Imaging device and method for operating an imaging device
First Claim
1. An imaging device for generating successive tomograms of an object, comprising:
- a radiation source;
a detector;
a positioning unit; and
a control unit configured to control the positioning unit and to evaluate the recorded data of the detector, the control unit being configured to match a contrast medium protocol, in which parameters for contrast medium administration are stored, intended for use in an examination by a contrast medium device, to a scan protocol provided for the examination, in which operating parameters for generating the successive tomograms are stored, avoiding unnecessary administration phases, whereinthe control unit is configured to match the contrast medium protocol automatically to the scan protocol,the control unit is configured to determine, before the beginning of the examination, a conflict situation between scan protocol and contrast medium protocol relating to different time durations for the scan and contrast medium protocols,the examination includes all of the tomograms generated by the imaging device of the object such that none of the tomograms of the object are generated prior to the control unit determining the conflict situation,the control unit is configured to drive the contrast medium device, andthe control unit is configured to,detect a distance of the field of examination from the location of a contrast medium administration,calculate a correction time based on a rate of propagation of the contrast medium and the detected distance if the end of scanning is reached,shorten the contrast medium administration based on the calculated correction time, andstop the contrast medium protocol immediately before or on reaching the end of the scan protocol.

Abstract
An imaging device is disclosed for generating successive tomograms of an object. In at least one embodiment, the imaging device includes a radiation source, a detector, a positioning unit and a control unit for controlling the positioning unit and for evaluating the recorded data of the detector. In at least one embodiment, it is provided that the control unit is set up for matching a contrast medium protocol, in which parameters for contrast medium administration are stored, provided for examinations in a contrast medium device, to a scan protocol provided for the examination, in which operating parameters for generating successive tomograms are stored, for preventing unnecessary administration phases. This provides for a contrast medium examination with the least possible contrast medium administration.

8. A method for operating an imaging device including a radiation source, a detector and a positioning unit, the method comprising:
matching a contrast medium protocol, in which parameters for contrast medium administration are stored and intended for use in an examination by a contrast medium device, to a scan protocol provided for the examination, in which operating parameters for generating successive tomograms are stored, preventing unnecessary administration phases, wherein the matching automatically adapts the contrast medium protocol to the scan protocol, the matching determines, before the beginning of the examination, a conflict situation between scan protocol and contrast medium protocol relating to different time durations for the scan and contrast medium protocols, and outputs to a display unit a corresponding warning dialog with a request for the matching, the matching detects a distance of the field of examination from the location of a contrast medium administration, the matching calculates a correction time based on a rate of propagation of the contrast medium and the detected distance if the end of scanning is reached, the matching shortens the contrast medium administration based on the calculated correction time, the examination includes all of the tomograms generated by the imaging device of the object such that none of the tomograms of the object are generated prior to the matching determining the conflict situation, and the contrast medium protocol is stopped at least one of immediately before and on reaching the end of the scan protocol. - View Dependent Claims (9, 10, 11, 12, 13, 14)
