Varian Medical Systems and ScandiDos have signed a non-exclusive distributor agreement, which covers the ScandiDos Delta4PT pre-treatment verification system, for use with Varian's RapidArc radiotherapy technology, the TrueBeam system, and technology for IMRT.

The agreement allows Varian and its affiliates world-wide to offer Delta4PT to their customers, providing additional solutions for fast and accurate verification of complex radiation therapy technologies.

ScandiDos Delta4PT QA system is a quality assurance tool used to test radiotherapy treatment plans to help insure that they will result in the desired dose distribution before actual treatments commence.

The system allows the users to quickly verify and approve the delivery of complex radiotherapy treatment plans by simulating treatments and generating real dose measurements in relation to a three-dimensional target volume.

Delta4PT has been used in the validation of new treatment techniques such as Varian’s RapidArc and has been in clinical use for IMRT and arc therapy QA.
