With technology at the core of delivering care in radiation oncology, it is imperative that patient safety is not compromised. IHE-RO is an initiative that helps to ensure a safe, efficient radiation oncology practice by improving system to system connections.

Submit Your Clinical Challenge for IHE-RO to Solve

Integrating the Healthcare Enterprise-Radiation Oncology (IHE-RO) is an ASTRO-sponsored initiative for improving the functionality of the radiation oncology clinic. Created in 2004, it is composed of members of the radiation oncology team, administrators and industry representatives that work together to ensure a safe and efficient radiation oncology clinic. The IHE-RO task force develops IHE Integration Profiles, which specify how industry standards are to be used to address specific clinical problems and ambiguities. These integration profiles are then tested at ASTRO’s annual Connectathon, where vendors meet to test the connectivity of their products.

An important part of helping to ensure patient safety, IHE-RO is part of ASTRO’s Target Safely initiative.

What is IHE?

IHE, Integrating the Healthcare Enterprise, is an initiative of health care professionals and industry representatives working together to improve the sharing of information between computer systems in health care. Radiation oncology is one domain of many under the greater umbrella of IHE. More information about IHE.

How can I join IHE-RO?

IHE-RO is composed of organizations that seek to solve interoperability issues in radiation oncology. Membership in IHE-RO is through IHE.

How can I be a part of IHE-RO?

To learn how to join IHE-RO, please choose the “About IHE-RO” tab.

The field of radiation oncology requires precise and accurate technology and vendors are at the forefront of making sure the technology provided is optimal for cancer patients. IHE-RO offers vendors the ability to work directly with clinicians to advance safe and appropriate care for patients.


Learn how to join IHE-RO by choosing the “About IHE-RO” tab.


The Connectathon is an event where vendors have the opportunity to come together to determine their software connectivity with each other and test their products against the different challenges posed in a typical radiation oncology practice.

  • Mimics real life scenarios in which issues of interoperability come up on a daily basis.
  • Ensure seamless transfer of information from one computer to another.
  • ASTRO has sponsored the Connectathon at its headquarters since 2004.

Once a vendor has passed these tests, their product is “IHE-RO Compliant”. The vendors release Integration Statements to show how the product is IHE compatible.
