We propose a method for estimating intrasurgical brain shift for image-guided surgery. This method consists of five stages: the identification of relevant anatomical surfaces within the MRI/CT volume, range-sensing of the skin and cortex in the OR, rigid registration of the skin range image with its MRI/CT homologue, non-rigid motion tracking over time of cortical range images, and lastly, interpolation of this surface displacement information over the whole brain volume via a realistically…

In this paper, we propose a fast multistage hybrid algorithm for 3D segmentation of medical images. We first employ a morphological recursive erosion operation to reduce the connectivity between the

Correlation of preoperative MRI and intraoperative 3D ultrasound to measure brain tissue shift

A system that provides real-time freehand 3D ultrasound reconstruction at a reduced resolution that provides the operator with the necessary feedback to maintain a constant freehand sweep-rate and also ensures that the sweep covers the desired anatomical volume.

Brain shift estimation in image-guided neurosurgery using 3-D ultrasound

Intraoperative brain deformation is one of the most important causes affecting the overall accuracy of image-guided neurosurgical procedures. One option for correcting for this deformation is to

Ultrasound/MRI Overlay with Image Warping for Neurosurgery

2D and 3D image overlay tools which allow interactive, real-time visualization of the shift as well as software that uses homologous landmarks between the ultrasound and MRI image volumes to create a thin-plate-spline warp transformation that provides a mapping between pre-operative imaging coordinates and the shifted intra-operative coordinages.

A morphological recursive erosion operation is introduced to reduce the connectivity between the heart and its neighborhood, then an improved fast marching method is employed to greatly accelerate the initial propagation of a surface front from the user defined seed structure to a surface close to the desired heart boundary.

Although now in extensive clinical use, IGS is often currently perceived as an intrusion into the operating room, and must evolve towards becoming a routine surgical tool, but this will only happen if natural and intuitive human interfaces are developed for these systems.



Recovering the Position and Orientation of Free-Form Objects from Image Contours Using 3D Distance Maps

The combination of the authors' problem formulation in 3D, their computation of line to surface distances with the octree-spline distance map, and their simple minimization technique based on the Levenberg-Marquardt algorithm results in a method that solves the 3D/2D matching problem for arbitrary smooth shapes accurately and quickly.

This work employs the new geometric active contour models, previously formulated, for edge detection and segmentation of magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound medical imagery, and leads to a novel snake paradigm in which the feature of interest may be considered to lie at the bottom of a potential well.
