Angularly Resolved Deep Brain Fluorescence Imaging Using a Single Optical Fiber

Figure 9

(a) In vivo results. 3D image reconstruction of a section of the brain under test. (b) Following the path of the fiber, the maximum expression is found at approximate depth of 6.6mm from the surface. (c) Following the rotational path of the fiber, we found the maximum expression closest to the fiber tip at approximately 135°. (d) Data collected with our system and presented using gamma correction factor of 6.
