我们引入了一种概念,可以在各向同性300-350纳米分辨率的大体积中实现并行三维成像。通过在数字扫描光片荧光显微镜(LSFM)的聚焦深度内横向和轴向错开高纵横比照明光束,可以以最小的串扰和光损失同时对多个图像平面进行成像。我们提出了这个概念的并行成像的第一个演示,通过合成两个非线性贝塞尔光束的光片,并执行荧光珠和浸润性乳腺癌细胞的体积成像。这项工作表明,原则上,任何数字扫描的LSFM都可以以无损的方式并行化,从而在给定的样品亮度和检测器技术下实现更快的体积图像采集速率。
We introduce a concept that enables parallelized three-dimensional imaging throughout large volumes with isotropic 300–350 nm resolution. By staggering high aspect ratio illumination beams laterally and axially within the depth of focus of a digitally scanned light-sheet fluorescence microscope (LSFM), multiple image planes can be simultaneously imaged with minimal cross-talk and light loss. We present a first demonstration of this concept for parallelized imaging by synthesizing two light-sheets with nonlinear Bessel beams and perform volumetric imaging of fluorescent beads and invasive breast cancer cells. This work demonstrates that in principle any digitally scanned LSFM can be parallelized in a lossless manner, enabling drastically faster volumetric image acquisition rates for a given sample brightness and detector technology.
