Application of Time-Lapse Imaging Technology and Artificial Intelligence in ART

摘要: 准确评估胚胎发育对于辅助生殖技术(ART)成功至关重要。传统方法多基于主观的胚胎形态学评估,缺乏客观性和实时性。时差成像技术(TLT)提供更稳定的培养环境,实现胚胎发育的动态监测,分析和建模不同发育时期的动态学参数,用于预测胚胎的植入潜力。然而,动态学参数通常需要人工标注,引入主观干扰,数据模型分析能力差异较大,与实际情况相差甚远,尤其在染色体整倍性分析方面表现较弱。随着人工智能(AI)的不断发展,TLT与AI的结合提供了减少TLT人工标注时间、提高胚胎植入率和染色体整倍性预测等方面的可能性。旨在探讨TLT结合AI在形态学和动态学参数方面对胚胎植入潜力和染色体整倍性的应用。Abstract: Accurate assessment of embryo development is of paramount importance for the success of Assisted Reproductive Technologies (ART). Traditional methods predominantly rely on subjective embryo morphological evaluations, lacking objectivity and real-time capabilities. Time-lapse Technology (TLT) offers a more stable incubation environment, facilitating dynamic monitoring of embryo development, analysis, and modeling of dynamic parameters during different developmental stages for predicting embryo implantation potential. However, dynamic parameters often require manual annotations, introducing subjective bias and exhibiting significant disparities in data modeling capabilities, deviating from real-world scenarios, especially in the analysis of chromosomal ploidy. With the continuous advancement of Artificial Intelligence (AI), the integration of TLT and AI holds promise in reducing manual annotation time in TLT, enhancing embryo implantation rates, and chromosomal ploidy prediction. This review aims to explore the application of TLT combined with AI in morphological and dynamic parameters for assessing embryo implantation potential and chromosomal ploidy.
