Course Aim

The course objective is that the students can explain how a digital image is produced and stored, and be able to describe simple imaging operations. The goal is that the student should have good knowledge of digital imaging. This means that the student should be able to:

  • describe how a digital image is stored in the computer memory
  • explain the concept of pixel value
  • interpret the histogram of an image
  • describe how the resolution of an image affects the ability to see details
  • describe how the color depth of an image affects the ability to see details
  • describe how filters are used to reduce noise in the image
  • describe the difference between various file formats used for storage of images
  • give examples of how three-dimensional images can be displayed on a two-dimensional computer screen
  • know how distortion can be corrected digitally
  • mention how images are archived in hospital settings
  • know different concepts and their synonyms in digital imaging.

 The course also aims to develop the ability of the students to interact with collegues and to carry out supervised tasks. This means that the student should be able to:

  • formulate subject-related questions and answers orally and in writing
  • present new knowledge orally and in writing
  • provide feedback on the work of others


The focus lies on basic introduction to digital imaging, relevant to the radiology nursing profession. The following topics are included:

  • general Introduction, what is a picture, how can you portray something you do not see?
  • how a digital image is constructed (spatial resolution)
  • how the image is stored in the computer (quantization)
  • how to represent a digital image (histogram)
  • what is contrast (thresholding)
  • dynamic, fast and slow processes
  • interference and noise
  • edge Information, the definition of edges and sharp edges
  • introduction to color images
  • introduction to image formats
  • image processing - compression
  • 3D images
  • distortion
  • DICOM and PACS


The course is offered as a distance course and the literature should be read independently. Lessons will be given through web-based tools. Laboratory work is carried out from the home computer remotely and guidance is provided by web-based tools. Campus days occur during the course, where either seminars or study visits occur. The course concludes with a joint oral and written presentation and opposition to a project where digital imaging within a given modality should be covered by either a literature study or by a description of their own practical work.


Examination consists of completed and reported laboratory, visited workshops and a final presentation with the opposition of a project (in groups or individually) (project 4.5 points, laboratory 3 points). These parts are mandatory. The connection to the hospital environment and the ability to formulate concepts are evaluated in the project report. Other goals are examined in written answers to the laboratory questions. Alternative forms of examination may occur.
