ClearView™ is a non-diffusing, radiochromic hydrogel dosimeter designed for verification of advanced radiation therapy techniques including SRS. Visualizing the intricate detail of complex dose distributions and multiple lesion dosimetry, ClearView™ aids users in confirming planned treatments are delivered accurately.
Principles of radiochromic 3D dosimetry are analogous to film (2D) dosimetry. Dose scaling with ClearView™ is achieved by using a reference dose delivery in the same dosimeter or irradiation of another dosimeter from the same manufacturing batch.
ClearView™ is intended to be used as part of an integrated 3D dosimetry system which includes an optical CT scanner such as Vista™ 16, and analysis software, Vista ACE™ (in development).
Stability: Chemistry is stable for over 60 days prior to irradiation under recommended storage conditions. The signal is geometrically stable at any time after irradiation. For best dosimetric results, optical scanning is recommended between 1 and 24 hours after irradiation.
Linear Response: Dose response is linear within range of 0 to 80 Gy, providing utility in SRS applications
High Resolution: Gel is accurate to a sub-micron level
Clear: Low scatter substrate makes ClearView™ ideal for optical cone beam CT imaging
90% Water: Near tissue equivalence provides patient-like testing environment (see table for values)
