Small element in-vivo dosimetry system for radiotherapy
Dose Ace

Excellent small RPL glass element using a new manufacturing process has evolved a new sophisticated radiation dosimetry system.

Dose Ace

- Compact radiophotoluminescence (RPL) glass element replacing thermoluminescent dosemeter (TLD) material

- Radiation dosimetry revolution brought by the new material.

- New material meets all the requirements for dosemeter including high accuracy and low readout cost.

- New dosemeter is free from conventional problems with TLD such as complicated handling, damage and toxicity.

Advantages

  • RPL glass element supports an unlimited number of repeated readouts. The reading process is non-destructive contrary to the destructive readout process used in TLD.
  • Homogeneous composition of RPL glass element ensures stable dosimetry.
  • Measurement accuracy is ensured across a wide dose range.
  • Simulation and quality assurance of radiotherapy and diagnostic procedure are easier due to non-destructive automatic readout procedure and results available immediately after testing.
  • Speedy readout process: Up to 20 measurements can be continuously read out in a fully automated process with results immediately available via connected PC for further analysis.

Advantages

Applications

RPL glass dosemeters are stable, accurate, and reliable - suitable for a wide range of applications.

  • Verification of delivered dose in radiotherapy and diagnostic imaging using phantom simulation
  • Studies using small animal irradiation experiments
  • Quality assurance of photon (gamma ray and X-ray) irradiation
  • Compact glass allows accurate localized measurement of dose distribution
