1D SCANNER™ is an efficient water tank for performing point dose and PDD dosimetry. Use it for annual linac calibration or monthly constancy checks.

Simple, Efficient Water Scanning
1D SCANNER enables dosimetry measurements in water, including output factors, dose calibrations, annual, and routine QA. Collect PDD curves with optional SunDOSE™ software and PC Electrometer™.

Easy, Reproducible Setup
Setup is simple with a single power and data cable connection. Plus, a water surface detection feature automatically sets the dosimetry detector at the water surface, removing subjectivity. Control the tank in-room using the pendant or outside of the room using software.

Meet TG-51 requirements with ease.

Intuitive Software
SunDOSE™ software complements 1D SCANNER with powerful analysis and smart features for enhanced efficiency.

  • Queues and projects for organizing and executing groups of scans, and tracking annual QA and commissioning
  • Multi-scan comparison tool for 1-click quantitative analysis across data sets
  • Searchable database for easy access to data with the ability to share data among users
  • Processing layers for insights into each function along the scanning process, and ability to revert to earlier unprocessed data
