful in integrating information from different sources. Image registration techniques can be based upon image gray-scale or image features. Feature based registration gives a coarse result. Thus, usi...

Retrieval of IVUS images using contextual information and elastic matching

We present a content-based image retrieval system of medical images of bodies with high elasticity, that is, high interand intrasubject variability in shape. The system is based on a rich feature space that is able to describe all the relevant aspects of an image, including local, global, and contextual information. For including relative spatial relations between the structures (i.e., contextu...
