Method for determining ECG-triggered recording times for imaging to support interventional and diagnostic cardiac procedures

A method for determining a plurality of ECG-triggered recording times for a cardiac imaging recording of a patient, comprising:

• recording a plurality of images of a heart of the patient;
• assigning the images to specific cardiac phase times;
• comparing the images for determining a similarity measure;
• identifying a group of images having the similarity measure in a predefined area;
• and
• specifying the cardiac phase times associated with the images in the group as the ECG-triggered recording times to be used in the cardiac imaging recording.

A method for performing a moving-target cardiac imaging of a patient, comprising:

• recording a plurality of images of a heart of the patient;
• assigning the images to specific cardiac phase times;
• comparing the images for determining a similarity measure;
• identifying a group of images having the similarity measure;
• specifying the cardiac phase times associated with the images in the group as the ECG-triggered recording times;
• and
• performing the moving-target imaging based on image recordings recorded at the ECG-triggered recording times.

A medical device for determining a plurality of ECG-triggered recording times for a cardiac imaging recording of a patient, comprising:

• a medical imaging device that recodes a plurality of images of a heart of the patient;
• and
• a control device that:
• assigns the images to specific cardiac phase times,
• compares the images for determining a similarity measure,
• identifies a group of images having the similarity measure, and
• specifies the cardiac phase times associated with the images in the group as the ECG-triggered recording times to be used in the cardiac imaging recording.
