We’re not a catalog company. We’re a focused team of engineers, physicists, sales leaders, and supply chain experts who understand the clinical pressure of maintaining reproducible patient positioning, accuracy across fractions, and smooth therapist workflow.
Every product we represent solves a specific positioning challenge. We’re selective by design. Each product we offer earns its place by solving a real clinical problem.
We don’t just offer support, we offer partnership.
Every solution we offer prioritizes patient comfort and treatment accuracy.
Designed by people who understand the daily challenges you face.
We're here when you need us, not just when it's convenient for us.
Whether you're running traditional double-shell setups or mask-free SGRT workflows, IOS helps you deliver accurate, comfortable, and consistent treatment, day after day.
