Projection and Reconstruction-Based Noise Filtering Methods in Cone Beam CT, reduce the noise level and preserve the diagnostic value of the low-dose images. In this work, six variants of Gaussian and bilateral filters are applied in both projection and reconstruction domain. Our comparison of noise reduction and image resolution shows that 2D and 3D bilateral filtering in

The SIP-NVC-Wizard,em. Surgical intervention planning (SIP) for NVC enables a comprehensive spatial understanding of the patient specific anatomy. Specifically, brainstem, vessels and nerves are segmented in NVC SIP. To support segmentation for NVC SIP, we propose a wizardbased user guidance. The SIP-NVC-Wizard guides

Assessment of Electrode Displacement and Deformation with Respect to Pre-Operative Planning in Deep this paper a method is proposed to align models of deep brain stimulation electrodes that are automatically extracted from post-operative CT imaging in a common coordinate system utilizing the planning data as reference. This enables the assessment of electrode displacement and deformation over the

Passive 3D Needle Tip Tracking in Freehand MR-Guided Interventions with Needle Model Visualization,passive needle tip tracking in 3D is presented. For a true- FISP sequence, it is shown that proper k-space sub-sampling and signal processing allow for an accurate estimation of the needle tip position. A reduction in scan time is achieved by drastically reducing the number of measurements. The calc
