10 A generalised approach towards functional modeling of human articulations

		Visualization of extreme hip motion with skin, bone, cartilage and ligaments

It is possible to reconstruct or extract 3D surface elements from different kinds of modalities to enable a realistic 3D visualisation. Functional Modelling is increasingly necessary for pre-operative planning and intra-operative guidance. In order to fulfil these needs, 3D functional modelling has to be coupled with 3D surface modelling, cinematic joint motions, motion capture and acquisition, material properties, planning system and inter-patient registration methods.

The main idea is to individualise a 3D model of a hip to the patient. At each stage of the development, 3D models will be compared and validated with available medical information or clinical experiments. For example, dynamic MR images of patients will be used to evaluate the accuracy of the individualised virtual hip in motion.

From MR images to generic models

Creation of generic, animatable models of the male and female hip from MR images

Individualised reconstruction

Reconstruction of an individualised hip from multi-modal patient data.

Simulation of soft tissues deformation

Acquire dynamic MRI, optical motion capture and physiological measurements to parameterise a biomechanical model of the hip joint to simulate the deformation of soft tissues.

Development of natural 3D interfaces

The 3D interfaces with stereovision allow to see the status of the anatomy of the individual patient based on 2D MR images.
