Layman's description

This new collaboration between the Department of Computer Science, HYMS
(York) and the Craniofacial Unit at Great Ormond Street Hospital (London) aims
to provide surgical planning aids and surgical outcome assessment for patients
suffering from chronic facial abnormalities, in particular congenital conditions, such as Apert syndrome. This project is the first step in building an accurate, state-of-the-art deformable 3D face model that is able to show how the face should look were abnormalities removed.

Key findings

FINDINGS/RESULTS

This was effectively a pump-priming project to allow York (Computer Science and HYMS) to start collaborating with clinicians in Great Ormond Street Hospital (GOSH). It was a 3-man month project in terms of RA time.

(i) We built a software tool that allows the fast manual mark up of 3D face scans - features of this software development include multiple simultaneous views of the surface to allow accurate placement of manual landmarks and auto-piloting between different regions of the face that require landmarking. (ii) A training set of 3D faces was marked up using the "me-in-3D" dataset at GOSH. (iii) We tested our auto-landmarking software developed in a recent PhD at York (Clement Creusot's work, also the RA) an the results were successful on adults, but less successful on children - we think because the training set consisted exclusively of adults.

The findings were encouraging and, as a follow on to this, we have gathered a team of collaborators to work on an EPSRC proposal to continue this work. We will develop our spare model fitting process into a dense model fitting process.

Nick Pears (PI) was awarded a Royal Academy of Engineering / Leverhulme Trust Senior Research Fellowship to continue developing this work over the 2013-14 academic year (12 month fellowship).


COLLABORATIONS

Main collaboration is with Great Ormond Street Hospital, in particular David Dunaway, clinical lead of the Craniofacial Unit, and Allan Ponniah, registrar, who coordinated the me-in-3D dataset collection. Also, there have been several new collaborations off the back of this project, including with 3DMD (Chris Lane CEO) the manufacturers of medical industry standard 3D scanning equipment, Cincinnati Childrens Hospital Medical Center (Donna Jones) and Alder Hey Children's Hospital (Christian Duncan).

APPLICATIONS SUBMITTED

Applied for a Royal Academy of Engineering / Leverhulme Trust Senior Research Fellowship to do follow on work. The application was successful leading to an additional 12-month period of research.

In Feb 2014, applied to EPSRC for a 4 year follow on project (6 RA man-years). The FEC is costed at 823K. Partners include three children's hospitals: Great Ormond Street, Alder Hey and Cincinnati, and 3dMD, the market leader in medical 3D surface scanning. Reviewer scores were 6/6, 6/6, 5/6 and the proposal was taken forward to panel. At panel it was ranked 9th of 18 proposals and the first 8 were funded.

In May 2015 we extended our team of academics and we applied for a Wellcome Trust Collbaorative Science Award, but we were not successful in that bid.
