A determination method for reinitialization of a temporal sequence of fluoroscopic images of an examination region of an examination object is provided. The examination region comprises a vascular system including arteries and/or veins. An acquisition time is assigned to each of the images representing a given distribution of a substance in the examination region at the acquisition time. A computer receives the temporal sequence of the images, determines an evaluation image corresponding spatially on a pixel-by-pixel basis to the images, and calculates a differential value between a pixel of the evaluation image at a time and a pixel at a preceding time during a time characteristic of the sequence. A reinitialization of the temporal sequence of the images is performed at a specific time and thereafter the determination method is started over and/or repeated. The specific time is determined as a function of at least one previously calculated differential value.
A method for reinitializing a temporal sequence of fluoroscopic images of an examination region of an examination object, wherein the examination region comprises a vascular system including arteries and/or veins as blood vessels, comprising:
A computer program stored on a non-transitory computer readable medium and executable by a computer for reinitializing a temporal sequence of fluoroscopic images of an examination region of an examination object, wherein the examination region comprises a vascular system including arteries and/or veins as blood vessels, comprising:
