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.
- 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.
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
