Local convolution in ectomography
In tomographic imaging, using limited angular sampling, details outside the imaged section are displaced along circles of blur. In ectomography, these are eliminated by a spatial convolution process. It is shown that the convolution function has to be as long as the projected dimension of the imaged...

Summary: | In tomographic imaging, using limited angular sampling, details outside the imaged section are displaced along circles of blur. In ectomography, these are eliminated by a spatial convolution process. It is shown that the convolution function has to be as long as the projected dimension of the imaged object perpendicular to the section and twice the dimension parallel to the section.< > |
