生物显微镜图像模拟:微石

Image simulation for biological microscopy: microlith

Shalin B. Mehta, Rudolf Oldenbourg

摘要:

图像模拟仍然是开发最广泛使用的生物相位显微镜方法,因为在模拟部分相干照明的困难。我们描述了一个开源的工具箱,microlith(https://code.google.com/p/microlith),它准确地预测与任何部分相干成像系统,包括相干照明和非相干,自发光的标本观察到的薄标本的三维图像。它的准确性证明了模拟和实验的明场和暗场图像的特征以及振幅和相位的目标,分别。比较提供了新的见解的暗场显微镜的灵敏度在孤立的或周期性的标本在10 nm的长度尺度的质量分布。基于使用microlith预测,我们提出了一种新的方法,用于检测纳米级的结构变化,在跳动的轴丝使用暗场显微镜。

英文摘要:

Image simulation remains under-exploited for the most widely used biological phase microscopy methods, because of difficulties in simulating partially coherent illumination. We describe an open-source toolbox, microlith (https://code.google.com/p/microlith), which accurately predicts three-dimensional images of a thin specimen observed with any partially coherent imaging system, including coherently illuminated and incoherent, self-luminous specimens. Its accuracy is demonstrated by comparing simulated and experimental bright-field and dark-field images of well-characterized amplitude and phase targets, respectively. The comparison provides new insights about the sensitivity of the dark-field microscope to mass distributions in isolated or periodic specimens at the length-scale of 10nm. Based on predictions using microlith, we propose a novel approach for detecting nanoscale structural changes in a beating axoneme using a dark-field microscope.
