Abstract
In a system of X-ray diagnosis for angiographic examinations, the passage of a contrast medium is detected by its physiological effects such as the rise in the temperature of the cutaneous tissues, by means of thermocouples positioned on the patient's body. The signals from the thermocouples are processed in a device which gives forward motion signals for a panel supporting the patient and signals for triggering the shooting in such a way that the radiological image includes an image of the contrast medium.
