Medical Imaging

Aim

The course should provide a possibility for the student to acquire knowledge in biomedical imaging technologies and diagnostics and their impact on biological tissue. After passing the course the student should be able to:

• explain effects of ionizing radiation on biological tissue and the human body .
• describe methods to measure ionizing radiation, to do dosimetry calculations and their relation to safety regulations.
• describe how medical images are generated using x-ray radiation.
• describe how different components and processes in the image generation chain influence the final image.
• describe and explain reconstruction principles for computed tomography images.
• describe principles for nuclear magnetic resonance imaging.
• describe the development of contrast in MR images.
• apply knowledge about MRI contrast to select the most appropriate pulse sequences to a chosen application.
• describe the principles of MRI-image reconstruction.
• summarise and explain the basic physical principles exploited for generating ultrasound images in medicine.
• describe and model how ultrasound systems can achieve spatial localisation.
• explain the reconstruction process of ultrasound images.
• optimise and choose methods to improve ultrasound image quality.
• summarise the impact of ultrasound on biological tissue.

Content

• Image generation technology using X-ray, CT, MRI and ultrasound.
• Imaging diagnostics and enhancement.
• Radiation biology and safety.
• Laboratory work: Image quality in medical imaging.
• Workshop with hand-in assignments where various aspects of CT, MRI and ultrasound imaging are simulated.
