研究目的:

超声成像技术其快速性、便捷性以及可重复性越来越广泛地应用于危急重症患者的诊疗。但可靠图像和诊断的获取存在“操作者依赖”现象,基于半监督和生成对抗学习的人工智能技术可望有效使用已有样本标签,提升系统的泛化性能和准确率,实现跨领域 (如自然图像到超声图像)或跨组织器官(如非腹部创伤到腹部创伤超声图像)的知识转移,从而解决超声影像智能分析的难题。  

Objectives of Study:

Ultrasound imaging technology (Ultrasound) is increasingly being used in the diagnosis and treatment of critically care patients because of its speed, convenience, and repeatability. However, the acquisition of reliable images and diagnosis exists the phenomenon of "operator dependence". Artificial intelligence technology based on semi-supervised and generative adversarial learning is expected to effectively use existing sample labels, improve the generalization performance and accuracy of the system, and realize knowledge transfer across domains (such as natural images to ultrasound images) or across tissues and organs (such as non-abdominal trauma to abdominal trauma ultrasound images). The problem of ultrasonic image intelligent analysis can be solved.
