Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0024] The present invention provides an optical projection tomography method based on a spliced helical scan mode. The method performs three-dimensional tomographic imaging on a plurality of local spiral projection data collected by an optical projection tomography system in a spliced helical scan mode.
[0025] Such as Figure 1a As shown, the current optical projection tomography generally adopts a circular orbit scanning method, and its effective imaging field of view is a cube. For large-sized samples, if the sample is forced to be completely in the cubic field of view during optical projection tomography scanning, the sample must be There will be a loss of spatial resolution. Such as Figure 1b As shown, the em...
