Artificial intelligence (AI) has the potential to revolutionize the field of eye health monitoring. By leveraging AI, researchers can develop innovative techniques that provide sharper images and reduce the need for expensive examinations. Dr. Sylwia Kolenderska, a Senior Research Investigator in Physics at the University of Canterbury, is at the forefront of this groundbreaking work.
One of the key tools used in ophthalmology is optical coherence tomography (OCT). This light-based imaging technique allows ophthalmologists to capture three-dimensional internal images of the eyes, similar to an ultrasound but with light. However, the high cost of equipment has limited its accessibility to researchers and clinicians.
Dr. Kolenderska recognized the need for improvement in current OCT machines, particularly in data processing. While the image quality obtained from the existing expensive machines is satisfactory, the process of calculating the image from raw signals poses a significant bottleneck. Cheaper machines with inferior image quality are already available in the market, providing an opportunity for innovation in data processing.
To address this challenge, Dr. Kolenderska and her team have developed a solution that utilizes a neural network—an algorithm that learns patterns similar to a human brain. By replacing the standard algorithms used for OCT image calculation with this neural network, they can transform low-resolution data from inexpensive machines into high-resolution images comparable to those produced by expensive OCT machines.
Imagine a future where this technology is available as a hardware attachment, similar to a USB stick that can be plugged into any OCT machine. This would enable researchers and clinicians to enhance the image quality and obtain detailed insights into eye health without the necessity of investing in costly equipment.
The use of AI in OCT imaging not only improves image quality but also enhances the overall data interpretation process. AI algorithms excel in identifying relationships between different sets of data, making them robust interpreters. As a result, the enhanced image calculation process through AI is expected to deliver images up to six times better than the current ones.
The significance of Dr. Kolenderska’s work is reflected in her recent acceptance to attend the prestigious Computer Vision and Pattern Recognition 2024 conference. This recognition highlights the importance of her research in the field, as she joins only ten teams from Aotearoa New Zealand in the 41-year history of the conference.
To support the advancement of OCT imaging, Dr. Kolenderska was awarded a Smart Ideas grant of $999,999 in the 2023 Ministry of Business, Innovation and Employment Endeavour Fund investment round. This grant will provide the necessary resources to further refine the AI-based technology and accelerate its implementation in the field of ophthalmology.
Through her pioneering work, Dr. Kolenderska and her team strive to transform eye health monitoring by making it more accessible, cost-effective, and efficient. The integration of AI into OCT imaging holds tremendous promise for improving the accuracy of diagnoses and facilitating early intervention in eye-related conditions.
