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 * Added startup-tips to help new users learn features.
24 * Added ability to place detector at any arbitray position
28 Version 3.0 New Features
30 * Greatly improved dialog boxes
32 * Online and print manuals with context-sensitive help!
34 * 3-d rotating views of image files
36 * Creation of arbitrary filter images
38 * Cubic interpolation for reconstructions
40 * All features of command line tools are now in graphical ctsim program!
42 * Complex-valued image files now supported, lots of image math
43 functions added including Fourier transformations
45 * Visual and statistical image comparision functions
47 * Plotting of row and column data of single and comparison images
51 * Conversion of projections to polar images
53 * Improved animation graphics
55 * New Microsoft Windows compatible self-installer with explorer extensions
60 Version 2.5 of CTSim has been released!
62 New Features of CTSim version 2.5:
64 - Now compiles with Microsoft Visual C++.
66 - First Microsoft Windows graphical user interface
68 - Bug fixes and modest documentation and program improvements over version 2.0
72 New Features of CTSim version 2.0:
74 - Entire code-base cleaned up, re-written, and converted from C to C++.
76 - Graphical user interface now included! Animation of projection and
77 reconstruction processes. Displays projection and image files. Uses
78 platform-independent wxWindows library so can run on UNIX and
79 Microsoft Windows platforms.
81 - Integrated G2 library for graphical display from command line tools
84 - Added frequency-based filtering. Can provide significant speed-up
85 in reconstructions compared to convolution-based filtering.
87 - Added highly-optimized backprojection method (idiff3)
89 - New command-line tools added for image statistics and comparisons with
90 both text and graphical outputs.
