The team at Prism have been developing, manufacturing, and supporting Radiotherapy Treatment Planning Systems (TPS) for more than 20 years. Initially we produced EMIPLAN, the first commercial system for CT based treatment planning. Subsequently we developed GE's highly successful RT/Plan, Target, Target Series2 and Target2 products.

The transition of GE's radiotherapy business to Varian Oncology Systems has not stopped this evolution. For Varian, as for GE, it is Prism in the background that continues to design, develop, manufacture, and support all of GE Medical Systems TPS products.

Now that neither GE nor Varian are actively promoting this product, Prism can no longer remain quietly behind the scenes, watching this heritage fade into oblivion. We believe this product is not ready for retirement, but has an important role to play in the treatment and care of cancer patients.

Prism now supports end users directly with a range of TPS workstation solutions, systems, upgrades, software maintenance, remote technical support, spares and parts repair programmes.

All of our solutions use high performance Sun SPARC systems with the secure and robust UNIX operating system to provide a reliable and stable computing platform for the clinically proven application software.

Our focus is on cost-effective practical solutions with an optimum balance of speed, accuracy and content, to deliver workhorse systems capable of continuously planning the majority of everyday radiation therapy treatments, curative and palliative.
