From: Development of a dynamic myocardial perfusion phantom model for tracer kinetic measurements
A selection of seven myocardial perfusion imaging series aiming to highlight the overall phantom development and evaluation process. The image cross sections and polar maps present the accumulated radiotracer distribution inside the phantom, which is a static representation of a dynamic measurement. Note that the relative color scale is determined by default for each individual measurement and is therefore not linked between measurements. In these measurements, mimicking of radiotracer uptake, normal perfusion and perfusion deficit was examined using different parameter settings. Settings include the type and mass of sorbent (s) utilized to mimic myocardial tissue, and the amount of volume flux (Φ) directed through the myocardial segments (MYO). D2#4 stands for the measurement day and number, respectively.
