Radiation monitoring firm Landauer of Glenwood, IL, has launched a new system for monitoring radiation dose delivered to patients.
The company's microStar system is based on optically stimulated luminescence (OSL) dosimetry, and uses Landauer's proprietary nanoDot technology to measure skin entrance dose. The company believes the product is superior to alternatives based on thermoluminescence dosimeters (TLD) and diodes.
Landauer's nanoDots have no dependence on irradiation angle or energy, and require no annealing or other labor-intensive preparation, according to the company. In addition, the nondestructive readout of nanoDot OSL dosimeters allows reanalysis, a feature not found in TLD and other dosimetry alternatives. This enables clinicians to record cumulative dose with multiple readings, and archive dosimeter readings for future reanalysis or to create a permanent dose record.
