Latest Patents

Among his latest patents, two stand out for their groundbreaking approach and potential impact on medical practice.

1. **Method and device for magnetic resonance imaging data acquisition guided by physiologic feedback**: This patent describes an adaptive real-time radial k-space sampling trajectory (ARKS) that responds to physiologic feedback signals, aimed at reducing motion effects during MRI scans and ensuring uniformity in sampling. The process involves continuously matching the most recent electrocardiogram (ECG) signals to previous records, which allows new radial k-space locations to be identified efficiently. These MR signals can then be combined using either multi-shot or single-shot radial acquisition schemes, leading to enhanced MRI imaging quality.

2. **Assessment of hemodynamic function in arrhythmia patients**: This innovation addresses the limitations of electrocardiogram (ECG)-gated cardiac MRI in capturing hemodynamic changes during arrhythmic events. The patent emphasizes that ejection fraction values are dependent on acquisition methods. By integrating real-time volume measurements with ECG recordings, the technology categorizes beat morphologies, facilitating a more comprehensive assessment of ventricular function during instances of arrhythmia.
