Medical Image Analysis

Jason Dowling
Team Leader
Medical Image Analysis

Our team partners with clinicians to develop and validate novel technology to, extract quantitative information from medical image data and to understand and improve disease diagnosis, treatment planning and treatment delivery.

In collaboration with clinical partners our team produce high impact scientific research in a range of disciplines. The team currently receive additional funding support from six NHMRC project grants, an NHMRC development grant, and two Advance Queensland Post-Doctoral Research Fellowships.

Impact on the Health System
Our projects develop cutting edge validated methods to acquire and automatically extract information from medical images to improve diagnosis, treatment delivery efficiency, cost-effectiveness and patient quality of life.

Our Solutions
Our solutions have been developed in partnership with healthcare practitioners at many sites across Australia.
