A Hybrid Transformer-Deep Learning Model for Improved Cardiac MRI Left Ventricle Segmentation

Cardiac left ventricle segmentation is crucial in diagnosing and managing various cardiac diseases. Accurate and efficient segmentation c an leadtop recise e valuations of left ventricular size, shape, and function, ultimately enhancing clinical outcomes. With the advent of deep learning, transformer architectures have emerged as powerful tools for medical image segmentation. This study introduces an innovative hybrid architecture that combines the strengths of the transformer model with established deep-learning models. Our approach demonstrates superior performance in cardiac left ventricle segmentation from MRI images, achieving near-perfect accuracy and significantly outperforming traditional models in both Dice coefficient and Intersection over Union (IoU) metrics. These results confirm the model's ability to capture complex image dependencies while maintaining class balance, marking a notable advancement in cardiac MRI segmentation.
