Tetrazolium-based 3D gellan gum gel dosimeters have been reported previously and tested at several sites. They show no image diffusion and excellent stability; however, the dose sensitivity of the current commercial product, ClearView (TM), is relatively low for routine clinical applications. Here we report initial testing of a second generation product with increased sensitivity and retained non-diffusive properties. This formulation has a 25% increase in sensitivity relative to ClearView (TM). However, the sample has a higher initial attenuation and the background attenuation increases faster than ClearView (TM). The composition was tested in a 1-liter sealed container using a 2x2 cm, 6MV, x-ray beam, and show agreement between Monte Carlo simulation and measurements.
