High-resolution reconstruction of fluorescent inclusions in mouse thorax using anatomically guided sampling and parallel Monte Carlo computing.
Abstract
We present a method for high-resolution reconstruction of fluorescent images of the
mouse thorax. It features an anatomically guided sampling method to retrospectively
eliminate problematic data and a parallel Monte Carlo software package to compute
the Jacobian matrix for the inverse problem. The proposed method was capable of resolving
microliter-sized femtomole amount of quantum dot inclusions closely located in the
middle of the mouse thorax. The reconstruction was verified against co-registered
micro-CT data. Using the proposed method, the new system achieved significantly higher
resolution and sensitivity compared to our previous system consisting of the same
hardware. This method can be applied to any system utilizing similar imaging principles
to improve imaging performance.
