Embodiment Construction
[0020] 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. While illustrations of parameters including particular values may be provided herein, it should be understood that parameters need not be exactly equal to the corresponding values, but rather may approximate the values within acceptable error margins or design constraints.
[0021] The invention is an optical projection tomography method based on a helical scanning track. The invention is specially aimed at the projection data collected by an optical projection tomography system in a spiral orbit scanning mode, and performs three-dimensional tomography imaging to expand the imaging field of view. Such as Figure 1a As shown, the current optical projection tomography generally adopts a circular orbital scanning method, a...
