Hand–eye calibration using a target registration error model

Surgical cameras are prevalent in modern operating theatres and are often used as a surrogate for direct vision. Visualisation techniques (e.g. image fusion) made possible by tracking the camera require accurate hand-eye calibration between the camera and the tracking system. The authors introduce the concept of 'guided hand-eye calibration', where calibration measurements are facilitated by a ...

Fiducial registration error and target registration error are uncorrelated [7261-1]

Image-guidance systems based on fiducial registration typically display some measure of registration accuracy based on the goodness of fit of the fiducials. A common measure is fiducial registration error (FRE), which equals the root-meansquare error in fiducial alignment between image space and physical space. It is natural for the surgeon to regard the displayed estimate of error as an indica...

A Theoretical Comparison of Different Target Registration Error Estimators

Estimation of target registration error (TRE), a common measure of the registration accuracy, is an important issue in computer assisted surgeries. Within the last decade, several new approaches have been developed to estimate either the mean squared value of TRE or the distribution of TRE under different noise conditions. In this paper, we theoretically demonstrate that all the proposed algori...

Target Registration Error in Point-based Rigid-body Registration: a Worst-case Analysis

The model has to be evaluated in terms of accuracy, robustness and speed. In a first evaluation, sequences of anatomic structures were used. Accuracy and robustness were evaluated by registering reconstructed point clouds with a polygon model from a laser scanner. The first results indicated that the surface model is reconstructed with millimeter precision. An important criterion for the usabil...

Submillimetric target-registration error using a novel, non-invasive fiducial system for image-guided otologic surgery.

OBJECTIVE Otologic surgery is undertaken to treat ailments of the ear, including persistent infections, hearing loss, vertigo, and cancer. Typically performed on otherwise-healthy patients in outpatient facilities, the application of image-guided surgery (IGS) has been limited because accurate (<1 mm), non-invasive fiducial systems for otologic surgery have not been available. We now present su...
