BeamCheck

LINAC Performance Testing Panel

BeamCheck employs a dual-layer interleaved array of 759 ionization chambers, providing maximum detection coverage of 31.4 × 31.4 cm. The X/Y-axis chamber spacing is 2 mm, complemented by four dedicated detection columns for MLC monitoring with 2.5 mm chamber spacing. Built-in battery with automatic temperature/pressure compensation, integrated with XBeam for automated measurement and protocol-based evaluation, efficiently completing daily/weekly/monthly LINAC QA.

Key Features

Multi-Metric Coverage In a Single Beam

Simultaneously acquires OAR curves in X/Y directions during a single beam delivery, automatically analyzing periodic QA metrics including output dose, flatness, symmetry, field boundaries, and beam quality—simple and efficient.

Single-Device Coverage for Full Cycle Needs

Aligned with TG142 radiotherapy quality control standards, one device handles daily, weekly, monthly accelerator inspections and partial annual checks, directly replacing the multi-device setup of “morning checker + monthly check matrix + annual check water tank”.

Fully Automated Workflow

Built-in battery eliminates power constraints, enables rapid positioning, and automatically identifies dose anomalies or mechanical faults through “automatic data collection - intelligent analysis and diagnosis”.

Compatibility with Mainstream Models and Multi-Angle Scenarios

The head-mounted accessory is compatible with leading accelerators like Elekta and Varian. It can be suspended beneath the head and rotate 360° with the gantry, enabling multi-angle dose measurements.

Energy Characteristic Analysis

Calculates energy characteristic parameters for photon and electron beams, effectively verifying radiation energy stability.
