1. A pulsatile perfusion image reconstruction method corrected by saline contrast, wherein the method comprises:
obtaining a patient band-pass filtering electrical impedance curve to generate a pulsatile graph;
obtaining a patient synchronous saline contrast impedance dilution curve to generate a saline contrast-based lung perfusion image of a patient;
calculating a ratio of blood flow impedance data in the saline contrast-based lung perfusion image to pulsatile impedance data in the pulsatile graph to generate a correction factor;
generating a pulsatile perfusion image corrected by saline contrast based on the correction factor and the pulsatile graph.
