The Daily QA™ 4 Pro from Sun Nuclear (Mirion Technologies) represents the next generation of daily quality assurance devices for linear accelerators (LINACs). For the first time, a single indexed, imageable device combines dosimetry, Winston-Lutz measurement, and imaging verification (kV, MV, and CBCT) — eliminating the need for multiple phantoms and setups for morning QA. Interphysix is the exclusive Sun Nuclear distributor in Portugal.
What is the Daily QA™ 4 Pro?
The Daily QA 4 Pro is the most advanced daily QA device on the market, designed to simplify and accelerate the mandatory morning checks before starting radiation therapy treatments. It integrates the highest number of detectors of any device in its category, including SunPoint® diodes and vented ion chambers, and is fully compatible with the SunCHECK platform for centralized QA data management.
The device comes with SunCHECK Local included, enabling a future gradual migration to the full SunCHECK platform without additional immediate investment.
Key advantages over the Daily QA 3
The Daily QA™ 3 has been the industry standard for daily QA. The new Daily QA 4 Pro significantly elevates the available capabilities:
- Integrated Winston-Lutz — assess geometric accuracy of beam isocenter without switching devices
- Imaging verification — kV, MV, and CBCT in the same setup, unique on the market
- More detectors — field coverage from 2×2 cm to 20×20 cm
- Fewer room entries — a single positioning for all checks
- SunCHECK Local included — migration path to centralized platform
- Wireless BaseStation — wireless communication for maximum convenience
- User-replaceable battery — uninterrupted operation
Complete dosimetry in a single device
The Daily QA 4 Pro provides comprehensive dosimetry metrics in a single quick setup:
- Output dose
- Field size
- Beam flatness and symmetry
- Beam shape and penumbra
- Dose per pulse
- Checks for fields from 2×2 cm to 20×20 cm
These metrics are essential to ensure the linear accelerator is operating within safety parameters before starting daily treatments, in compliance with AAPM TG-142 recommendations.
Integrated Winston-Lutz — no device switching
One of the most significant innovations of the Daily QA 4 Pro is the integrated active Winston-Lutz measurement. Traditionally, Winston-Lutz verification requires a dedicated phantom, careful positioning, and a separate setup from dosimetric QA. With the DQA4 Pro, this geometric verification is performed on the same device and within the same workflow, allowing you to assess beam isocenter accuracy without interruptions.
This capability is particularly critical for SRS (Stereotactic Radiosurgery) and SBRT treatments, where submillimeter geometric accuracy is essential.
kV, MV, and CBCT imaging verification
The Daily QA 4 Pro is the only daily QA device on the market with integrated imaging verification capabilities. In a single morning QA session, you can verify:
- kV (kilovoltage) — kV portal imaging system
- MV (megavoltage) — MV portal imaging
- CBCT (Cone-Beam CT) — cone-beam computed tomography
This eliminates the need for separate imaging verification setups, significantly reducing total daily QA time and ensuring complete verification of all LINAC systems.
SunCHECK integration
The Daily QA 4 Pro integrates natively with the SunCHECK platform, Sun Nuclear’s centralized machine QA management solution. Guided setup within SunCHECK walks users through the entire process — from account configuration and device calibration to daily QA template creation.
With SunCHECK, daily QA data is automatically collected and stored, eliminating manual entry errors. Automatic alerts for late or failed results put your machine QA on autopilot.
TG-142 compliance for daily QA
The Daily QA 4 Pro fully meets the quality and safety requirements of AAPM Task Group 142 for daily linear accelerator checks. All results are recorded and easily retrievable for Medical Physicist and Administrator review.
