Description
technical field [0001] The invention belongs to the field of micro-CT systems, in particular to a micro-CT system based on p-type laser orthogonal two-dimensional discrete wavelet HARR function image analysis with simple structure and capable of improving the quality of diagonal pyramid three-dimensional tomographic image reconstruction and its Control Method. Background technique [0002] Currently, common CT imaging systems do not have the technology for micro-CT to increase the geometry of the homogeneous laser focus spot using p-type lasers in the visible (VIS) band. It does not have a two-step overlapping two-dimensional discrete HARR function wavelet transform image enhancement filter, but only performs a two-dimensional discrete HARR function wavelet transform image enhancement after the back projection (back projection) calculates the three-dimensional tomographic image f_i(x,y) filtering. The existing problem is that it is not conducive to capturing tiny image inf...
