NaviGAIT: New Software To Simplify Interpretation Of Gait Analysis Data

Funding Amount
$179,905.00
Summary
NaviGAIT is a new software package to support interpretation of gait analysis data. It is based upon Gait Profiling, a new technique to reduce the complexity of such data. At present data intepretation is restricted to a few expert clinicians. The new software will allow non-expert clinicians to interpret data and hence make gait analysis more accessible, cheaper and more clincally useful. A module of NaviGAIT specifically for children with cerebral palsy will be the first to be developed.
Dynamic In Vivo Size & Shape Measurement Of The Human Upper Airway Using Endoscopic Long-range Optical Coherence Tomogra

Summary
This project will fund the construction of a clinically deployable prototype device to measure changes in upper airway size and shape in patients with obstructive sleep apnoea. We have recently developed and validated a technique based on endoscopic optical coherence tomography (OCT). Preliminary in vivo studies have been performed in the human upper airway and the results published. To our knowledge, this is the only such system world-wide capable of making these important measurements.

We have recently developed and validated a technique based on endoscopic optical coherence tomography (OCT). Preliminary in vivo studies have been performed in the human upper airway and the results published. To our knowledge, this is the only such system world-wide capable of making these important measurements. The technique has wide commercially applicability as it can be used to measure the internal dimensions of any hollow organ system.Read moreRead less
Development Of Quantitative Tools For Assessment Of Regional Cardiac Function By Echocardiography

Summary
The application of ultrasound imaging to the assessment of cardiac function (echocardiography) is an invaluable tool for the assessment of patients with known or suspected cardiac problems. The assessment of contraction in each region of the heart is probably the most important of the reasons for doing this test, as regional function is disturbed in patients with coronary artery disease, which is one of the most common causes of death in Australia. The problem is that this analysis is currently ....The application of ultrasound imaging to the assessment of cardiac function (echocardiography) is an invaluable tool for the assessment of patients with known or suspected cardiac problems. The assessment of contraction in each region of the heart is probably the most important of the reasons for doing this test, as regional function is disturbed in patients with coronary artery disease, which is one of the most common causes of death in Australia. The problem is that this analysis is currently completely subjective, and the reliability of the tool is based upon the availability of an experienced observer. This is particularly a problem in rural Australia, as most specialists with expertise in this modality work in the capital cities, and especially a problem in Queensland, where fewer than half of the population live in the capital. The cardiac imaging group at the University of Queensland have been working in collaboration with GE-Vingmed Ultrasound to develop a quantitative technique for the assessment of regional cardiac function since 1997. This collaboration has been the source of a number of published papers and presentations at international meetings. Our group is considered to be a world leader in the field and our industry partner is clearly the most focused of its competitors in addressing this problem. This submission seeks to address several remaining problems. The data thus far addressed function during stress, when the condition of most patients is similar. Tissue velocities are more variable at rest, and a more sophisticated approach is required to accurately measure the lower velocities in the resting state. This research plan seeks support for the development of a new, high frame-rate acquisition that would facilitate the examination of velocities relative to each other, so that translational motion of the heart does not influence the reading. This new method would then be validated against other techniques for assessing function and disease.Read moreRead less
A Motion Correction Technique For Accurate PET/CT Brain Imaging In Paediatric And Dementia Patients

Funding Amount
$190,450.00
Summary
PET-CT imaging is a vital tool in the diagnosis and management of patients with brain disorders including dementia, epilepsy and cancer. However images are often distorted by patient motion, particularly in demented and paediatric patients. The CI has recently developed a motion tracking and correction method to derive images nearly free of motion effects. This aim of this project is to evaluate its impact on image quality in a variety of patients referred for PET- CT brain investigations.
