我们描述了一个OPT板执行光学投影断层扫描(OPT)的商业宽视场倒置显微镜,使用我们的开源硬件和软件的实施。OPT板包括用于对准的倾斜调整和用于样品旋转的步进电机,如标准投影断层扫描所需。根据放大率的要求,详细介绍了使用该转接板进行OPT的三种方法:传统的直接OPT方法,只需在物镜透镜后面增加一个限制孔径;外部光学中继方法,允许在放大率> 4倍的情况下进行传统的OPT;远程焦点扫描和感兴趣区域方法,用于提高空间分辨率OPT(高达~1.6 μm)。所有这三种方法都使用显微镜现有的非相干光源(即弧光灯),并且其所有固有功能都保持日常使用。在体内斑马鱼胚胎上进行OPT采集以证明实施方案的可行性。
We describe the implementation of an OPT plate to perform optical projection tomography (OPT) on a commercial wide-field inverted microscope, using our open-source hardware and software. The OPT plate includes a tilt adjustment for alignment and a stepper motor for sample rotation as required by standard projection tomography. Depending on magnification requirements, three methods of performing OPT are detailed using this adaptor plate: a conventional direct OPT method requiring only the addition of a limiting aperture behind the objective lens; an external optical-relay method allowing conventional OPT to be performed at magnifications >4x; a remote focal scanning and region-of-interest method for improved spatial resolution OPT (up to ~1.6 μm). All three methods use the microscope’s existing incoherent light source (i.e. arc-lamp) and all of its inherent functionality is maintained for day-to-day use. OPT acquisitions are performed on in vivo zebrafish embryos to demonstrate the implementations’ viability.
