Is there any way in matlab to reconstruct an image from 1D data set which represent projections from 0 to 180 degrees rotation other than iradon as iradon seems not to work. Sign in to comment. Web5 sep. 2024 · For example, to reconstruct a 200 × 430 × 200 matrix, it takes half an hour on GPU-based MATLAB on our PC with an NVIDIA Titan X, using the focal-line-based 3D reconstruction algorithm . Even with the fact that MATLAB is not time-efficient, this processing time is still considerable, placing a burden on the “pipeline” of 3D PA studies.
