X-ray QA dosimeter myQA StarTrack³

Overview
myQA StarTrack³ is a high‑definition 2D detector array for linac Machine QA. It provides a single‑setup solution to capture comprehensive photon and electron beam data across a 34 × 34 cm active area for commissioning, monthly and annual QA tasks without warm‑up or complex infrastructure.

Key benefits

• Precision: High‑definition ion chamber array delivering water‑tank comparable accuracy (±0.5%) for output and profile measurements.
• Coverage: Full field coverage (≥30×30 cm including tails) enabling real‑time beam steering, fast verification and trending.
• Efficiency: Single quick measurement captures output, beam quality (TPR20,10 / R50), flatness, symmetry, field size and penumbra — monthly QA workflows completed in minutes including setup.

Features

• Single detector setup: from placement to verified measurement in under five minutes.
• Wireless data transfer for cable‑free workflows; optional Ethernet LAN available.
• Rechargeable battery with charger included; 9V power supply option for alternative power.
• Laser markers for accurate and repeatable alignment.
• Integrated energy verification plates for photon (TPR20,10) and electron (R50) checks in under a minute.
• High spatial resolution: 2.5 mm resolution at field edges; 5.0 mm center‑to‑center on primary axes; 7.1 mm on diagonals for precise profile and penumbra assessment.

At a glance — highlighted capabilities

• Cutouts for secure handling and transport.
• Light field check with quantitative results available in the software.
