We developed upright CT for whole-body scan. It has the same physical characteristics as a conventional CT, requires only 2/3 of the space of a conventional CT, and can be performed with a workflow similar to that of radiography. We have revealed that the brain and pelvis of healthy volunteer, which were previously thought to remain unchanged in position, descend in the upright position, gradually revealing the structure of the human body under gravity. In particular, the veins show different capacitance changes between the upright and supine positions depending on the area. It is also possible to evaluate the muscle volume of each area, such as pelvic floor laxity, the trunk and thighs, and to suggest ways to exercise according to individual muscle atrophy. As for diseases, hernias and organ prolapse can be evaluated quantitatively, and early detection of musculoskeletal diseases such as knee osteoarthritis is also possible. Furthermore, dynamic functions such as swallowing, respiration, urination, and gait can be evaluated and related pathologies can be detected at an early stage. Through upright CT, we hope to contribute to the needs of an era of health and longevity.
