SH2310 Radiation Detectors and Medical Imaging Systems 7.5 credits

Strålningsdetektorer och medicinska bildgivande system

This course is intended for students in the program Engineering Physics, the Master program Medical Engineering or other programs.

The goal with the course is to provide an understanding of the field of medical imaging, with focus on x-ray based modalities. The medical imaging machines are important diagnostic tools for doctors working in the clinic and a good image can save a life. However, exposing patients to ionizing radiation comes with an associated risk from the radiation dose. Therefore, it is of utter most importance that the information acquired from an x-ray measurement is utilized to its fullest and this is where the research and development of medical imaging modalities has its focus – optimization of image quality versus patient dose.

Medical imaging is a multi-billion dollar industry and the machines are produced by many of the big electronics companies in the world, including Phillips, Siemens, General Electric, Toshiba, etc.

Course information

Content and learning outcomes

Course contents *

The course treats the physical, mathematical and technological aspects of medical imaging systems from a signals-and-systems point of view. Modalities (imaging types) covered include:

  • Projection Radiography

  • Computed tomography (CT)

  • Planar Scintigraphy

  • Single photon emission computed tomography (SPECT)

  • Positron emission tomography (PET)

  • Ultrasound imaging (briefly)

  • Magnetic resonance imaging (MRI) (briefly)

Numerical methods to quantify the performance of medical imaging systems are presented. The design of medical imaging systems usually involves a number of tradeoffs involving parameters such as: contrast, spatial resolution, noise, image acquisition time, size and cost. It is a major goal of the course to provide an understanding of these relations.

Intended learning outcomes *

After completion of the course, the student should be able to:

  • Explain the physical and technological principles behind various types of radiation detectors and imaging modalities.

  • Use the signals and systems approach to describe and estimate the quality of an imaging system.

  • Display understanding of the Fourier space representation of images.

  • Use the physics of radiation absorption and generation together with the geometries of the different imaging modalities to solve numerical problems.

  • Perform image reconstruction for Computed Tomography in simple cases and understand the sinogram representation of images.

The student is required to use a mathematical programming language such as MATLAB for the hand-ins and laboratory work.

To qualify for the highest grades, the student should also demonstrate the ability to:

  • Identify physical and current technological limitations of medical imaging systems.

  • Apply knowledge from imaging modalities within the course content on novel imaging techniques.

  • Solve medical imaging problems that relate to statistics and probability theory.

  • Show understanding of the connection between the image quality metrics (e.g. PSF, MTF, NPS, SNR) and the final image.
