Research students exhibition catalogue 2011
The catalogue demonstrates the scope and vibrancy
of current inquiries and pays tribute to the creative
capacity and investment of UCA research students.
It brings together contributions from students who
are at different stages in their research ad/venture.
Their explorations are connected by the centrality of
contemporary material practices as focal point
for the reconsideration of societal values, cultural
symbols and rituals and their meaning, and the
trans/formation of individual, collective and national
identities The media and formats employed range
from cloth, jewellery and ceramics to analogue film,
the human voice and the representation of dress and
fashionin virtual environments. Thematic interests
span from explorations at the interface of art and
medical science to an investigation of the role of art
in contested spaces, or the role of metonymy in âhow
the arts thinkâ And whilst the projects are motivated
by personal curiosity and passion, their outcomes
transcend the boundaries of individual practice and
offer new insights, under-standing and applications
for the benefit of wider society. Prof. Kerstin Me

A Smartphone-Based Tool for Rapid, Portable, and Automated Wide-Field Retinal Imaging.
Purpose:High-quality, wide-field retinal imaging is a valuable method for screening preventable, vision-threatening diseases of the retina. Smartphone-based retinal cameras hold promise for increasing access to retinal imaging, but variable image quality and restricted field of view can limit their utility. We developed and clinically tested a smartphone-based system that addresses these challenges with automation-assisted imaging. Methods:The system was designed to improve smartphone retinal imaging by combining automated fixation guidance, photomontage, and multicolored illumination with optimized optics, user-tested ergonomics, and touch-screen interface. System performance was evaluated from images of ophthalmic patients taken by nonophthalmic personnel. Two masked ophthalmologists evaluated images for abnormalities and disease severity. Results:The system automatically generated 100° retinal photomontages from five overlapping images in under 1 minute at full resolution (52.3 pixels per retinal degree) fully on-phone, revealing numerous retinal abnormalities. Feasibility of the system for diabetic retinopathy (DR) screening using the retinal photomontages was performed in 71 diabetics by masked graders. DR grade matched perfectly with dilated clinical examination in 55.1% of eyes and within 1 severity level for 85.2% of eyes. For referral-warranted DR, average sensitivity was 93.3% and specificity 56.8%. Conclusions:Automation-assisted imaging produced high-quality, wide-field retinal images that demonstrate the potential of smartphone-based retinal cameras to be used for retinal disease screening. Translational Relevance:Enhancement of smartphone-based retinal imaging through automation and software intelligence holds great promise for increasing the accessibility of retinal screening
