Biomedical Data Visualization
FEKT-FVIZAcad. year: 2017/2018
The course is oriented to knowledge on computer graphics applied to biomedical data. The main focus is visualization of 3D image data acquired using magnetic resonance imaging, CT tomography, PET and SPECT. It is the use of OpenGL methods for basic graphic primitives and creating of 3D scenes. Furthermore, methods for visualization of higher-dimension data are included.
Learning outcomes of the course unit
Former student is able to:
- Describe color spaces in computer graphics
- Describe basic principles of image compression
- Describe principles of 3D scene creation
- Create basic graphic primitives in OpenGL
- Describe light model in 3D scenes
- Describe methods of 3D images creation from volume data (CT, MRI)
- Modify properties of OpenGL rendering
The subject knowledge of programing and algorithms on the Bachelor´s degree level is requested. Knowledge and the ability to use cycles for, while, structures if, switch-case, basic variables data types and basic image processing methods.
