In this study, we focus on differences in the geometric morphology of muscles and aim to identify the optimal surrogate cross-section that shows the highest correlation with total muscle volume using multiplanar reconstruction (MPR) images generated from MRI data. Specifically, the gluteal muscles (gluteus maximus, gluteus medius, and gluteus minimus) will be analyzed as representative radial muscles, while the thigh muscles (e.g., quadriceps femoris and hamstrings) will be analyzed as representative fusiform muscles. Instead of limiting the analysis to conventional axial cross-sections, multiple candidate planes aligned with the muscle fiber direction will be generated. By evaluating how different combinations of plane position and orientation affect the accuracy of muscle volume estimation, the optimal surrogate cross-section for each muscle morphology will be determined.
