This directory contains code for tomographic reconstruction. Uncompress files with 'gunzip filename.tar.gz' then untar with 'tar -xvf filename.tar' (Linux: use 'tar xvf filename.tar', w/o '-') Files in this directory: ------------------------ I. GENERAL PURPOSE CODE -------------------------------------------------------- MAP_ICD.tar.gz general purpose MAP-ICD for PET CBP_PU.tar.gz general purpose CBP with ramp and Hanning filter II. IU IndyPET SPECIFIC RECONSTRUCTION CODE -------------------------------------------------------- IUrecon.tar.gz Reconstruction code for the IndyPET scanner. This code performs MAP-ICD reconstruction using a GGMRF prior. Code is based on MAP_ICD but uses different file i/o (cti and matlab) and different tomographic projection matrix. IUcalib.tar.gz Code for estimation of empirical system kernel for IndyPET scanner based on scans of line source phantoms. The estimation itsself is in Matlab, but included in the package is a required version of IUrecon that is needed for the single-frame reconstructions. CBP_IU.tar.gz Convolution backprojection (CBP/FBP) code for the IndyPET scanner. This code is a little less user friendly, and is meant for research use. III. IU IndyPET PET DATA -------------------------------------------------------- barphtm_hc.tar.gz Bar phantom PET data collected on IndyPET and configuration files and command-lines for MAP reconstructions using IUrecon. brainphtm.tar.gz Brain phantom PET data collected on IndyPET and configuration file and command-line for MAP reconstructions using IUrecon. IV. ADDITIONAL FILES -------------------------------------------------------- Matlibs.tar.gz Matlab libraries for all architectures version 5.3.1-update. Will work with all code in this directory. This might be needed in case you don't have the matlab libs installed on your system or your admin decides to remove version 5 and go to version 6. This is part of the COPYRIGHTED Matlab distribution, it is NOT meant for general distribution.
