Advanced methods for intraocular imaging

The ability to image the retina of the human eye at high resolution is fundamental to improving understanding of ocular physiology, ocular optics and disease diagnosis. This project applies the relatively new application of active optics to vision science, and will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability. Three-dimensional holography of human eyes is expected to give notbefore experienced resolution images of the retina and better understanding of the optical characteristics of the refractive surfaces and media in the eye.

Retina disease is often an indicator of a sick body, so high precision instruments for the diagnosis of retinal health allow for early intervention. The instrumentation developed for this project employs adaptive optics and active optics, with new beam shaping and holographic recording techniques to gain high-resolution images of the retina.

The PhD candidate, will focus primarily on post-processing techniques for retinal and holographic imagery, an area in which it is vital that images reflect the true underlying physiology and for which a clear distinction from post-process and systemic artifacts is needed. To devise methods and algorithms that can separate systemic and algorithmic artifacts from the true imaging information is not an easy task, given the high spatial frequency and typically low contrast of these images, even with the refinements employed in data capture. The diagnostic community are rightly skeptical of the validity of final imagery, and vision science must develop a framework that guarantees the images, based on the imaging modalities employed to gain the data.

This scholarship is provided under the Australian Research Council Discovery Projects funding; DP140101480, “Advanced methods for intraocular imaging. The student will be under primary supervision of Dr Andrew Lambert at UNSW Canberra in the School of Engineering and IT with cosupervision by Prof David Atchison from the QUT Institute of Health and Biomedical Innovation. The student will expect to undertake full-time study at UNSW Canberra, with occasional visits to QUT in Brisbane to participate in data collection.

The candidate will be expected to have a strong engineering and image processing background, and an interest in optics and vision science. The applicant will be expected to have the equivalent of a first-class honours degree from UNSW. The successful applicant, subject to satisfying the admission requirements, will be awarded an ARC funded Scholarship with an annual tax-free stipend of $26,592. This scholarship is for a period of 3 years, subject to satisfactory progress reviews. Applications will be accepted until a suitable candidate is found.

The Canberra campus of the University of New South Wales is located at the Australian Defence Force Academy (ADFA). ADFA is located in an Australian bushland setting less than five kilometres from the city centre and the Canberra airport.

The UNSW Canberra campus has a large and comprehensive library, state-of-the-art computing facilities, well-equipped and modern laboratories. 2 Canberra is a modern city chosen as Australia's national capital in 1908. Its name comes from the local Aboriginal word "Kamberra" meaning "meeting place". As Australia's capital city, Canberra is the focal point for activities and events that affect and influence the nation. It is the home of Federal Government and the public service, a focus for business and industry, home to the international diplomatic community, a place of study or just a great place to live.
