Changes in the sac and coil mass over time were visualized using model registration techniques and quantified using volume calculations.All 8 of the coiled aneurysms with major recurrence had significant aneurysm sac growth (15% to 102% increase in volume), independent of change in coil volume.
Healthy knee kinematics during dynamic full flexion were evaluated using 3D-to-2D model registration techniques.
In this study, 3D-to-2D model registration techniques have been used to measure healthy knee kinematics during dynamic full flexion.
3D-to-2D model registration techniques [ 1– 4] and MRI-based methods [ 5– 9] are used for assessing 3D knee kinematics without implants.
The purpose of this study was to observe healthy kinematics during full flexion in a lunge using 3D-to-2D model registration techniques.
Three-dimensional kinematics was analyzed by fluoroscopic examinations of subjects using a single-plane model-image registration technique.
Digitally reconstructed radiographic images were used for 3D-to-2D model-to-image registration technique.
However, no studies have employed 3D-to-2D model-to-image registration technique to analyze in vivo healthy hip kinematics.
The 3D positions and orientations of the pelvis and femur in movement cycle were determined by 3D-to-2D model-to-image registration technique using image correlations.
The purposes of this study were to evaluate kinematics of healthy hips during gait, squatting, chair-rising, and twisting by 3D-to-2D model-to-image registration technique.
