ABSTRACT:
Tomodensitometer, particularly for examining bodies which perform cyclic movements such as the heart and the pericardiac tissues. To eliminate blurring caused by the heart movements the rotation of the radiodensitometric measuring system is synchronized with the movements in such a way that at the time when the periodic movement of the tissue is at its maximum amplitude the projection direction substantially coincides with the direction of the movement and that the start and finish of the measurements coincide respectively with the start and finish of the immobility periods adjacent to the movement period.
