ArcCHECK® — the only detector array specifically designed to detect errors during rotational intensity-modulated radiation therapy. It is the ideal solution for 4D pre-treatment patient QA for IMRT, VMAT, SBRT, and MRgRT, including reference linear accelerators Elekta Versa HD, Varian TrueBeam, Elekta Harmony, and specialized systems such as Varian Medical Systems® Halcyon™ and Ethos™ therapy, as well as Accuray® TomoTherapy and Radixact™ systems.

A powerful patient-centric ArcCHECK quality assessment device, recommended by AAPM Task Group 218 for 3D measurement requirements. It measures and correlates gantry angle, absolute dose, and time to identify any potential source of error within the patient volume.

Clinically Relevant Dose and DVH Quality Control

Identify TPS errors. With a single click, compare measured dose points with planned dose points. Review individual control points and user-defined full or sub-arc sections for a detailed overview of passing results, as well as low- and high-dose regions.

MLC Machine Quality Assurance

Additionally, use your ArcCHECK tests for machine QA by evaluating discrepancies between planned and delivered MLC positions and identifying leaves that may require maintenance.

The Gold Standard

ArcCHECK provides reliable plan delivery data and insights into potential errors. Its widespread adoption is driven by:

• Helical detector grid with 1,386 SunPoint® diode detectors to increase Beam's Eye View (BEV) data density
• Angular corrections with an accuracy of ±0.5° using the Virtual Inclinometer™
• Stable irradiation energy (BEV) for all gantry angles, measuring entrance and exit doses at different depths, and indicating potential delivery modeling and TPS errors for high- or low-dose levels
• Real-time electrometer that measures every pulse

Flexible Dose Measurements for More Rigorous Quality Control

Tissue-equivalent inserts support heterogeneity tests:

• Inserts include: brain, breast, bone, liver, lung, muscle, adipose, titanium, and water/air
• MultiPlug™ allows the use of ionization chambers, stereotactic detectors, and film for internal point measurements at any of 25 unique locations
• CavityPlug™ insert offers simplified isocentric dose measurement without the film and tissue-equivalent features of the MultiPlug insert
