PHD Position: Optimising visual and diagnostic quality in radiography

The Norwegian Colour and Visual Computing Laboratory at Gjøvik University College invites applications for a PhD position available in the SHP project HyPerCept – Colour and Quality in Higher Dimensions.


Over the past decade, digital imaging has offered a new paradigm for radiology departments, resulting in an abundance of new imaging possibilities, as well as new ways of minimizing radiation dose necessary to obtain adequate diagnostic image quality. In order to properly exploit these possibilities, however, earlier research concluded that the complex relationship between radiation exposure, image noise, human observer, and diagnostic accuracy should be investigated further. One of the challenges in evaluating new imaging techniques has been that the measure applied for image quality must reflect the radiologist’s perception of quality.

The motive of this work is to develop new models, and re-use established models, for optimizing and predicting the diagnostic quality of images in terms of the sensitivity and specificity of diagnostic imaging protocols. The work will relate subjective evaluation criteria (e.g. receiver operating characteristics and visual grading analysis) to objective image quality metrics, including the optimization of images based on content analysis and the use of eye-tracking to understand how trained radiologists analyze diagnostic images.

The PhD work is a collaborative work between the Norwegian Colour and Visual Computing Laboratory at Gjøvik University College, the Faculty of Health Care and Nursing at Gjøvik University College, and the Intervention Centre at Oslo University Hospital. The workplace will be Gjøvik University College, but it is expected that the PhD student will visit and have stays at Oslo University Hospital.

Desired qualifications

Image processing, experience with subjective image quality experiments, radiology/radiography experience desirable. Programming experience is advantageous.

Duration and start date

This is a 3 year PhD position. Start date is between May and September 2014.

Eligibility criteria

As well as the specific eligibility criteria specified above, applicants are required to hold a good MSc (120 ECTS credits). Applicants are expected to have an outstanding academic record, be highly motivated and proactive, have excellent organisation and communication skills, and be eager to disseminate research results through publications and presentations at international conferences and seminars. Fluency in English is a prerequisite. Support will not be provided for doctoral fellowship candidates who have previously completed a doctoral/Ph.D degree.

General information

The annual salary is NOK 421.100 (approx. EUR 50.000) gross for a 100% position. Tax and medical insurance is deducted at approximately 30%. The public workforce strives to reflect the diversity within the population as far as possible.

Background: The Norwegian Colour and Visual Computing Laboratory

The Norwegian Colour and Visual Computing Laboratory ( is a research group within the Faculty of Computer Science and Media Technology at Gjøvik University College ( Since its foundation in 2001 the scope of interest has grown to cover colour science, colour imaging, image processing, and video processing in a broader sense, and our vision is to be one of the best research groups in this field. To achieve this vision the group employs a number of researchers with a broad competence basis in fields such as graphic arts, colour imaging science, media technology, computer science, signal processing, physics, image processing, and video processing. We also maintain an interactive open environment with strong national and international collaborators both in academia and industry. This has resulted in a wide range of fundamental and applied research projects which the group is actively involved in. Further, the group has a large number of well-equipped laboratories and conference facilities.
