TrueView LogoModus QA is pleased to announce the new radiochromic 3D dosimeters for research into 3D dosimetry are now compatible with red and green light sources.

TruView™ 3D Dosimeters are stable, fast and reusable.

TrueView™ is a multi-use radiochromic 3D dosimeter designed for on-site read-out by optical CT. Applications for this 3D dosimeter include IMRT, VMAT, SRS and SBRT.

TrueView™ is stable in storage for up to 30 days. The signal must be read out between 60 and 90 minutes after irradiation which requires an optical CT scanner on-site. TrueView™ can be used again 48 hours after irradiation. It is made with a low scatter substrate that works well with the Vista™ Optical CT Scanner as well as fast laser optical CT scanners.

Key Features

  • Linear
  • Fast
  • Reusable
  • Clear
  • 95% Water

Benefits

  • Dose response is linear to 20 Gy
  • Optical CT readout between 60 and 90 minutes after irradiation
  • Diffusion causes homogeneity within 48 hours after irradiation dosimeter can be used multiple times
  • Low scatter substrate is suitable for cone beam as well as laser optical CT scanners
  • Near tissue equivalence (5% solids), specific gravity 1.01, no high Z elements

HOW THEY WORK

  • Store 3D dosimeters in a refrigerator, but do not freeze
  • Irradiate and scan below 22 °C
  • Scan at 585 - 590 nm or 620 - 630 nm
  • Avoid direct sunlight and temperatures above 30 °C
  • Scan before and after irradiation for best results
  • Absorbed dose is directly proportional to the change in optical attenuation
  • Scan between 60 and 90 minutes after irradiation
  • Diffusion causes homogeneity in about 48 hours after irradiation
  • Background optical attenuation will rise after each use
  • Refractive index matching liquid can be darkened with food colouring to optimize the dynamic range of the scanner
  • Dose sensitivity is linear up to 20 Gy, dose can be delivered in multiple fractions
  • 3D dosimeter properties are consistent within one batch
  • 3D dosimeter are mildly acidic with low toxicity

Vista™ is a fast cone beam optical CT scanner designed for True 3D Dosimetry.

Vista™ is used for on-site or remote scanning of 3D dosimeters including ClearView™ and TruView™. The Vista™ Optical CT Scanner includes software for acquisition, reconstruction, and display of 3D optical CT images. Images from Vista™ are analyzed in VistaAce™ software as well as a variety of 3rd party software applications.

ClearView™ is a single-use radiochromic 3D dosimeter designed for remote or on-site read-out by optical CT.

Applications for this 3D dosimeter include SRS, SBRT and 3DDaaS. ClearView™ is stable in storage for over 90 days and the signal is stable for more than a week after irradiation. It is made with a low scatter substrate that works well with the Vista™ Optical CT Scanner as well as laser optical CT scanners.

For customers using the Vista™ Optical CT scanner, VistaAce™ 3D Dosimetry Software is available to analyze, compare and evaluate dose measurements in True 3D.

It includes a full suite of tools for the registration and dose scaling of measured and planned dose distributions plus the calculation of conformity indices and gamma maps in 3D.
