Abstract
A method is for medical imaging of a patient using a medical imaging system with ECG triggering. In an embodiment, the method includes capturing a respiration signal of the patient including n respiration cycles; concurrently capturing an ECG signal of the patient including m heartbeat intervals; determining a respiration-dependent heartbeat model based upon the n respiration cycles and the m heartbeat intervals; specifying at least one trigger time-point based upon the respiration-dependent heartbeat model; and starting the medical imaging at the specified trigger time-point.

A method for medical imaging of a patient using a medical imaging system with ECG triggering, the method comprising:
- capturing a respiration signal of the patient, the respiration signal including n respiration cycles;
- concurrently capturing an ECG signal of the patient, the ECG signal including m heartbeat intervals;
- determining a respiration-dependent heartbeat model based upon the n respiration cycles and the m heartbeat intervals by dividing the respiration signal into at least two respiration phases and dividing the m heartbeat intervals into at least two heartbeat ranges, each of the at least two heartbeat ranges corresponding to a respiration phase of the at least two respiration phases;
- specifying at least one trigger time-point based upon the respiration-dependent heartbeat model;
- and
- starting the medical imaging at the at least one trigger time-point specified;
- wherein the respiration-dependent heartbeat model is initially determined while the patient is at rest, such that the at least two respiration phases include an inhalation phase and an exhalation phase;
- and
- wherein the respiration-dependent heartbeat model includes modifications to a breathing pattern of the patient as additional phases of the at least two respiration phases.
A computing unit for medical imaging of a patient using a medical imaging system with ECG triggering, the computing unit being designed to
- capture a respiration signal of the patient, the respiration signal including n respiration cycles;
- concurrently capture an ECG signal of the patient, the ECG signal including m heartbeat intervals;
- determine a respiration-dependent heartbeat model based upon the n respiration cycles and the m heartbeat intervals by dividing the respiration signal into at least two respiration phases and dividing the m heartbeat intervals into at least two heartbeat ranges, each of the at least two heartbeat ranges corresponding to a respiration phase of the at least two respiration phases;
- specify at least one trigger time-point based upon the respiration-dependent heartbeat model;
- and
- start the medical imaging at the at least one trigger time-point specified;

- and
- wherein the respiration-dependent heartbeat model includes modifications to a breathing pattern of the patient as additional phases of the at least two respiration phases.
