Dynamic Cardiac Modeling for 3D Reconstruction from Ultrasound Imaging

Project Description

The goal of this project is to investigate the challenging problem of 3-D reconstruction of the heart from ultrasound (US) images, requiring deep understanding and advances in geometry, algebra and optimisation applied to computer vision.

Heart diseases are among the deadliest conditions in the western world. Early detection is a key toward efficient treatments. Cardiac imaging with US is of great help to practitioners for this, as it is cheaper than other imaging modalities for a first diagnosis. However, the heart being a deforming organ by nature, its 3-D reconstruction is subject to artefacts resulting from the non-sequential acquisition of the US images. While synchronizing the process to the heartbeat alleviates this effect, it makes the procedure slower. Instead, we propose to turn this very effect into helpful diagnostic cues as it captures information about how the heart is deforming. This information could be extracted to provide the clinician with both an accurate 3D reconstruction of the heart and with the dynamics of its deformation. Models of deforming organs’ surfaces already exist. However, they usually assume the surface to be inextensible and this needs to be relaxed to design a proper model of the heart.

Applicants wishing to apply should submit a one-page covering letter stating your background, academic qualifications, past research experience and interests, and future career aspirations. Please include a full CV, a copy of your academic transcript and the names and contact details of two referees to . Informal inquiries or queries can be sent to the same email address.

Funding Notes

To be eligible for a fully-funded PhD studentship, covering tuition fees and an annual stipend set at UKRI rates, the candidate must have no restrictions on how long they can stay in the UK and have been ordinarily resident in the UK for at least 3 years prior to the start of the studentship (with some further constraint regarding residence for education, further guidance can be found on the EPSRC website). Due to funding requirements the University of Dundee is limited to accepting only UK students.
