A framework for virtual reality based training of puncture interventions is presented. The system uses a haptic device with six degrees of freedom (6DOF) to enable realistic force sensations during needle insertions into virtual patients. A manifold of different visualization techniques gives new insights into the anatomy of the punctured region. The 3D… (More)
Purpose To evaluate the ability of velocity encoded (VENC) magnetic resonance imaging (MRI) to identify patients with diastolic dysfunction in comparison with Doppler-echocardiography.
