The diaphragm plays a crucial role in respiratory mechanics. However, commonly used image acquisition methods are limited by position and breath hold duration. We developed a novel MR protocol for scanning the diaphragm in an upright low-field MR scanner and analysis tools to investigate the impact of posture and breath hold state on its morphology.
