This volume explores the cutting edge of image processing within the field of medical imaging. It presents research from the American Association of Physicists in Medicine and the Society of Photo-optical Instrumentation Engineers, focusing on advancements discussed at the February 2001 conference in San Diego. The presented topics include the derivation of expected registration error for point-based rigid-body registration and the methods for registering head CT images to physical space using multiple geometric features.

This collection of papers, presented at a 2001 conference, offers a snapshot of the state of the art in medical imaging processing at the turn of the millennium. The focus on registration techniques suggests a technical audience interested in the foundational algorithms and their practical application in fields like neuroimaging. The inclusion of work from prominent professional societies indicates a peer-reviewed and academically rigorous collection.
