Angularly Resolved Deep Brain Fluorescence Imaging Using a Single Optical Fiber

Figure 4

Results from phantom experiments compared to simulations measuring resolution in vertical and radial direction. For the absorption coefficient, , four data points were collected at 1.0, 3.0, 5.0, 7.0cm⁻¹. Our estimation for the value of in brain tissue is 3.36 cm⁻¹. Phantom results are within 20% of our simulations (Left). For the reduced scattering, , four data points at 10.0, 26.0, 43.0, 60.0 cm⁻¹ were collected. The value of we used for simulations was 23.2 cm⁻¹. These results are within 25% of the simulated values for the FWHM.
