Synchronization of medical imaging systems
First Claim
1. A method for interventional imaging of synchronizing a first dataset with a second dataset, wherein the datasets represent a region of interest in a patient, the first dataset and the second dataset each corresponding to two different types of information on the region of interest, and wherein the datasets are acquired by separate medical systems, the method comprising:
- generating a synchronized signal from a first signal and a second signal; and
aligning the first dataset and the second dataset with the synchronized signal,wherein the first signal and the second signal represent a physiological activity of the patient as measured by respectively, a first device and a second device, one each found on the separate medical systems,wherein the first signal has an acquisition rate that is different from the acquisition rate of the second signal,wherein the first signal and the second signal are recorded by the first device and the second device of the medical systems on a common time scale with the time scale used for acquiring the datasets,wherein the first signal and the second signal are synchronized to the synchronized signal by,determining a time shift between the first signal and the second signal that reflects the different acquisition rates of the first signal and the second signal, andfrom the time shift, setting the origin of the first signal and the second signal on the common time scale, andwherein the origin of the synchronized signal acts as a time reference for the first dataset and the second dataset on the common time scale, and the synchronized signal is partly or fully modulated with an external aperiodic signal generated by a source external to one or the other of the medical systems.

Abstract
A method for interventional imaging of synchronizing a first dataset with a second dataset is provided. The datasets represent a region of interest in a patient, wherein the first dataset and the second dataset each corresponding to two different types of information on the region of interest and wherein the datasets are acquired by separate medical systems. The method comprises aligning the first dataset and the second dataset with at least two signals representing a physiological activity of the patient, the at least two signals having been recorded by the medical systems on a common time scale with the time scale used for acquiring the datasets.
