Features

Simplicity

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 magnetic insert connection, the pResp was designed with the end user in mind, providing an intuitive motion-management QA tool.

Motion Control Options

Choose easy operation with local manual control at the motor or advanced programmable software driven control. The pRESP can produce simple translational motion or create complex 3D patterns with the QUASAR™ Respiratory Motion Rotation Stage (ITEM# 500-3330). With playback of motion waveforms, complexity is elevated to test the limits of your motion management systems.

Motion Precision

The QUASAR™ Respiratory Motion 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 zero to 60BPM are replicated with ease, testing a large range of clinical protocols.

Versatility

Supporting a comprehensive library of interchangeable inserts, the pRESP is a flexible tool able to test techniques on CT, LINAC, and PET platforms. Perform end-to-end validation using a variety of imaging and dosimetry inserts including ion chamber holders, film cassettes and OSLD holders.

Software

Included with the QUASAR™ Respiratory Motion Phantom is an intuitive programmable respiratory motion QA software. 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 QUASAR Respiratory Motion Phantom 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 3D waveforms, the pRESP 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.
