Abstract
A photogrammetry technic has been developed to examine the trunk's movement during quiet breathingand under different breathing manoeuvres: a rectangular network projected on the illuminated surface of the trunk and on a screen behind the subject examined . By taking a series of pictures from two directions we can determine the position of each surface points. Construction of horizontal slide surfaces at different phases of the breathing cycle made possible to calculate the volume change , the velocity of displacement of certain surface points or the movement of a representative mamillar line , where several types of breathing can be characterized.
