A patient example of the liver population model deforming into the patient specific exhale and inhale liver using MORFEUS deformable algorithm to generate the liver population motion model. [(a) and (b)] The liver population exhale model (black mesh) is deformed into the patient’s exhale model (black solid volume). [(c) and (d)] The resulting population-patient exhale liver model (light mesh) is deformed into the patient’s inhale liver (light solid volume). This process generated patient specific deformation maps from the exhale to inhale respiratory states using a common mesh representation for statistical and verification analysis.
