20 Years of MUCheck Software

In the past 20 years, ODS has grown from a small mom-and-pop startup to a tried-and-true fixture in the industry. In 2018, our software can handle all your second-check needs, from the simplest calculation to a complex arc plan. We also support calculations for brachytherapy, TomoTherapy, CyberKnife, Gamma Knife, and more. Read about our company’s journey from a small 2-person operation to being trusted in clinics all over the world.

MUCheck: The Beginning

The story of MUCheck begins with a marriage.

Greg was a software engineer. His wife Margaret was a medical dosimetrist. In the 1990s, Greg noticed that Margaret was spending a great deal of time second-checking her monitor unit calculations manually. Hoping to ease her workload, Greg decided to write a software program to speed the process up. It worked like a charm, and MUCheck was born.

By 1998, many people in the radiation therapy field wanted to use MUCheck and the demand was increasing. Greg and Margaret obtained an FDA clearance to market MUCheck and the company Oncology Data Systems, Inc. was born.

Growth and Change: 20 Years of Innovation

Over the past 20 years, the cancer treatment industry has seen some tremendous change. As cancer treatments became more sophisticated and complex, MUCheck was refined and updated to adapt to technology changes in the medical physics field. More features were added. Additional employees were hired. MUCheck software continued to grow.

What started as a simple program for calculating basic conformal beams eventually grew to include electron calculations, SRS treatments, DICOM import capability forward plans, and more. However, it didn’t stop there. MUCheck now offers a second-check solution for brachytherapy, CyberKnife, TomoTherapy, and Gamma Knife treatment modalities.

Today, Oncology Data Systems is proud to offer a full suite of MUCheck products that can be configured to your specific treatment needs.


This is where it all began. MUCheck is our flagship product offering quick, reliable calculations for conformal photon and electron beams.
