Figure 7
Essentials for arteriography. Note that the chronometer measures circulation time by intravenously injecting 5 cc of ether in 20 cc of saline and by detecting the odor in the patient’s breath [10].
Figure 8
Catheter introduced into the aorta. The ascending aorta, the arch with all the brachiocephalic branches, and the descending aorta are visualised [12].
Figure 9
The sinus of Valsalva and semilunar valves are clearly seen. The two coronary arteries are also visible [13].

Figure 13
Direct radio-cinematography. By means of a powerful high-tension generator having a constant throughput, a fluorescent screen is illuminated, and with a motion picture apparatus, it was possible to produce on a small-size film (12 × 14 cm) at least 16 pictures per second. General view (A). Detail of the Gevaert’s applied film (B) [21].

The diagram shows the approaching board with angle board, side guides, lead shield for film, and personal protection [23].
