A better understanding of the vibration within MRIs would result in techniques to both improve the image resolution and lower the noise emissions. Direct improvement of health care for Australians will result. Both the patient and the working environment around these scanners will improve as well as image resolution. Presently imaging is possible at the cellular scale, but only through improved MRI stability will imaging reach the molecular level. Medical research that is linked to MRI imaging can be expected to advance in step with improved image resolution. The resulting knowledge could also be used in other research and industrial areas, including micro- and nano-scale devices, where vibration is a critical performance limiting factor.Read moreRead less

Inhomogeneous tissue conductivity influence on the forward and inverse electroencephalogram problems in realistic head models. The brain dysfunction indicators have been extremely difficult to obtain, largely because many disorders of higher brain function reflect abnormalities of brain function rather than apparent brain structure.

The brain dysfunction indicators have been extremely difficult to obtain, largely because many disorders of higher brain function reflect abnormalities of brain function rather than apparent brain structure. The neuronal generator localization and identification in this project will provide complementary information about source and timing of neural activities sub-serving higher brain function and form sequences of spatial-temporal brain activity image. That will enable the information from MRI, which has a good spatial but poor temporal resolution, and the information from EEG, which has a high temporal resolution on the scalp, to be combined to provide clinical psychologists and brain researchers a more efficient diagnostic tool.Read moreRead less
