Real-Time Detection of Hemothorax and Monitoring its Progression in a Piglet Model by Electrical Impedance Tomography: A Feasibility Study

Figure 7

EIT imaging of the hemothorax procedure in the piglets. (a) A series of reconstructed EIT images of the eight subjects before and during the entire course of blood injection. (b) The individualized region of interest (ROI) in each of the subjects where blood was injected. (c) The statistical comparison of regional impedance variation (RIV) for all the subjects before and after blood injection. (d) The linear regression analysis between RIV in EIT images and the volume of blood injection for all eight piglets as well as for the pooled data. Each line represents a single piglet marked with a unique color and a symbol. The bold blue line denotes the mean relationship between RIV and blood volume for the eight piglets.
