| Popis: | We present here a 3-D image processing applied to coded aperture imaging. As a code we use a ring, and decoding is performed by deconvolution. Depth and lateral resolution are examined by Fourier and object space analyses. In particular contrast inversions are put in evidence and their influence in nuclear medicine is discussed. The theory is confirmed first by computer simulations, then by “in vivo” images of the heart. |
