A Single Digital Handheld Imaging Device For Use In Both Ophthalmology And Dentistry

Funding Amount
$431,221.00
Summary
Our aim is to produce and validate a single digital imaging device which can be used in ophthalmology (both for retinal and anterior segment imaging) and dentistry. This device will be low-cost, easy-to-operate and portable. Our planned development of the novel screening tool should help in bringing high quality, lower cost health care to those without easy access to it, firstly to residents of rural areas in Australia and then in developing countries in our region.

This device will be low-cost, easy-to-operate and portable. Our planned development of the novel screening tool should help in bringing high quality, lower cost health care to those without easy access to it, firstly to residents of rural areas in Australia and then in developing countries in our region. This can be achieved by more efficient screening methods and redirecting resources to target those with treatable eye disease only. The detection process can be progressively transferred to less expensive health workers while ophthalmologist input can be redirected to monitoring the screening results and performing surgery. The dentists travel infrequently to rural and remote WA. If the dentist can pre plan their treatment then it will be more efficient and possible to treat more people at each visit to remote and rural WA. With the help of the proposed imaging device for dentistry, the nurses and other allied personnel should be able to send the digital images in advance to dentist over Internet and therefore help dentist pre-plan their treatment. As a result, improved dental care for rural, remote and underserved communities will occur.Read moreRead less

We will be assessing and developing new portable ophthalmic imaging instruments, and validating them for common blinding eye conditions. The aim is to assess the ability of various health personal to document glaucoma, diabetic retinopathy, active trachoma, corneal scarring and cataract in rural screenings using digital imaging technology.

We will be assessing and developing new portable ophthalmic imaging instruments, and validating them for common blinding eye conditions. The aim is to assess the ability of various health personal to document glaucoma, diabetic retinopathy, active trachoma, corneal scarring and cataract in rural screenings using digital imaging technology. A network of ophthalmologists, health department personnel and aboriginal health workers in Western Australia will be involved. The project will also examine the quality of images obtained by health workers with various levels of skills and compare this with conventional photographs currently obtained by the screening network. Finally, the project will demonstrate practicality of the large scale storage of digital images of patient eyes. Preliminary evaluations have been performed on our teleophthalmology system using different portable instruments namely a handheld fundus camera, slit-lamp and indirect ophthalmoscope. We have also tested our teleophthalmology system at the Dr. Soetomo Hospital (Airlangga University) in Surabaya, Indonesia. Images captured using the handheld fundus camera were successfully transmitted to Lions Eye Institute through satellite, mobile and Internet lines. This pilot project has been sponsored by the Western Australian Department of Trade and Commerce and Telstra.Read moreRead less
Improved electrophysiological mapping techniques have enhanced understanding of arrhythmia mechanisms and the development of curative ablation strategies. Advanced mapping systems utilize online visualization of catheters, 3D geometry, and annotation of ablation sites. To date, all commercially available systems rely on proprietary equipment to locate catheter positions and reconstruct chamber shape from multiple site recordings. Thus, cost is prohibitive, limiting widespread availability.

Advanced mapping systems utilize online visualization of catheters, 3D geometry, and annotation of ablation sites. To date, all commercially available systems rely on proprietary equipment to locate catheter positions and reconstruct chamber shape from multiple site recordings. Thus, cost is prohibitive, limiting widespread availability. An alternative approach has emerged with the use of CT-MRI imaging and analysis. Novel techniques extract images of the endocardial surface from CT-MRI for use in electrophysiological mapping. This surface can be used as the chamber geometry instead of reconstruction based on expensive technology measuring spatial coordinates of the catheter tip inside heart. The proposed Anatomical Template Mapping System (ATMS) will generate maps of electrophysiological parameters derived from catheter recordings without the need for proprietary equipment. The physician will direct the virtual catheter position onto the 3D model of the chamber, obviating the need for equipment to map the spatial distribution of the catheters. The major advantage is that, without the need for specialized equipment, this method of mapping is substantially cheaper and can be used with any conventional electrophysiological mapping systems. Furthermore, it will provide the most important feature of the advanced mapping systems - an understanding of the arrhythmia mechanism.Read moreRead less
