SH2314 Medical Imaging Signals and Systems 7.5 credits

This course webpage contains general information about the course. For detailed information about this year's course round see the course page in Canvas.

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 trade-offs 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 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.

Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale

A, B, C, D, E, FX, F

Examination

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

One written exam (TEN1; 4,5 university credits) and laboratory/project work (LAB1; 3 university credits). Hand-in assignments during the course give bonus points for the written exam.

Other requirements for final grade

Passing grade (A-E) in the written exam and passing grade (P) in the lab part.

Opportunity to complete the requirements via supplementary examination

Opportunity to raise an approved grade via renewed examination

Ethical approach

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
