Surgical Simulation on the GPUSurgical Simulation on the GPU
• Real-time simulation of surgical procedures on congenitally malformed hearts
• Can we reduce mortality rates in complex surgery?
• Scenarios
– Training of novice surgeons
– Preoperative surgical planning of patient-specific procedures

ReconstructionReconstruction
• Morphological models reconstructed from 3D MRI
– Patient-specific morphology
– Possibly enhanced by post-processing if used for educational purposes
– On the model to the right we image a patient with several atrial and ventricular septal defects – i.e. holes between the main chambers of the heart
Technical requirementsTechnical requirements
• Real-time tissue deformation
– The CPU is simply not fast enough
– Use the GPU for general computations instead
• >20-fold acceleration
• The GPU can significantly accelerate computations in a range of medical simulation applications
Dose planning in radiotherapyDose planning in radiotherapy
• CT imaging of neck cancer
• The tumor (arrow) shrinks during treatment
• It will be advantageous to update the dose plan according to the morphological changes
• A deformable registration method (accelerated >30 times on the GPU) is used to calculated the accumulated dose
