Characterizing the performance of image segmentation approaches has been a persistent challenge. Performance analysis is important since segmentation algorithms often have limited accuracy and precision. Interactive d...

We have developed a system for the 3-D localization of anatomical structures without the need for surgical exposure by using multiple-view fluoroscopy images. In this paper, we describe the system and evaluate its app...

Cardiovascular diseases often result in reduced blood perfusion of the myocardium (MC). Recent advances in MR allow fast recordingof contrast enhanced myocardial perfusion scans. For perfusion analysis the myocardial boundaries must be traced. Currently this is done manually. In this paper a method for automatic detection of the myocardial boundaries is proposed.
computer-based techniques for the simulation of craniofacial surgical procedures and for the prediction of the surgical outcome have been shown to be very useful. However, the assessment of the accuracy of the simulat...

In this work, we propose a new subdivision of intensity-based non-rigid registration algorithms composed of two classes: Standard Intensity Based (SIB) algorithms. In these algorithms, the same transformation is used to compute the intensity similarity measure while being constrained to remain smooth.

An osteoid osteoma is a small, benign, active, painful osteoblastic bone lesion. To effect a cure the entire nidus must be removed, because residual nidus is associated with recurrence of the osteoid osteoma [2]. the technical objective of this work was to perform minimally invasive excision of osteoid osteoma by means of computer-assisted guidance technology. the principal technical hurdle to be overcome was the difficulty of registering the surface of a long bone with minimal surgical exposure.
