精确分析宽视野荧光图像

利用荧光显微镜的特异性，即便是使用厚样品和大尺寸样品，研究人员也能够快速轻松地准确观察和分析生物学过程和结构。然而，离焦荧光会提高背景荧光，降低对比度，影响图像的精确分割。THUNDER 与Aivia 的组合可以有效解决这一问题。前者可以消除图像模糊，后者会使用人工智能技术自动分析宽视野图像，提高操作速度和精确性。下面，我们来详细了解下这一协作方法。

Save Time and Effort with AI-assisted Fluorescence Image Analysis

The powerful synergy of THUNDER and Aivia analyze fluorescence images with greater accuracy, even when using low light excitation.
