Dr.Ahmad Al-Enzi receives a patent from the U.S. Patent Office for his invention of a left heart chamber simulator, which is the first dynamic lumped model of the left ventricle of the heart. It is designed to simulate a wide range of cardiac diseases and various physiological conditions. This model allows for a realistic assessment of gated cardiac imaging with corresponding electrocardiogram (ECG) signals, which supports image quality control, system performance evaluation, improvement of acquisition and reconstruction protocols, and the study of cardiac diseases.
