Robust Automated Registration of Wrist Bones Using Tissue Classification and Distance Fields (2007)
G. Elisabeta Marai, David H. Laidlaw, Joseph J. Crisco
TRANSACTIONS ON MEDICAL IMAGING, VOL., NO., DATE 2 We present an intra-subject method for automated registration of wrist bones from computed to-mography (CT) volume images. The method makes possible...

Abstract Objective Mechanical loading of cartilage influences chondrocyte metabolism and gene expression. The gene encoding type X collagen is expressed specifically by hypertrophic chondrocytes and...
A Kinematics-Based Method for Generating Cartilage Maps and Deformations (2006)
G. Elisabeta Marai, Joseph J. Crisco, David H. Laidlaw
Abstract — We present a non-invasive method for estimating individual-specific cartilage maps directly from in vivo kinematic data and computed tomography (CT) volume images, and a novel algorithm...

ABSTRACT: Patients with a malunited distal radius often have painful and limited forearm rotation, and may progress to arthritis of the distal radioulnar joint (DRUJ). The purpose of this study was...
Super-Resolution Registration Using Tissue-Classified Distance Fields (2006)
G. Elisabeta Marai, David H. Laidlaw, Joseph J. Crisco
Abstract—We present a method for registering the position and orientation of bones across multiple computed-tomography (CT) volumes of the same subject. The method is subvoxel accurate, can operate...

Estimating joint contact areas and ligament lengths from bone kinematics and surfaces (2004)
G. Elisabeta Marai, David H. Laidlaw, Stuart Andrews, Cindy M. Grimm, Joseph J. Crisco
Abstract—We present a novel method for modeling contact areas and ligament lengths in articulations. Our approach uses volume images generated by computed tomography and allows the in vivo and...
Constructing 2D curve atlases (2000)
Thomas B. Sebastian, Joseph J. Crisco, Philip N. Klein, Benjamin B. Kimia
We present an approach to computing a curve atlas based on deriving a correspondence between two curves. This correspondence is based on a notion of an alignment curve and on a measure of similarity...
Constructing 2D Curve Atlases (2000)
Thomas B. Sebastian, Joseph J. Crisco, Philip N. Klein, Benjamin B. Kimia
1 Introduction This paper presents a method to construct the average for 2D shape outlines (curves) using their intrinsic properties. A computational framework for constructing an average curve and...
