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 ...

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.

there is a growing need in the research and clinical medical imaging community for Internet-capable tools that facilitate remote data dissemination and interaction. 3-dimensional (3D)medical imaging datasets typically require special-purpose, non-portable, software to be installed and maintained on each workstation. Internet technologies have potential for improving this.
Both stochastic and direct optimization of similarity metrics have been used in biomedicalimage registration. this paper proposes an adapted tabu search for registration of 2D ultrasound scans to 3D volumes. Accuracy...
