Visage Imaging Releases Amira 5.3

Introducing a new powerful toolset for Neuroscience and a multitude of new features and improvements

SAN DIEGO, California, July 19, 2010 - Visage Imaging(R), Inc., a wholly owned subsidiary of Pro Medicus Ltd.
(ASX: PME), is pleased to announce the immediate release of Amira 5.3, a new
major version of its market-leading software platform for visualizing,
analyzing, and presenting complex 3D and 4D biomedical data.

Amira's entirely new Neuro option contains a comprehensive set of tools
for neuroscience research, specifically MR diffusion tensor imaging (DTI) as
well as CT and MR brain perfusion imaging. The new option provides efficient
calculation of perfusion results as well as analysis and display of
multi-channel functional image data including gradients, tensors, and fiber
tracking.

"With the new version of Amira, I finally get all the brain imaging tools
I need, integrated in a single platform. The results from different
modalities and functional calculations can be combined, processed, and
presented together in very flexible ways - far superior to any other solution
I know," says Prof. Dr. A. Brawanski, head of neurosurgery at the Regensburg
University Hospital in Germany.

Furthermore, Amira 5.3 comes with a large number of new tools and
improvements, such as DemoDirector, an easy-to-use graphical front end for
creating animations and presentations using the popular DemoMaker module; a
largely redesigned set of tools for spreadsheets and statistics; a number of
enhancements to the popular FilamentEditor; and a full integration of the
widely used Insight Segmentation and Registration Toolkit (ITK) into Amira's
Developer Option.

"Amira 5.3 is the most powerful and reliable Amira ever - with hundreds
of improvements and dozens of new modules and enhancements, designed in
collaboration with leading research institutions all around the world. I am
always impressed to see the level of activity and innovation in the
ever-growing Amira community. Their contribution is what makes Amira so
strong and so unique," says Dr. Hartmut Schirmacher, Director of Product
Management for Visage Imaging.

Amira 5.3 is available for Windows 32 and 64 bit, Mac OS X, and Linux
platforms. For more information, visit the product website
