Understanding morphological and positional changes of torso organs due to posture, breathing, and body size variation using Upright 0.5T Open MR

Motivation: To protect the vital torso organs from ballistic and stab threats, personal protective equipment needs to ensure optimal coverage. Such optimisation should consider the variation in organ position and morphology due to change in body size, posture and breathing patterns across population, rather than following an universal approach. Goal(s): To conduct a proof-of-concept study exploring the applicability of Upright Open 0.5T MR scanner in understanding internal organ morphometry. Approach: We aim to quantify the change in organ positions and boundaries as compared to fixed external markers for three body sizes and two breathing patterns while participants are in supine and standing position. Impact: Understanding the changes in torso organ morphology and position using upright and supine scans at Open MR could improve the fit, form and anatomical coverage of personal protective equipment and protect security and defence professionals against ballistic and stab threats.
