Pinnacle : About


Pinnacle, owned by Koninklijke Philips N.V (Philips), is one of the three most commonly used treatment planning systems in radiation oncology clinics. At one time they were widely considered the best, most accurate and efficient TPS, however, in recent years use of the Pinnacle has declined considerably.



Geometrics Corp. was founded in 1992 by Mark Gehring, Cameron Sanders, Paul Reckwerdt and “The Rock” Mackie to commercialize the Stereotactic Radiosurgery Planning System that had been developed at UW-Madison. The software quickly evolved to become the Pinnacle3 Treatment Planning System, and in 1996 Geometrics Corp. was acquired by ADAC Laboratories for $3.9 million. Philips then acquired ADAC Laboratories for $426 million in 2000.


Current Direction

The newest version of Pinnacle3, P16, was released in 2017. The software features an entirely new GUI with capabilities common to Windows-based programs. Deformable registration was introduced within the Dynamic Planning Module. In the distant future, Philips intends to eventually offer a cloud-based, fully hosted planning solution.

On 12/20/2021 Pinnacle and Elekta jointly announced ePinnacle. The new system will offer integrated Record and Verify software which will allow the direct exchange of information between treatment planning and delivery systems.
