Modus Medical Devices Inc., commissioned OES Inc. to design, develop, and manufacture, an intelligent single axis motion control device and related software for their "Quasar™  Programmable Respiratory Motion Phantom". 

The Quasar™ Programmable Respiratory Motion Phantom is a state-of-the-art breathing simulator for conducting quality assurance testing on radiotherapy systems. Using a laptop to communicate with The Quasar™ Programmable Respiratory Motion Phantom, technicians select from standardized test objects, which in turn allows the Programmable Respiratory Motion Phantom to simulate a patient's breathing function. 

Quasar™ Programmable Respiratory Motion is a flexible QA tool designed to perform both dosimetric and non-dosimetric tests on radiotherapy systems. The phantoms are used for regularly scheduled testing, as well as commissioning new systems and upgrades, and testing repairs.

Modus investigated many off-the-shelf solutions before commissioning OES to develop a solution for their specific requirements. OES's intelligent single axis stepper motor controller offers many advantages, including an Ethernet connection, the elimination of numerous individual devices, and far greater stepper motor control and product functionality.
