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