Cineradiography Observations of Human Subjects during Transverse Accelerations of +5GX and +10GX

摘要

X-ray motion pictures were recorded for five human subjects during transverse accelerations of +5Gx and +10Gx on the Johnsville centrifuge. Quantitative measurements of change in A-P chest diameter and heart position were made from photographic prints of the films. A slight but significant posterior displacement of heart position could be demonstrated when compared to change in the A-P chest diameter.
