Figure 5From: Determination of patient-specific internal gross tumor volumes for lung cancer using four-dimensional computed tomographyStage III tumors. (a) Volumetric underestimation for each IGTV based on IGTVMIP, IGTV2Phases, and IGTVMIP-Modified relative to the IGTVAllPhases. (b) Volumetric overestimation for each IGTV based on IGTVMIP, IGTV2Phases, and IGTVMIP-Modified relative to the IGTVAllPhases. (Note: IGTV2Phases is a subset of IGTVAllPhases, hence the volumetric overestimation for IGTV2Phases is always equal to zero.)Back to article page
