An experimental single photon emission computed tomograph method for dynamic 2D fluid flow analysis

We propose a transportable Single Photon Emission Computed Tomograph (SPECT) device dedicated to the reconstruction of a radioactive tracer distribution in a process. The experimental device is realized with 36 collimated sodium iodide detectors mounted around a bi-dimensional cylindrical box which simulates a mixing reactor vessel. The reconstruction is based on a statistical algorithm applied to a small number of views and detectors. Dynamic acquisitions coupled to video monitoring were performed after the injection of radioactive and dye tracers in the vessel. The analysis of first results show that the experimental SPECT method, based on a limited number of detectors, is hopeful for industrial needs.
