Purposefully Automated
SunCHECK Patient streamlines data transfer and time-consuming tasks, enabling greater focus on improved treatment quality.

Common Analysis Tools & Centralized Storage of Results
In support of standardization, SunCHECK Patient provides common analyses across each Patient QA phase -- and stores all results for easy retrieval and review.

Custom-Fit for Your Clinic
We optimize SunCHECK Patient for the planning and delivery technologies you use -- and provide flexible, automated analysis options for every step. As updates occur and your needs evolve, SunCHECK Patient adapts.

Phase 1: Plan Quality Checks

Assuring plan quality requires significant experience, focus and expertise. PlanCHECK eases this time-intensive task.

PlanCHECK automatically loads patients’ plan files into the Treatment Planning System and performs the plan checks – reducing the time required for this demanding process.

Phase 2: Secondary Dose Calculations

Secondary dose calcs remain a key safeguard before treatment begins. DoseCHECK provides calculated-versus-planned 3D Clinical Goals analysis, as well as per-beam and composite MU comparisons.

A collapsed cone convolution/superposition algorithm supports C-arm linacs and the Varian Halcyon™ System. A Monte Carlo dose calculation supports Accuray TomoTherapy®/Radixact® Systems, HDR Brachytherapy and treatments using stereotactic cones.

Phase 3: Pre-Treatment QA

For pre-treatment QA, SunCHECK Patient flexibly supports 3D CRT, IMRT/VMAT AND SRS/SBRT calculation and delivery.

  • Choose phantomless, using the EPID and/or Log File data
  • Directly connect with ArcCHECK® for an array-based approach

Results are presented via a dashboard and patient list — no need to manually create, register, or input patients. Email notices are sent for failed results.

Phase 4: In-Vivo Monitoring

With SunCHECK Patient, you can automatically verify:

  • Patient setup against the treatment plan,
  • First fraction dose delivery vs. plan, and
  • Ongoing fractions for anatomy- and setup-related issues.

Results are analyzed in 3D using EPID and/or Log File data, or in 2D through the Transit Dosimetry feature, with no additional time or effort required.

“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)

The SunCHECK dashboard provides an overview 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.

A consistent, interactive event display shows point dose, 2D analysis, 3D analysis, structure-based gammas, overall gamma, DVHs, and images and dose displays.

At-a-glance patient list shows workflow phases and pass/fail status, with ability to review details and status of individual patient treatments, and drill down into per-beam results. Names shown are fictitious and randomly generated.

Pre-set, yet customizable, dose tolerances for each phase of Patient QA provide meaningful results -- with 70+ common protocols preloaded. You can instantly analyze the impact of different criteria sets -- including dose deviations -- and quickly switch criteria as needed.

User-defined absolute limits for specific clinical dosimetric goals allow scoring of results relative to specific dose/volume constraints established by RTOG, QUANTEC, Emami, or your own protocols.

Answering Clinical Need for Efficiency, Insights

More than 1,600 clinical users have adopted SunCHECK, and a wealth of publications affirm its clinical value. Review our publications to learn more.

Browser-Based Access

In-depth insights for each phase of Patient QA are within easy reach for your staff, from any networked computer.

TG-218 Compliant

Like ArcCHECK®, SunCHECK Patient supports AAPM Task Group 218 requirements for pre-treatment QA.

Absolute Dosimetric QA

Using calibrated EPID data, true dosimetric In-Vivo Monitoring is clinically feasible, creating a fully independent absolute dosimetric QA of patient treatments.

ArcCHECK Integration

ArcCHECK connectivity within SunCHECK Patient expands pre-treatment QA options, with enhanced root-cause analysis of delivery issues.

Complete Device Control

SunCHECK allows full control of essential Sun Nuclear Patient and Machine QA devices, without having to launch or maintain a separate application.
