为活细胞成像创造新选择

对厚实的活体样本进行成像时，主要挑战之一是获得图像质量与组织完整性之间的平衡。长时间的图像采集期间，弱信号光会导致低信号水平，导致图像对比度低以及分割和分析困难。需要通过高剂量成像或高时间分辨率成像技术加强信号强度时，这一问题更加突出。一个常见问题是：我如果快速成像、一次完成，会不会造成样本过度漂白或者细胞死亡？

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。
