QUASAR™ Motion MR Platform

A first of its kind tool, designed to bring motion MR QA to your advanced imaging systems.


Understanding the impact of motion is pivotal in optimizing advanced radiation therapy outcomes. Meet the new QUASAR™ Motion MR Platform, a first-of-its-kind tool, designed to bring motion MR QA to your advanced imaging systems. Being fully MR-safe, the platform is capable of providing motion QA within your MR-driven workflows. Capable of inducing up to 4cm motion at 60 BPM to any stationary phantoms weighing up to 45kg/100lbs*, the platform is setting a new standard in motion management. Remarkably versatile across all imaging platforms, it empowers you to conduct a thorough end-to-end verification of your motion management workflows.

The intuitive programmable respiratory motion QA software is included with QUASAR™ Motion MR Platform. This locally installed package enables the control of the phantom’s motion and customization of supplied and imported motion waveforms. An incorporated Deep Inspiration Breath Hold Function increases workflow efficiency for users to test DIBH protocols



Featuring a large platform surface of 48.5 cm x 31 cm and accommodating up to 45 kg (100 lbs), the QUASAR™ Motion MR Platform is designed to seamlessly incorporate motion into a wide range of industry-leading large-scale phantoms. This includes compatibility with prominent models such as the Scandidos Delta 4 MR+ and other dosimetry arrays.

MR Performance

The QUASAR™ Motion MR Platform boasts industry-leading motion performance without compromising MR image quality. With an advanced piezoelectric drive system and RF shielded components, it is meticulously designed to preserve image fidelity.


The QUASAR™ Motion MR Platform is 100% MR Safe, enabling seamless utilization across various imaging platforms such as MR, CT, CBCT, PT, and PET. Its integrated AP/PA surrogate platform facilitates testing for SGRT and respiratory trigger components. With analogue signal input and output capabilities, the MR Platform is well-suited for testing beam latency parameters and other advanced harmonized functions.

Motion Precision

The phantom exhibits detailed sensitivity when replicating captured or created waveforms. A highly responsive motor repositions the translation stage every 10 ms (100x per second) providing real-life breathing replication. Waveforms from 0-60BPM are easily replicated with sub-millimetre accuracy, allowing for the testing of a large range of clinical protocols. (Performance dependent on mass and waveform combination).
