Learning Outcomes

Upon successful completion of this subject, students should:
  • be able to explain the basic relationship between the image form and the perceptual and physiological characteristics of the human observer.
  • be able to analyse and explain the impact of both physical and human factors on the important concepts of digital image quality.
  • be able to evaluate the architecture and components of a digital computer and the logical nature and function of software.
  • be able to compare and contrast the basic principles underpinning the various forms of digital image processing techniques available in diagnostic imaging and be able to manipulate images to improve image quality.
  • be able to explain the processes of image acquisition, enhancement, display, storage, transmission, and retrieval systems.
  • be able to evaluate various tomographic image reconstruction and visualisation algorithms in diagnostic imaging.
  • be able to explain the concepts of imaging informatics including computer assisted diagnosis.
  • be able to apply a range of practical skills in image processing techniques found in diagnostic imaging systems.


This subject will cover the following topics:
  • The human observer: characteristics, limitations, basic psychophysics of human vision; colours in human vision and colour models; diagnostic imaging perception.
  • Image quality: physical factors and measurements of image quality; signal to noise ratio (SNR); image display device and human influence on image quality; image quality assessment methodologies.
  • Digital image fundamentals: computer hardware and software; digital image fundamentals; medical image formats; digital imaging systems.
  • Digital image processing: contrast stretch; edge enhancement; noise reduction; smoothing; various spatial domain transforms and image enhancement techniques in frequency space.
  • Image Analysis: simple feature detection; histograms; statistical analysis; region of interest; parametric imaging.
  • Digital Tomographic image reconstruction and visualisation: Fourier transformation image reconstruction; filtered back projection image reconstruction; iterative image reconstruction; tomographic image visualisation; co-registration / fusion techniques.
  • Digital image storage and communications: image storage media; image compression techniques; picture archiving and communication systems (PACS); digital image communication in medicine (DICOM).
  • Imaging informatics: hospital and radiological information systems (HIS and RIS); diagnostic imaging workflow and integrated health empire (IHE); computer assisted diagnosis (CAD).
