本文提出QuantumBoostNet,一种结合经典与量子架构的方法,用于提高心脏超声视图识别准确性,通过两阶段训练及自适应头切换机制解决了医学图像中高噪声问题。
This work addresses the challenge of segmenting heterogeneous multi-center, multi-sequence, and multi-view cardiac MRI images and directly estimating left ventricular ejection fraction (LVEF). The authors propose a novel approach that integrates fine-tuned and frozen foundation models for cardiac MRI. Specifically, the CineMA model is fine-tuned to achieve high-accuracy segmentation of both cine and late gadolinium enhancement (LGE) images, while frozen models extract embedding features that, combined with an attention mechanism, enable multi-instance learning for end-to-end LVEF regression. This method represents the first effective integration of multiple foundation models, overcoming the limitations of single-model approaches. Experimental results demonstrate Dice scores of 0.862–0.902 for cine and 0.621–0.846 for LGE segmentation, with an LVEF estimation mean absolute error of 4.96% and a Pearson correlation coefficient of 0.91.
