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

THALES 3D MR SCANNER was developed by LAP in collaboration with MR-Linac users and is a manu-facturer-independent measurement tool for quality assurance. Different MR-compatible detectors can be used.

Precise

Selected hardware and software components ensure measurement system stability and accuracy, which significantly surpasses standard requirements.

Approved

THALES 3D MR SCANNER has successfully passed the European CE conformity assessment pro-cedure and is cleared in the USA under 510(k) K200907.

Customizable and automated

Not only can you create individual measuring plans but you can also choose from predefined ones.

All-in-one

Integration of all workflows, from setup to data verification and storage, simplifies the comprehensive clinical tasks.

Easy to use

The water phantom and the THALES software can be used easily and intuitively ensuring efficient and productive workflows.

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.

Levelling plate

Use the levelling plate to position the phantom optimally on the couch. Due to the weight of the phantom filled with water the couch might tilt imperceptibly. But even a small tilt can have an impact. Easily compensate any deviations with the help of integrated bubble tubes.
