The Centre for Image Analysis (CBA) is a joint research entity between
Uppsala University and the Swedish University of Agricultural Sciences.
CBA was established to through research and development reinforce the
knowledge needed for an operative and sensible use of digital image
analysis in society. More information can be found at http://www.cb.uu.se.
Three-dimensional volume images are used frequently in medical
applications today. With higher precision in the image acquisition
equipment, storing and processing these images require an increasing
amount of data processing capacity. Traditionally, three-dimensional
images are represented by cubic (or cuboid) picture elements on a cubic
The two-dimensional hexagonal lattice has some advantages over the
traditionally used square lattice. For example, fewer samples are needed
to get the same reconstruction quality and it is less rotational
dependent. A corresponding three-dimensional lattice is the
body-centered cubic (bcc) lattice. In theory, almost 30% fewer samples
can be used to get the same reconstruction quality when the bcc lattice
is used compared to the cubic lattice.
Most three-dimensional image acquisition methods are based on
tomography, i.e., the three-dimensional image is constructed by a stack
of two-dimensional images, each acquired separately. To take full
advantage of the high sampling efficiency of the bcc lattice, the image
should be acquired as a full three-dimensional image. In this project,
methods for image acquisition, analysis, and visualization will be
developed for three dimensional medical images represented on the bcc
With the methods developed in this project, it will be possible to
process three-dimensional images with 30% less data without affecting
the image quality. Our intention is that this project will lead to
faster processing of images with less demands on the data storage capacity.
Cooperation partner in this project is the Division of Radiology,
Department of Oncology, Radiology and Clinical Immunology, Uppsala
A MSc or MEng or similar degree in science/technology with a focus on
computer science and mathematics is a suitable background. Experiences
from digital image processing is highly valued.
Uppsala University is striving to achieve a more even gender balance and
women are especially encouraged to apply.
PhD positions are primarily intended for the students’ own graduate
education. In addition to research education, teaching or other duties
at CBA to an extent of about 20% of full time is included in the
position. Formal acceptance as a PhD student is a prerequisite for the
The application should contain a CV, high school and college
transcripts, letters of recommendations, and a letter describing why you
want to become a doctoral candidate and why this line of research
appeals to you.
