Course description
Acquisition of biomedical images:
digital photography and video cameras, optical techniques, microscopic techniques, X-ray imaging, computed tomography, magnetic resonance imaging, ultrasound, emerging imaging technologies – physical principles, acquisition technologies and geometries, implementations and characteristics of imaging devices, image artefacts and quality.
Restoration, reconstruction and calibration: modelling and estimation of noise, image smoothing and sharpening, statistical and adaptive filtering, reconstruction algorithms, calibration and restoration of intensities, geometric calibration.
Image registration and integration:
classification and applications of image registration methods, modelling geometrical transformations and deformations, matching of control points, similarity based registration , similarity measures and optimization methods, analysis and evaluation of registration methods, image integration examples.
Course is carried out on study programme
2nd Cycle Postgraduate Study Programme in Electrical Engineering
Objectives and competences
To introduce basic technologies for the acquisition of biomedical images and the procedures for their restoration, reconstruction, calibration and integration.
Learning and teaching methods
Basic theory, procedures and practical examples are considered at lectures, while practical knowledge is gained through problem-solving tasks at lab works.
Intended learning outcomes
After successful completion of the course, students should be able to:
- explain physical backgrounds of biomedical imaging techniques
- describe technological limitations and artefacts
- interpret information content of biomedical images
- process digital images with computer programs
- execute calibration and integration of multimodal images
- evaluate image quality
