spa2pro 2.0.0 © 2003-2005 by Turku PET Centre

For program testing and simulation. Transforms the given image in spatial domain to a sinogram in Radon domain. Uses the tranformation functions in the reconstruction utilities library libtpcrec. Usage: spa2pro [Options and Arguments] <Image> <Sinogram> Options: 1) Discretization model; default 0/1 model. -m<0[,s] (0/1, with s sublors if given) 1[,s] (length of intersection, with s sublors if given) 2 (exact area) 3 (linear interpolation) 4 (nearest neighbour)> 2) Fit input image to [-1,1]x[-1,1]. -f 3) Run in noisy verbose mode. -n 4) Print build information and exit. -v -V Arguments: 1) View number; by default determined from the input image. -a<number> 2) Bin number; by default determined from the input image. For methods 3 and 4 bin number must divide the image dimension. -b<number> Input files: 1) Image: image volume in ECAT or Interfile format. Image format is determined from the file name extension; ECAT = .v and .img Interfile = .i (+.i.hdr) 2) Sinogram: sinogram in ECAT or Interfile format. Sinogram format is decided from the file name extension; ECAT = .s, .S and .scn Interfile = .i Keywords: reconstruction, simulation, ECAT, interfile
