Vision RT Unveils Three New SGRT Innovations at ASTRO 2025: OIS Reports, Auto ROI, and Beam Guide

At ASTRO 2025 in San Francisco, the spotlight on surface guided radiation therapy (SGRT) was brighter than ever, and Vision RT was at the center of the conversation. This year, Vision RT had the opportunity to showcase three groundbreaking new modules for AlignRT – OIS Reports^TM, Auto ROI^TM, and Beam Guide^TM.

Each has been designed to simplify clinical workflows, improve consistency, and ultimately deliver better care for every patient, every fraction.

OIS Reports: Seamless Data Integration

A major theme at ASTRO was automation in radiotherapy, and the new OIS Reports module is a perfect example. Traditionally, AlignRT has been able to generate detailed treatment reports, but transferring this information into an Oncology Information System (OIS) required manual effort. With the new OIS Reports module, that process is fully automated.

OIS reports converts AlignRT session data into DICOM format and exports it directly into the OIS, automatically mapped onto the correct time point within systems such as ARIA**. Screenshots and end-of-treatment reports are securely stored alongside other clinical records, creating a single, centralized patient timeline.

This innovation not only streamlines clinical workflows but also supports audit, billing, and compliance. With potential upcoming reimbursement opportunities tied to SGRT, having complete, automatically archived data will be a critical advantage.

As Adi Robinson from AdventHealth Florida shared,

 “The OIS reports module automated our SGRT reporting process. Now we never miss an SGRT report, and the physician can review and approve them together with the IGRT daily review.”

Auto ROI*: Consistency Without Compromise

Another ASTRO presentation highlight was Auto ROI, which automates the creation of regions of interest for AlignRT tracking. Appropriate ROIs are critical for precise positioning, but drawing them manually can be time-consuming and inconsistent  between users.

Auto ROI leverages DICOM body contours from the treatment planning system to generate tailored ROIs for each protocol. Clinicians can accept, edit, or choose from alternative suggestions, resulting in faster preparation, consistent accuracy, and reproducible results across patients and users.

This innovation particularly resonated with clinics managing high-volume cases where both speed and precision are critical.

As Luke Rock, Chief Medical Physicist at Beacon Hospital, explained:

“Auto ROI was quick and easy to use and will definitely save us time in clinic, as well as improve consistency between regions of interest.”

Beam Guide*: Predicting Beam Delivery Before It Happens

Perhaps the most talked-about feature at ASTRO was Beam Guide, which takes SGRT beyond detection, into prediction.

While Cherenkov imaging allows therapists to detect unintended dose delivery in real time, Beam Guide overlays projected radiation fields directly onto the patient during setup. By visualizing potential misalignments in advance, clinicians gain an extra layer of safety, ensuring radiation is delivered where intended.

During his presentation at our ASTRO booth, Mike Tallhamer, Chief of Radiation Physics at AdventHealth, shared his experiences with this innovation:

“With Beam Guide, we can now confidently verify that what we planned is exactly what happened.”

Every Patient, Every Fraction

AlignRT, the market-leading SGRT solution, takes innovation further with three new powerful tools: OIS Reports, Auto ROI, and Beam Guide. These build on clinically focused features like Postural Video, giving Vision RT customers a single platform that delivers safety, speed, and consistency.

These innovations highlight Vision RT’s ongoing commitment to pushing the boundaries of SGRT and making radiation therapy more effective for cancer patients.
