Descriptif :
This module introduces the main medical imaging acquisition modalities used in clinical practice. It presents the fundamental physical principles underlying image formation, as well as the key parameters influencing image quality and appearance. The course also highlights typical clinical applications associated with each modality.
Within the context of the BME DaTSHealth Master, the objective is to provide students with a solid understanding of the nature, structure, and limitations of medical image data prior to their analysis, interpretation, and processing using advanced computational techniques.
Learning outcomes :
After completing this course, students will be able to:
- Understand the physical principles behind major medical imaging modalities
- Identify the key components of imaging systems and acquisition processes
- Explain how acquisition parameters affect image quality, resolution, and contrast
- Recognize the characteristics and limitations of different types of medical imaging data
- Relate imaging modalities to their main clinical applications
- Interpret imaging data in light of its acquisition conditions
Course content (overview):
