Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index ....Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index in turbid media, including biological tissue in vivo. We propose to apply our novel technique to study tissue calcification, a serious problem in cardiology, by making use of the refractive index contrast mechanism. Calcification of smooth muscle cells and aorta subdermal implant models will be studied aiming for prevention of calcification-associated pathologies.Read moreRead less
Noval design of a Bi-Ventricular Assist Device (BVAD) Centrifugal Heart Pump as an Implantable Total Artificial Heart. In Australia, 40%(50,797) of all deaths each year are related to heart disease and accounted for 12% (A$4Billion) of total recurrent health expenditure. This innovative research aims at developing a single biventricular assist device (BVAD) driven by a magnetically suspended double-sided centrifugal pump impeller. Current techniques require two implantable devices, thus preventi ....Noval design of a Bi-Ventricular Assist Device (BVAD) Centrifugal Heart Pump as an Implantable Total Artificial Heart. In Australia, 40%(50,797) of all deaths each year are related to heart disease and accounted for 12% (A$4Billion) of total recurrent health expenditure. This innovative research aims at developing a single biventricular assist device (BVAD) driven by a magnetically suspended double-sided centrifugal pump impeller. Current techniques require two implantable devices, thus preventing smaller patients from access to BVAD technology. The expected outcomes will be a significantly small and compact device and provide an alternative to open-heart transplantation, thus helping to alleviate the demand on donor hearts, as well as the strain on the Australian Heath Care System caused by cardiovascular disease.Read moreRead less
Development and evaluation of a remote monitoring system and its application to cardiac rehabilitation and occupational health. This project further develops and evaluates a system developed by the Industry Partner which permits real-time remote monitoring of a person's cardiac activity, position and velocity via GPS, and selected aspects of motion and posture using accelerometry. The study has three aims: to enhance the system's capacity for remote monitoring of human motion and physiology; to ....Development and evaluation of a remote monitoring system and its application to cardiac rehabilitation and occupational health. This project further develops and evaluates a system developed by the Industry Partner which permits real-time remote monitoring of a person's cardiac activity, position and velocity via GPS, and selected aspects of motion and posture using accelerometry. The study has three aims: to enhance the system's capacity for remote monitoring of human motion and physiology; to test its ability to support cardiac rehabilitation for those unable to access hospital-based programs; and to evaluate its application to the monitoring of workloads in physically demanding tasks associated with cardiovascular ill-health and musculoskeletal injury.Read moreRead less
Development of a multivariate physiologic state space analysis framework for characterising functional properties of the cardiovascular system. Pathologies of the cardiovascular system arising from heart diseases make a major contribution to morbidity and mortality in the Australian community. This project will provide new diagnostic modalities based on advanced noninvasive bioinstrumentation, signal processing and model-based analytical methods to identify early signs of developing disease or t ....Development of a multivariate physiologic state space analysis framework for characterising functional properties of the cardiovascular system. Pathologies of the cardiovascular system arising from heart diseases make a major contribution to morbidity and mortality in the Australian community. This project will provide new diagnostic modalities based on advanced noninvasive bioinstrumentation, signal processing and model-based analytical methods to identify early signs of developing disease or the acute exacerbation of existing disease. The impact of these new technologies on the early diagnosis and improved triaging of patients in emergency departments is potentially profound and could result in improved healthcare outcomes for the patients and reduced admissions to hospital as well as the development of a substantial international market.Read moreRead less
Hybrid Sensor-based Physiological Control of an Implantable Rotary Blood Pump. With over 11 million people needing heart transplants worldwide and only 3000 donor hearts, an effective alternative therapy is needed. The Ventracor Ltd. rotary blood pump is one possible approach whereby a fully implantable mechanical device assists the failing heart. The innovative steps in this research proposal will be a means to robustly and safely control the speed of the pump to meet the metabolic needs of the ....Hybrid Sensor-based Physiological Control of an Implantable Rotary Blood Pump.

The Ventracor Ltd. rotary blood pump is one possible approach whereby a fully implantable mechanical device assists the failing heart. The innovative steps in this research proposal will be a means to robustly and safely control the speed of the pump to meet the metabolic needs of the body. Apart from the obvious health benefits for patients, this will provide the company with a huge market advantage that will also help to bolster the Australian medical device industry.Read moreRead less
