Intensity-Based 2D-3D Spine Image Registration Incorporating One Fiducial Marker
نویسندگان
چکیده
In this paper, we propose a hybrid similarity measure for 2D-3D image registration that is a weighted combination of an intensitybased image similarity measure and a point-based measure incorporating a single fiducial marker. We evaluate its accuracy and robustness using gold-standard clinical spine image data. The use of one fiducial marker substantially improves registration accuracy and robustness.

Intensity-based 2D-3D spine image registration incorporating a single fiducial marker.
RATIONALE AND OBJECTIVES The two-dimensional (2D)-three dimensional (3D) registration of a computed tomography image to one or more x-ray projection images has a number of image-guided therapy applications. In general, fiducial marker-based methods are fast, accurate, and robust, but marker implantation is not always possible, often is considered too invasive to be clinically acceptable, and en...
متن کاملEvaluation of Intensity-Based 2D-3D Spine Image Registration Using Clinical Gold-Standard Data
In this paper, we evaluate the accuracy and robustness of intensity-based 2D-3D registration for six image similarity measures using clinical gold-standard spine image data from four patients. The goldstandard transformations are obtained using four bone-implanted fiducial markers. The three best similarity measures are mutual information, cross correlation, and gradient correlation. The mean t...
متن کاملA Feasibility Study on Mutual Information based Set-up Error Estimator for Radiotherapy
We have investigated a fully automatic set-up error estimation method that aligns DRRs (Digitally Reconstructed Radiographs) from a 3D planning CT image onto 2D radiographs that are acquired in a treatment room. We have chosen a MI (Mutual Information)-based image registration method, hoping for robustness to intensity differences between the DRRs and the radiographs. The MI-based estimator is ...
متن کاملEffective One Step-iterative Fiducial Marker-based Compensation for Involuntary Motion in Weight-bearing C-arm Cone-beam CT Scanning of Knees
We previously introduced three different fiducial marker-based correction methods (2D projection shifting, 2D projection warping, and 3D image warping) for patients’ involuntary motion in the lower body during weight-bearing Carm CT scanning. The 3D warping method performed better than 2D methods since it could more accurately take into account the lower body motion in 3D. However, as the 3D wa...
متن کاملFiducial Registration from a Single X-Ray Image: A New Technique for Fluoroscopic Guidance and Radiotherapy
Fiducial registration is useful both in applications where other registration techniques have poor performance and for validation of new registration techniques. Registration of 3D CT or MR images to 2D X-ray images is particularly difficult, in part because automated contour extraction from 2D images is not yet well solved and in part because of the considerable computational expense in matchi...
