超分辨超声（SR-US）是一种可在高空间分辨率下捕捉微血管结构与血流的强大成像技术。然而，微泡（MB）精确定位仍是关键挑战，因定位误差会传递至后续超分辨流程，影响整体性能。本文探索集成学习技术在提升微泡定位中的潜力，通过提高检测灵敏度并降低误报率来优化定位。研究评估了集成方法在可变形检测变压器（Deformable DETR）网络生成的体内及模拟输出上的有效性。结果表明，集成策略显著提升了微泡检测的精确率与召回率，并为该技术在SR-US中的应用提供了深入见解。
原文摘要 · Abstract (English)
Super-resolution ultrasound (SR-US) is a powerful imaging technique for capturing microvasculature and blood flow at high spatial resolution. However, accurate microbubble (MB) localization remains a key challenge, as errors in localization can propagate through subsequent stages of the super-resolution process, affecting overall performance. In this paper, we explore the potential of ensemble learning techniques to enhance MB localization by increasing detection sensitivity and reducing false positives. Our study evaluates the effectiveness of ensemble methods on both in vivo and simulated outputs of a Deformable DEtection TRansformer (Deformable DETR) network. As a result of our study, we are able to demonstrate the advantages of these ensemble approaches by showing improved precision and recall in MB detection and offering insights into their application in SR-US.
