QUASARTM Motion MR Platform
The new QUASAR™ Motion MR Platform is the first fully MR-safe solution to bring genuine motion quality assurance to advanced imaging and radiotherapy workflows. It can drive any stationary phantom (up to 45 kg / 99 lb) through repeatable motions of up to 4 cm at 60 BPM, giving clinicians a realistic, end-to-end way to verify and refine their motion management strategies across all imaging platforms. By uniting high-fidelity motion simulation with seamless MR integration, the platform sets a new benchmark for precision treatment QA and empowers teams to optimise outcomes in advanced radiation therapy.*

Features
Powerful
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.
Versatility
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-millimeter accuracy, allowing for the testing of a large range of clinical protocols. (Performance dependent on mass and waveform combination)
Software
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
Complex Motion Control Options
The MR Platform offers full control of your phantom’s motion profile. Our Respiratory Motion QA Software offers multiple operation modes to increase utility. From adjustable sinusoidal waveforms and simple test patterns to accurate playback of complex waveforms, the platform offers the flexibility to choose your motion complexity for your required testing sequence.
Customizable Waveforms
In addition to an extensive library of pre-loaded waveforms, the Respiratory Motion QA Software enables the import of acquired waveforms from a number of respiratory gating and motion tracking systems. The waveforms are completely customizable, improving the user experience when modifying waveform patterns to achieve the desired testing protocol.
