Base OTL38-equivalent reference set (Lung)



  1. OTL38-equivalent Concentration Sensitivity Target (Lung)
  2. OTL38-equivalent Depth Sensitivity Target (Lung)
  3. OTL38-equivalent Resolution Target (Lung)

All base optical properties (reduced scattering and absorption) are designed to mimic lung tissue at ~770-800 nm

Set available in standard size


The reference targets in this kit are designed to mimic OTL38 (pafolacianine) fluorescence fluorescence in the presence of lung-equivalent optical properties for reduced scattering and absorption in the NIR.  The concentration sensitivity target provides a method to determine an imaging system’s range of linearity as well as an estimate for the noise floor and saturation point. The depth sensitivity target contains 1000 nM OTL38-equivalent material at depths of 0.5-6mm under non-fluorescent tissue-mimicking material, which simulates in vivo imaging environments. The fluorescence resolution target uses a negative USAF1951 test target and 1000 nM OTL38-equivalent material to provide an estimate of the imaging system’s optimal resolution to determine the resolvable feature size in fluorescence mode.
