About Modus QA

Founded in 2000, Modus Medical Devices Inc. develops and manufactures cost-effective and innovative quality assurance tools for advanced radiotherapy and medical imaging. Today, there are over 4,500 QUASAR™ phantoms being used in more than 2,700 leading treatment centres worldwide.

Advances in radiotherapy and medical imaging create the need for more sophisticated QA technology and solutions. Medical physicists are looking for ways to implement comprehensive test protocols and to reduce QA testing time, so they can get online faster and with more confidence.

Modus QA responds to this need by providing a wide range of QA phantoms and software for daily testing, commissioning new equipment and new techniques, and supporting the dosimetric and nondosimetric testing of upgrades, repairs and software fixes. Modus QA is proud to have been first to market in a number of significant areas, including: MRI-guided radiotherapy, daily on-board imaging, cone beam optical CT scanning for 3D dosimetry and nondosimetric QA. Modus QA also developed the first commercial programmable respiratory motion phantom and platform.

Modus QA has grown steadily based on a strong foundation of science, research, development and collaboration with medical physicists around the world. Today, Modus QA employees remain committed to assisting medical physicists in fulfilling their responsibilities more efficiently and accurately, which ultimately results in improved patient care.
