QUASAR™ MRgRT Insight Phantom

Overview

The QUASAR™ MRgRT Insight Phantom is an all-in-one phantom designed for treatment planning and delivery quality assurance for cutting-edge MR-SIM and MR-LINAC systems.   

This large Field of View phantom fulfils geometric distortion, image quality and targeting testing recommendations prescribed by AAPM TG284 and the Elekta Consortium on Machine QA for the Elekta Unity. The MRgRT Insight eliminates the need for several ad-hoc, task-specific devices in place of a single, comprehensive, multi-purpose phantom.

The versatile design facilitates quick Daily QA procedures and automated image quality results.   Built-in features and optional accessories expand the functionality of the phantom to perform thorough testing including: 

Uniformity, spatial resolution, slice thickness, geometric distortion, phased-array SNR, large FOV B0 assessment, laser and patient table positioning accuracy, imaging/laser isocenter agreement, MV/MR coincidence QA and end-to-end dosimetry. Automated image quality analysis software empowers the MRgRT Insight to provide a view into your system and monitor the performance of key functional components. 

Software

The QUASAR™ MRgRT Insight software application is designed to improve workflow efficiency for MR medical physicists and to provide a view into the overall performance of their MR systems. Software features such as an intuitive pass/warn/fail mode, automated image analysis and performance metric calculations allow users to efficiently evaluate system performance and create trending data to help monitor any deviations. Manual analysis tools add the ability to further investigate results and independently calculate metrics.
