The use of PET-MRI in radiotherapy treatment planning

PET/CT is frequently used to assist in the planning of radiotherapy treatments. The PET information can help with determining the extent and function of the tumour as well as possible involvement of lymph nodes. This could result in improved targeting of the radiation to the disease.PET/MRI offers a number of advantages over PET/CT for head and neck cancer radiotherapy treatment planning. The MRI offers superior soft tissue contrast and no ionising radiation dose compared to the current standard of care, …

Develop point-of-care microfluidic technologies for cardiovascular and cerebrovascular diseases

Excessive clotting (thrombosis) leads to the cardiovascular diseases such as heart attack and stroke, killing one Australian every 12 minutes. It has long been recognized that platelets play a central role in thrombosis and are unique in their ability to form stable adhesive interactions under conditions of rapid blood flow.We've recently discovered a new ‘biomechanical’ prothrombotic mechanism that highlights the remarkable platelet sensitivity to the shear stress gradients of blood flow disturbance. Importantly, we've found that current anti-thrombotic drugs, such …

Advanced artificial intelligence based ultrasound imaging applications

Our research in the space of advanced quantitative medical imaging is investigating how to use ultrasound as a real time volumetric mapping tool of human tissues, to guide in a reliable and accurate way complex medical procedures1. We have developed several novel methods which make use of the most cutting-edge artificial intelligence technology2. For example, to show where the treatment target and the organs at risk are at all times during treatments in radiation therapy3, 4; or to inform robots …

Portable magnetic resonance imaging of biological tissues

Magnetic Resonance Imaging (MRI) provides a unique way of non-invasive investigation of the 3D organisation of biological tissues and materials.The physical basis of MRI is the intrinsic magnetism of atomic nuclei. The magnetic moment of a single atomic nucleus is extremely small and effectively undetectable. However, the collective magnetisation of nuclei in a macroscopic sample can be sufficiently large to be detected, especially in the case of nuclei that are abundant in the sample. This is the case in most …

Use of depth sensing technology in radiotherapy and medical imaging

Consumer-grade depth sensing technology has in recent years become widely available. A number of vendors have developed similar technologies.Some examples of these technologies include:Intel’s RealSense™Asus Xtion depth sensorQualcomm Spectra ISP platform, now in its second generation.The systems make use of camera technology that measures the distance to a surface. Rapid image acquisition can then enable real time motion detection of location of the surface. The infra-red transmitter and sensor use a time-of-flight method to construct a depth map, in millimetres, …
