Development of new methods to measure in vivo properties of human body tissues. This project will develop new methods of noninvasively measuring the viscoelastic properties of soft tissues in live humans, using a novel magnetic resonance elastography technique. These methods will be applied to study the operation of the human muscle-tendon system, differences in neck muscle properties with age and gender and to measure the properties of the human brain, kidney and liver in vivo. These techniques ....Development of new methods to measure in vivo properties of human body tissues. This project will develop new methods of noninvasively measuring the viscoelastic properties of soft tissues in live humans, using a novel magnetic resonance elastography technique. These methods will be applied to study the operation of the human muscle-tendon system, differences in neck muscle properties with age and gender and to measure the properties of the human brain, kidney and liver in vivo. These techniques may be useful in diagnosing soft tissue disease or injury which are currently difficult to detect using standard imaging techniques. It will also explain how the muscle-tendon unit moves during normal motion in live humans.Read moreRead less

Haemodynamic investigation of flow diverter stents for the treatment of intracranial aneurysms. This project will explore the engineering of a flow diverter, an endovascular device for the treatment of brain aneurysms. The project will determine the optimal design of new types of flow diverters, which in turn could improve the effectiveness of treatments, thus reducing the associated costs of cerebral haemorrhage and stroke.
Fundamental theoretical and experimental investigation of cartilage mechanics. Arthritis and chronic joint symptoms are one of the leading causes of disability in the community, yet a fundamental understanding of joint mechanics has yet to be realised. The aim of this project is to develop a new state-of-the-art mathematical model describing cartilage behaviour in humans.

Arthritis and chronic joint symptoms are one of the leading causes of disability in the community, yet a fundamental understanding of joint mechanics has yet to be realised. The aim of this project is to develop a new state-of-the-art mathematical model describing cartilage behaviour in humans. The model will explain how activities like walking maintain healthy cartilage by transferring growth factors through the tissue, and quantitatively explain how wear is minimised in cartilage through weeping lubrication. This model will progress our understanding of cartilage mechanics in health and disease, and so help Australians age well and productively.Read moreRead less

This study will provide new knowledge on osteoarthritis progression by allowing strategic use of national health resources. A fuzzy expert system, to be developed utilising the diagnostic/prognostic techniques of this study will significantly reduce cost and time. The project will contribute to the National Strategy by helping older Australians; the major group of osteoarthritis sufferers, to retain their health, independence and productivity.Read moreRead less

High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in heal ....High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in healthcare, through clinical gait analysis and gait rehabilitation (diagnosis, prevention and treatment of movement disorders); in sports, through the development of personalized training programs for elite athletes; and in entertainment, through the creation of physics-based animations for the video/digital games industry.Read moreRead less

Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton ....Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton) do not move dental implants. This project aims to develop new multiscale modelling and remodelling techniques in computational mechanics to explore the roles played by connective soft tissue in bone adaptation. Expected project outcomes would increase our understanding in biomechanics and affect health care disciplines such as orthodontics, prosthodontics and orthopaedics.Read moreRead less

Summary
A Multi-Axis Biomaterials Testing Facility. Damage to bones and joints, due to injury or diseases such as osteoporosis and arthritis, is a major cause of disability and cost to the nation. Australia's ageing population contributes not only to an increasing incidence of such conditions, but also to more patients out-living implants such as replacement joints. In 2001-2, Australia spent over $800 million on joint replacement. Because over 11% of procedures are revisions of failed implants, even sm ....A Multi-Axis Biomaterials Testing Facility. Damage to bones and joints, due to injury or diseases such as osteoporosis and arthritis, is a major cause of disability and cost to the nation. Australia's ageing population contributes not only to an increasing incidence of such conditions, but also to more patients out-living implants such as replacement joints. In 2001-2, Australia spent over $800 million on joint replacement. Because over 11% of procedures are revisions of failed implants, even small improvements in implant life represent significant cost savings. By accurately simulating conditions within the body, this biomechanical testing facility will lead to new developments in implant designs and materials, in turn improving quality of life, productivity and treatment costs.Read moreRead less
