It’s about time.

Greater efficiency in quality assurance has been a long time coming.

In the last 30 years, countless new radiation therapy modalities and treatment techniques have been embraced. Independent QA tools have kept pace, but have arrived as separate packages – designed for specific tasks, with unique software, databases and workflows to learn.

With demands for increased patient throughput, improved quality of care and reduced operational costs, every minute counts. And, with patient safety on the line, shortcuts are not an option.

Globally, nearly 119 million treatment fractions were treated in 2012. By 2035, that number is expected to jump to at least 204 million per year.

Apply the Platform

SunCHECK is designed from the ground up to support the real world of radiation therapy – where every combination of OIS, TPS, linac and clinical implementation is unique.

SunCHECK’s purpose is Patient Safety.

With SunCHECK, you have a fully independent, integrated workflow.

  • One Solution for Radiation Therapy QA
    Manage all Patient and Machine QA in the same place to save time and reduce the likelihood of errors going undetected.
  • Speed and Efficiency through Automation
    Cut time consumed by manual tasks, and build in more bandwidth for data analysis, clinical decisions and continuous improvement.
  • Access from Anywhere
    Untether your team with secure, browser-based visibility to the insights they need to see, wherever they are.
  • Seamless Clinical Integration
    Make your QA work harder, regardless of technologies in place. Count on custom installation, with a quick start-up guaranteed.

“Having patient information, having machine information all in one easily accessible place… that’s basically what you would want in a system.”

Robert Staton, Ph.D., UF Health Cancer Center at Orlando Health, Orlando, FL


Get an overall view of Patient and Machine QA, with quick access to results, reviews, to-do’s and approvals. Verify QA has been completed successfully, and on-time.

Prioritize Your Patients

Trade time spent moving, saving and searching for files for greater focus on improving treatment quality.

With SunCHECK Patient, all phases of Patient QA integrate into a flexible, automated and seamless workflow.

  • Secondary Checks
    Perform 3D secondary dose calculation for the systems your clinic uses.
  • Phantomless Pre-Treatment QA
    Complete your 2D/3D pre-treatment QA, with both EPID measurement and log file-based options.
  • In-Vivo Monitoring
    Verify and track dose throughout your patients’ courses of treatment.

“Because this system is fully automated so that no physicist time is required for data acquisition and evaluation, daily patient treatment QA is feasible.”

Zhuang AH, Olch AJ., J Appl Clin Med Phys (2018)


Verify setup, first fraction, and intra-fraction motion (when in EPID mode) against the treatment plan. Patient position and anatomy are factored into the analysis to enable true dosimetric In-Vivo Monitoring.


Pre-set, yet customizable dose tolerances for each phase of Patient QA allow you to obtain meaningful QA results quickly and easily. See the impact to different criteria sets instantly.

Get More from Your Machines

Improve standardization and ease compliance reporting for Daily, Monthly and Annual QA

With SunCHECK Machine, you drive efficiency and critical consistency across locations, machines and staff. In turn, you are able to satisfy requirements of TG-142, TG-51 and your internal requirements.

  • Daily, Monthly, Annual QA
    Ensure consistency among machines and clinics with shared tolerances. Apply ready-to-use, but customizable templates for efficient QA. No more spreadsheets!
  • Measurement Device Connectivity
    Automate beam measurement with direct device integration to Sun Nuclear’s Daily QA™ 3 and IC PROFILER™. Eliminate the need for additional software and transfer of data.
  • Imaging, MLC and VMAT QA
    Simply deliver test beams. With acquired image or log file data, SunCHECK Machine automatically processes the data and analyzes results.

Monthly constancy and beam quality checks take only 15 minutes for 5 beams with SunCHECK Machine vs. 60 minutes without.

Sun Nuclear internal testing


TG-142 pre-set templates by modality support Daily, Monthly and Annual QA. Easily customize templates and tolerances to fit your needs.


Auto-populate your Daily, Monthly and Annual QA results with direct connectivity to Daily QA 3 and IC PROFILER devices, eliminating the need for additional software and potential data entry errors.

Partnership from the Start

Implementing SunCHECK, as with any Sun Nuclear solution, is more than a
one-time interaction.

In-Depth Training

Our headquarters includes a 5,000-square-foot Training Center that replicates the clinical environment of a Radiation Therapy center, including a fully functional Varian TrueBeam®. Courses on a variety of subjects are offered year-round and are delivered by Sun Nuclear subject matter experts and experienced clinical users.

World-Class Support

Live support is available Monday-Friday, from 8 a.m. to 8 p.m U.S. Eastern Time. Virtual support is available 24/7 through our support website, with access to helpful documents like FAQs and user guides. Enter support tickets at your convenience—staff are available to support after hours commissioning and testing.

Engaging, Ongoing Education

In support of continuing education, Sun Nuclear hosts live webinars and talks at relevant meetings and symposia throughout the year. Practical topics are presented by clinical users and product experts. And live events include demonstrations of hardware and software solutions.


When we introduced PerFRACTIONTM and SNC MachineTM, we started the journey towards the fully integrated QA platform that is now SunCHECK.

With the introduction of SunCHECK 2.0, the platform is complete – able to address all your needs for Patient and Machine QA in a convenient and consistent software solution. But more than that, SunCHECK 2.0 will change the way you perform QA. It may even change the way you speak…

Definition of SunCHECK
