Quasar - Heavy Duty Respiratory Motion Platform

The QUASAR™ Heavy Duty Respiratory Motion Platform features a vertical chest-wall platform that is compatible with a number of Surface Guided Radiation Therapy Systems (SGRT), such as: Vision RT, C-RAD, Brainlab, and Varian Identify. Easily import patient-specific waveforms from various motion capture and waveform generating sources. Compatible with the following file formats: VXP, .CSV, .TXT, .DCM, .LOG, .DAF, .IMA

Modus QA has developed an easy-to-use phantom with comprehensive testing capabilities for demanding motion protocols in modern radiation therapy departments. From its manual operation mode to its rapid 30° offset alignment wedge, the QUASAR™ Platform HD is an intuitive motion-management QA tool designed with the end-user in mind.

Easily adjust motion waveform amplitude and frequency with either local manual control at the motor or advanced programmable control at the software interface. Apply a user-defined rotated arrangement to your existing phantoms to create complex motion profiles. With playback of motion waveforms, complexity is elevated to test the limits of your motion management systems.

The QUASAR™ Platform HD 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.

The QUASAR™ Platform HD is compatible with any stationary phantom up to 45kg (100lbs). Specialized feet support allows for the rapid indexing of the phantom in either a linear or 30° rotated offset arrangement for multidirectional motion capabilities. With acceleration and velocity parameters set correctly (according to the weight of the phantom), imported waveforms can be analyzed and modified so that they playback safely.
