Patent ID: 8483455

Claim:
A method to evaluate a time series of images in a test bolus measurement comprising: making a time series of two-dimensional evaluation images available to a processor, said time series of two dimensional evaluation images being selected from the group consisting of a series of two-dimensional images acquired from an examination subject beginning with administration of a contrast agent to the subject, and a derived time series of two-dimensional images derived from said time series of two-dimensional images; through said processor, at least semi-automatically determining at least one point representing a contrast agent signal associated with a blood vessel in at least one of said evaluation images, and transferring said at least one point to other evaluation images in said time series of two-dimensional evaluation images; in said processor, for each blood vessel having said at least one point associated therewith, automatically determining a plurality of constituents of a temporal contrast agent course curve, said constituents being selected from the group consisting of said at least one point in each of said at least one evaluation image and said other evaluation images, and a region around said at least one point in said at least one evaluation image and said other evaluation images, and automatically deriving said temporal contrast agent course curve from said constituents; through said processor, determining, from said temporal contrast agent course curve, at least one item of contrast agent information that affects a temporal workflow of a subsequent examination of said examination subject using contrast agent and making said at least one item of contrast agent information available in electronic form at an output of said processor; in said processor, automatically implementing a plausibility check for said at least one point to determine whether said at least one point is plausible as a point exhibiting a contrast agent signal; and implementing said plausibility check by comparing a signal value of said at least one point to respective signal values of said at least one point in temporally adjacent images in said series of evaluation images.
