ABSTRACT:
In a diagnostics system wherein a radiological image is generated of a patient who has been injected with a contrast agent, the arrival of the contrast agent bolus at the imaging site is identified either directly by detecting the contrast agent, or indirectly by detecting a dye injected with the contrast agent, so that a synchronization of the imaging exposures with the arrival of the contrast agent can be assured. If a dye is used, the dye can be an optically detectable dye which is injected via the contrast agent syringe in addition to the contrast agent. A densitometer identifies the arrival of the contrast agent or of the dye at a predetermined location of the patient, and controls triggering of the exposures.
