Once we have an FBP algorithm, there should be no problem at all to obtain a convolution backprojection algorithm. All we have to do is to take the inverse Fourier transform of the weighted ramp filter to get a convolution kernel. This is easier said than done. The problem is that we have a closed-form expression ... shoe store magnolia street fort worth https://bulkfoodinvesting.com
