ELI2600 Medical signals and images Course description

The course describe the analysis and processing of signals in the frequency domain and analysis of systems for signal processing. Images are two-dimensional signals. The course also include the acquisition of image data, reconstruction of images and basic image processing of images for medical diagnostics.

MEK1000 Mathematics 1000, ELPE1300 Electric circuits, ELTS2100 Electronics and ELI2300 Dynamic systems.

No requirements over and above the admission requirements.

After finishing this course the student should have the following outcome:

Knowledge:

Understand the connection between the impulse response and frequency response

Understand that images are 2D signals and can be analysed accordingly

Understand the connection between resolution, impulse response, point spread function and frequency response.

Know how to describe wave propagation, reflection, refraction and attenuation of waves

Understand how an ultrasound image is formed and how the pulses are transmitted and recorded.

Understand how x-rays are generated and how an X-ray image is formed.

Understand how tomographic data are recorded and how CT-images are reconstructed.

Understand the physical principals of magnetic resonance and how images are formed.

Skills

Can describe and analyse signals with the use of the Fourier transform.

Be able to frequency analyse signals and design optimal processing

Can digitize signals by sampling and AD-conversion.

Can explain the difference between diagnostic and technical image quality.

Understand how images are reconstructed fro measured data.

Can use an ultrasound scanner and chose optimal settings.

General competence:

Be able to process a measured signal to optimize information content.

Be able to evaluate technical quality of an image in order to optimize diagnostic quality

The course includes the following topics:

• The Fourier transform and signal processing
• Ultrasound imaging
• X-ray imaging
• Magnetic resonance imaging
• Image reconstruction and tomographic reconstruction.

Lectures and exercises including use of MATLAB

Mandatory deliveries:

4 exercises

1 ultrasound lab

1 diagnostic group work

Each task should take about 5 hours of work

Individual written exam 3 hours.

The result of the exam can be appealed.

In the event of a resit or rescheduled exam, an oral examination may be used instead. In case an oral exam is used, the examination result cannot be appealed.

Approved calculator

Graded scale A-F

One internal sensor. External sensor is used regularly.

In case of a continuation exam, the exam can be oral with two internal sensors.
