The paper presents a general non-rigid body representation suitable for physically-based modeling of deformations of inhomogenious objects. The reliability of the obtained results is demonstrated on real medical data sets-CT an MR scans of human brain.
Digital image warping is a growing branch of image processing that deals with geometric transformation techniques. A geometric transformation is an operating that redefines the spatial relationship between points in an image. Physically based modeling is a field strongly attracting research interest in recent years. A physically based model includes… (More)
This paper discusses the transformation of computed tomography (CT) and magnetic resonance (MR) images, which maps the stereotactic volumetric cube of one examination to another. There are some mathematical problems connected with the present method. This approach provides a better visual detection and localization of the target point for the neurosurgeon… (More)
