gafchromic™ pnt-dos™ device

A new film-based solution for point and skin dosimetry measurements

Gafchromic™ pnt-dos device is a New FDA/CE compliant Cl film-based solution for doing point dosimetry and skin dosimetry measurements providing accurate, reliable, and easy to use dosimeter for many medical dosimetry applications. When used on a patient, or with a phantom, in radiotherapy and diagnostic radiology applications, gafchromic™ in-vivo dosimetry provides verification of the radiation to confirm the primary dose calculation method for quality control.

Film-based In-Vivo dose measurements offer several advantages over other dosimetry systems.

• • Precise and accurate dose values with consistent accuracy to tolerance ranges: Using the same technology as Ashland’s gafchromic™ films, the highest resolution and accurate dosimeter in the market, gafchromic™ pnt-dos™ has shown to be able to produce accurate reproducible data within +/-1 cGy for low dose range (10-80 cGy) and +/- 5% for high dose ranges (80 cGy to 450 cGy).
  • High spatial resolution, allowing for detailed dose measurements in two dimensions.: gafchromic™ pnt-dos™ device, like Ashland’s other gafchromic™ films, have an improved uniformity of active material providing a high-resolution image when analyzed using filmQA™ pro software using a high-resolution scanner. The software analyzes full area of the gafchromic™ pnt-dos™ to determine the dose delivered with high accuracy and reproducibility. 
  • Relative ease of handling and analyzing, making it convenient for dose measurements: gafchromic™ pnt-dos™ device utilizes an adhesive layer on the back of the device allowing users to easily stick the device to a patient or phantom for the test ensuring the device will not move causing errors. Each gafchromic™ pnt-dos™ device is serialized using a 2-D barcode that can easily be scanned. When scanned into the Point dose module of filmQA™ pro v8, users will be able to easily track and manage use of their gafchromic™ pnt-dos device. Finally, inherent properties of gafchromic films make them nearly energy independent. Users don’t have to worry about these factors as part of treatment planning and still receive highly reproducible results. Just peel, stick, irradiate, analyze. That’s it. 

Gafchromic™ pnt-dos™ device is manufactured as a single-use device when strictly following the procedures outlined in the instructions for use (IFU) to ensure optimal performance, accuracy, and patient safety. Due to the potential for changes in dosimeter performance with accumulating life-time dose, Ashland does not support reuse of the In-Vivo Dosimeter for use with patients. 

When used for calibration and quality control (QC), the dosimeter may be used in accordance with the recommended replacement schedule.
