Classification: CPC A  G | IPC A  G

Claim 26:
27. A method, comprising:
outputting a first advance signal at a first defined time before a start time for starting manual administration of a contrast agent to a body;
outputting a first indication instructing performance of the manual administration of the contrast agent, the outputting the first indication outputs the first indication at the start time for starting the manual administration of the contrast agent;
performing a monitoring scan including,
detecting first medical imaging data corresponding to x-ray data,
producing first images of a body based on the x-ray data, and
detecting a signal level at a defined position in the body from the first images;

computing a first time interval based on a characteristic time interval between the start time for starting the manual contrast administration and a time at which the signal level at the defined position in the body reaches a threshold level;
outputting a second advance signal after computing an end time for ending the manual administration of the contrast agent, the second advance signal being a color-coded signal or an audio signal, the end time for ending the manual administration of the contrast agent preceding an end of an x-ray imaging scan of the body by the first time interval;
outputting a second indication instructing termination of the manual administration of the contrast agent, the outputting the second indication outputs the second indication at the end time for ending the manual administration of the contrast agent, and the second advance signal being output at a second defined time before the second indication is output; and
timing operation of an x-ray imaging device for performing the x-ray imaging scan based on the start time for starting the manual administration of the contrast agent, a timing of at least one of the start time for starting the manual administration of the contrast agent, a beginning of the x-ray imaging scan or the end of the x-ray imaging scan being based on user-selected points in time, and the user-selected points in time being based on an examination protocol, a contrast agent or a patient characteristic.
