1 Version 3.5 New Features
3 * New reconstruction method: Direct Fourier!
5 * Multithreading for running length processes in background. Also
6 takes advantage of multiple-CPU's in SMP systems for speed improvements
7 with parallel processing.
9 * Interpolate divergent beams to parallel beams for faster reconstructions.
11 * Region of interest can be specified for reconstruction zooming.
13 * Import PNG, PPM, and PGM images
15 * DICOM file import/export
17 * Clipboard for cutting and pasting images
19 * Can read and reconstruct SIEMENS AR.STAR DICOM raw data files
21 * Scattergram of T-Theta sampling. Useful for understand divergent beam
24 * Startup-tips to help new users learn features.
26 * Ability to place detector at any arbitray position
28 * Histogram plotting of projection files
31 Version 3.0 New Features
33 * Greatly improved dialog boxes
35 * Online and print manuals with context-sensitive help!
37 * 3-d rotating views of image files
39 * Creation of arbitrary filter images
41 * Cubic interpolation for reconstructions
43 * All features of command line tools are now in graphical ctsim program!
45 * Complex-valued image files now supported, lots of image math
46 functions added including Fourier transformations
48 * Visual and statistical image comparision functions
50 * Plotting of row and column data of single and comparison images
52 * Histogram Plotting of Image files.
54 * Conversion of projections to polar images
56 * Improved animation graphics
58 * New Microsoft Windows compatible self-installer with explorer extensions
63 Version 2.5 of CTSim has been released!
65 New Features of CTSim version 2.5:
67 - Now compiles with Microsoft Visual C++.
69 - First Microsoft Windows graphical user interface
71 - Bug fixes and modest documentation and program improvements over version 2.0
75 New Features of CTSim version 2.0:
77 - Entire code-base cleaned up, re-written, and converted from C to C++.
79 - Graphical user interface now included! Animation of projection and
80 reconstruction processes. Displays projection and image files. Uses
81 platform-independent wxWindows library so can run on UNIX and
82 Microsoft Windows platforms.
84 - Integrated G2 library for graphical display from command line tools
87 - Added frequency-based filtering. Can provide significant speed-up
88 in reconstructions compared to convolution-based filtering.
90 - Added highly-optimized backprojection method (idiff3)
92 - New command-line tools added for image statistics and comparisons with
93 both text and graphical outputs.
