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.
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...

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.
This paper introduces the concept of structured deformable model and presents its application to 3D medicalimage analysis. A structured deformable model is composed of a group of basic shape elements. A generic model...
