-3.0.0beta1 - Released
+3.5.0 - Released 4//01
- * ctsim: Added accelerator (hotkeys) to windows
+ New Features:
- * ctsim: Online help added as well as HTML help
+ -- ctsim: Added direct Fourier reconstructions (Thanks to
+ Edgar Angeles for help with understanding FFT symmetry of
+ the projections)
- * ctsim: Added icons to Frames on Windows versions
+ -- ctsim: Added tips to be displayed at startup and via the help menu.
+ -- ctsim: Added center-detector concept. Allow for detector array
+ to be any arbitrary distance from center of scanner. As a result,
+ projection files are not incompatible with previous version of
+ CTSim.
+ -- ctsim: Added background and SMP processing for reconstructions,
+ scanning, and rasterization.
+ -- ctsim: Added generic threaded tasks and background manager for
+ background processing as well as taking advantage of multiple-CPU's
+ on SMP systems.
+ -- ctsim: Added plot t-theta sampling to projection file menu.
+ -- ctsim: Added Reconstruction with Rebinning for faster
+ divergent beam reconstructions.
+ -- ctsim: Added import and export of DICOM image files.
+ -- ctsim: Added PPM, PGM, and PNG file import to imagefile.
+ -- ctsim: Added FFT/IFFT of columns of image files.
+ -- ctsim: Added clipboard cut/copy/paste for image files.
+ -- ctsim: Added region of interest to reconstructions.
+ -- ctsim: Added Convert Rectangular Image to Projection files
+ -- ctsim: Added "Verbose Logging", "Startup Tips", and
+ "Background processes" options to Preferences dialog.
+ -- ctsim: Added plotting of projection file histograms.
+ -- plotfile: Added scattergram plot functions
+ -- ctsim: Added accelerator key for File-Properties
+ -- ctsim: Improved wireframe 3-d display to remove hidden
+ surfaces.
+ -- views.cpp: Added out of memory checks to display for huge
+ image and projection files.
+ -- backprojectors.cpp: Added setting of axis extent and increment
+ to reconstructions.
+
+ Bug Fixes:
+ -- filter.cpp: Fixed Hanning parameter to be 0.5 rather than 0.54
+ -- imagefile.cpp: Fixed scaling factor in fftRows
+ -- imagefile.cpp: Fixed bug when performing magnitude() on real-valued
+ image.
+ -- sgp.cpp: Fixed bug in drawCircle.
+ -- distribution: fixed problem with documentation files not
+ being included with the distribution [Reported by Ian Kay].
+ -- sgp.cpp/ezplot.cpp: Improved plotting with markers.

+
+3.0.1 - Released 2/19/01
