03 Patient Specific Intervention Planning in CMF Surgery
The aim of this project is to create a single integrated console for planning
complex facial interventions in cranio-maxillo-facial surgery. This new console
will integrate and extend earlier results from Co-Me phases 1 and 2. The work
flow of the new platform will be optimized in close cooperation with surgeons
which are familiar with the currently used state-of-the-art tools. The new
platform will be based on a consistent data flow seamlessly integrating the
different stages from imaging, segmentation, simulation to navigation and thus
eliminate the often cumbersome data transfer between the different application
programs. The amount of manual intervention, currently still necessary for data
segmentation, will be dramatically reduced and novel real-time tissue
simulation techniques will be developed and integrated.
WP 1 - Skull and Soft Tissue Segmentation
This work package aims at developing efficient skull and soft-tissue
segmentation methods using CT and special MR sequences.
WP 2 - Assessment of Structural and Mechanical Properties of Skeletal Muscle with MRI
Besides the in-vivo assessment of the mechanical tissue properties using MR
elastography (non-invasive method to measure the stiffness and strain of soft
tissue), specific MR sequences that optimize soft-tissue contrast are developed
in this work package.
WP 3 - Characterization of the Mechanical Response of Soft Facial Tissue
Methods to measure the mechanical properties of the tissue (using an aspiration
device) and to characterize the phenomenological equations of the non-linear
mechanical behavior are the research focus of this work package.
WP 4 - Soft Tissue Modeling for CMF Interventions
A hybrid approach modeling facial tissue deformations in real-time is developed
in this work package. The approach combines a physically-based soft tissue
modeling technique specifically tailored for CMF with a highly accurate
pre-computed FEM library of deformations that is driven by an interpolation
component for interactive and fast simulation of highly detailed face models
while retaining realism.
WP 5 - Robot-Guided Laser Osteotomy
This work package deals with issues related to robot-guided laser osteotomy to
allow for complex cutting geometries while controlling the depth in real-time.
