Stringent requirements from new MR LINAC technology

The age of MRI-based radiation therapy is upon us. This also means new challenges in terms of quality assurance, as existing water phantoms for commissioning and annual inspection of MR LINACs are not suited to this environment. On the one hand, repeatable and precise control in the magnetic field is virtually impossible with conventional water phantoms; on the other, the accelerator design imposes geometric limits.

The demands placed on a motorized water phantom for MR LINACs are therefore high:

no ferromagnetic components
radiation-resistant components
lightweight and compact design

THALES 3D MR SCANNER – water phantom for commissioning and QA

Features

Independent

Manufacturer independence gives you maximum flexibility. All MR-compatible detectors can be used.

Automated

Automated setup and predefined measurement sequences save valuable processing time during commissioning and annual QA.

All-in-one

Integration of all workflows, from setup to data verification and storage, simplifies the required test routines.

Precise

Selected hardware and software components ensure scanning system stability and accuracy, which significantly surpasses clinical requirements.

Intuitive

The web-based software guides you through the entire process and stores the results centrally on the server.

MR-conditional

The entire system, and all components are certified for use under MR conditions.

THALES software

The THALES software offers much more than mere control of the water phantom used for MR LINAC commissioning and quality assurance. You require no additional tools for the acquisition of data, its administration, or its evaluation. The data archive has an intelligent search, so that you can find all measurement sequences in no time and output individual reports. Role-based user management secures access to data and settings. Any current browser can be used as the user interface. Data administration takes place centrally, via a current MS Windows Server version. A standalone solution can also be installed.

Development in progress

THALES 3D MR SCANNER is developed for and with ViewRay MRIdian users. Prototypes are being tested worldwide by renowned institutions.

"We have been positively impressed by the quality of the 3D MR compatible Water Phantom system prototype that has been left to us for evaluation with the ViewRay MRIdian LINAC. We are looking forward the release of the Water Phantom system from LAP on the market".
