Project outline:

Applications are invited for a PhD funding opportunity based within the Translational
Imaging Group of the Centre for Medical Image Computing at UCL, commencing in
September 2014.

UCL was recently awarded £10million to develop better tools and imaging
techniques that will improve the success of surgery and other therapies on
unborn babies in collaboration with KU Leuven, Great Ormond Street Hospital and
University College London Hospital. Key to this widely scoped endeavour is the interaction
between the information provided by real-time imaging, notably fetoscopy, and
the robotic actuators to be developed for fetal surgery. Although visual
servoing is a standard tool in traditional robotics, its application to robotic
fetal surgery poses a number of challenges due in part to the large deformations
happening in the surgical scene but also due to the small field of view of the


This PhD project will focus on the extraction of localisation information
from the fetoscopic view. A first objective will be to register, in real-time,
the consecutive images of the video stream so as to dynamically expand the
field of view through the construction of a mosaic image. Visual servoing will
then be built on top of the real-time registration. Applications include
compensation of physician tremor and application of motion constraint to
protect the uterine wall and fetal membrane. Close collaboration with the
Mechanical Engineering department at KU
Leuven, Belgium is to be expected. Candidates with a strong interest in the
following areas are encouraged to apply: medical image registration, visual
servoing, computer vision, translational applications of medical image
computing, and real-time image processing. Informal enquiries are welcomed.
