Navigation systems commonly used in neurosurgery suffer from two main drawbacks: (1) their accuracy degrades over the course of the operation and (2) they require the surgeon to mentally map images from the monitor to the patient. In this paper, we i

Multi-Modal Image Registration Based on Gradient Orientations of Minimal Uncertainty

Autor: Tal Arbel, D.L. Collins, Dante De Nigris

Publikováno v: IEEE Transactions on Medical Imaging. 31:2343-2354

In this paper, we propose a new multi-scale technique for multi-modal image registration based on the alignment of selected gradient orientations of reduced uncertainty. We show how the registration robustness and accuracy can be improved by restrict

Publikováno v: International journal of computer assisted radiology and surgery. 11(9)

As an inexpensive, noninvasive, and portable clinical imaging modality, ultrasound (US) has been widely employed in many interventional procedures for monitoring potential tissue deformation, surgical tool placement, and locating surgical targets. Th

Fast and efficient image registration based on gradient orientations of minimal uncertainty

Autor: Dante De Nigris, Tal Arbel

Publikováno v: ISBI

There exist a wide variety of time sensitive contexts (e.g. image-guided neurosurgery (IGNS)), whereby image registration is required to be both fast and accurate if it is to be adopted clinically. Many sampling techniques have been proposed to speed
