Chair for Computer Aided Medical Procedures & Augmented Reality | wwwnavab. cs. tum. edu Motivation Development of an interface for visualization and navigation in 3 D Existing means proofed to be insufficient in certain aspects Integration of all mandatory features into one interface (widget) Realignment of image data for further use (segmentation, diagnostics, …) Examination of requirements CAMP | Department of Computer Science | Technische Universität München | 22 January 2022 3

Chair for Computer Aided Medical Procedures & Augmented Reality | wwwnavab. cs. tum. edu The given environment Medical Imaging & Visualization Environment developed as Lab Course SS 2004 Consists of GUI to show an arbitrary number of Slice and Volume Renderers Slice View: visualization of the three orthogonal slices in one view each and one view merged CAMP | Department of Computer Science | Technische Universität München | 22 January 2022 4

Chair for Computer Aided Medical Procedures & Augmented Reality | wwwnavab. cs. tum. edu Project definition Advanced visualization system based on common 3 -Slice view Use of given interface developed in Lab Course SS 2004 Adapt Slice View to requirements Implementation of new features into the enviromnent CAMP | Department of Computer Science | Technische Universität München | 22 January 2022 5

Chair for Computer Aided Medical Procedures & Augmented Reality | wwwnavab. cs. tum. edu Project specification new features Rigid transformations in the view Particular: Alignment of human heart CT data along the heart’s main axis Integration into FLTK Widgets Ability to display reference set of data, add fading slider Feature for MPR-Thickness-Value and MIP-Mode Transparency (Alpha-Blending, …) Eventual volume rendering & 3 D Texture Slice Rendering CAMP | Department of Computer Science | Technische Universität München | 22 January 2022 6

Chair for Computer Aided Medical Procedures & Augmented Reality | wwwnavab. cs. tum. edu Rigid transformation to set heart axis Task: Integrate feature to rotate slices to align CT-Slice renderers orthogonally to human heart axis Mandatory for cardinal diagnostics Rather user unfriendly implementations in given environments Based on discussion with S. Nekolla, Nuklearmedizin RDI Also needed for alignment of volume for registration! CAMP | Department of Computer Science | Technische Universität München | 22 January 2022 7
