The histogram image, when saved in Dicom format, is saved as an RGB image. A Study/Series UID translation table is kept while the program is running for repeated processing (Repeat or manual). The image/file description in now taken from the Derivation Description (replaces Series Description), except for Spectroscopy images. Also, if no Derivation Description is present or is blank, the Series Description will still be used. The Derivation Description has been added to the Dicom Header dialog. The Batch Analyze processing in the Substance dialog can now use the region of interest created during Susceptibility processing. A warning has been added for Dicom Image save to use 16-bit if sending images to other Dicom devices.

02/20/03
Dicom region of interest files can now be selected for filter processing. If the selected analysis uses the AIR software package, the program tests first before running and notifies the user if the package cannot be found.

02/19/03
The minimum report file for Iso-Data has been fixed for Dicom format files. Resources were added for Restoration, Registration, Segmentation, Substance, and Iso-Data. To initialize single-dimension arrays to 0, memset or calloc is used. The image sorting for Repeat is done by the repeat procedure, not by the user in the Image Load dialog, to force the images to be in the same order as the first set of images processed.
02/13/03
Automatically saved regions of interest and reports will be named correctly if Dicom is selected. Load Roi with Match Locations selected will load correctly. If using Dicom regions of interest in Substance, "voi" files can be found for use with Roi processing. The resources for the Load and Save dialogs are set at beginning of program, before they were not set until the dialog was brought up. The Region of Interest Clear button will only clear the drawn region of interest, not the region of interest being drawn to perform an erase (Erase-Irr).

11/15/2002
The shift image is correctly calculated, when a manual susceptibility correction is applied (switched sign). The current program settings can be saved using File->Save Settings from the Main window. Only those settings that have a corresponding resource can be saved (Load/Save, Region of Interest, Display, and Browser).
11/11/2002
In the Spectroscopy dialog, support was added for LX formats and non-square matrices. The Dump Display Buffer can be done for real or complex data. The user can select whether the data loaded is in time domain (normal) or frequency domain.

Subimage has been added to the spectroscopy dialog under Analyze. The susceptibility table can be restored from a shift image or a susceptibility file, a shift image will be created as needed. A single, grid, or stack plot can be done in the spectroscopy histogram. While the spectroscopy dialog is up, the graticule on the Display Image will show the spectra boundaries. Most of the region of interest functions now link properly for different size images, the exception is for region functions that specify size (rectangle using dimensions).
09/23/2002
Fixed the # images in the Display/Browser Window titles when the # of images changes. Use better error-checking for # of images in registration match functions. Save last Match (Registration) parameter file for use on another browser (lost when program is restarted).

The perfusion dialog was rearranged and Tmax definition added to clarify processing procedures for perfusion. A bug has been fixed where the program crashes when an HFH format image is read.
09/12/2002
The Start, Increment field in the Dicom Header dialog has been removed. The information can be put in the element field directly. Comma separated strings can be entered in the Dicom Header dialog element fields to put a different string in that field for each image header. The # Images is displayed in the Browser/Display window titles, after the Display/Browser #. In the Display Window, c key can be pressed to display the center image. The Repeat function has been fixed in the Perfusion dialog.

The keyboard can be used to change the displayed image in the Display Window. The Browser Window is resized correctly, when no scrollbar is present.
08/20/2002
The resize function for the browser window has been fixed, previously was using the previous size, not the new size. The filename list will not be visible behind the images for non-standard image sizes, e.g. 192 x 256.
08/15/2002
The Delete function will not delete patient series, if a filter is used in the Image Load or File Load dialog, but no images/files are selected. Only the images displayed will be deleted. If no images/files are selected and no filter is used, the entire patient series is deleted. Dicom format images can be uncompress and compressed. The Repeat function for restoration has been fixed to keep the user-supplied values.
08/06/2002

All histogram information is reset, when Cancel is selected in the Histogram Window. The most-likely used text field will be made the keyboard focus. The user selections in the Restoration Dialog are kept, even when the dialog is restarted. The X values (TE, TR, B, etc) are printed if the X function is changed.
08/5/2002
The scrollbars on the browsers are now linked, if selected. An option has been added to the browser to display the region (or volume) of interest on the browser images. The browser used in segmentation is not reset if the segmentation dialog is restarted. A bug where the histogram is incompletely destroyed has been fixed.
07/29/2002
Several bugs were fixed that caused repeat to crash after segmentation or substance processing. The substance map values are not printed for each location if in repeat mode or using the browser version. The legend colors now match the plot colors in the temporal histogram for more than 4 vectors.
07/25/2002
The description is added onto from the left, so most recent processing is visible in Image Load dialog.
07/23/2002
The temporal histogram performs better error-checking and messaging. The series description is kept in the description until description length exceeds maximum length. The Standard Iso-Data standard areas can be selected form iso-data clusters, displayed regions of interest, selected region of interest files, and/or selected signature files.
07/02/2002
The help page locations have been fixed for Iso-Data, K-Means and Fuzzy C-Means, Functional, and Perfusion. The Standard Deviation and Lumping Parameters calculated from regions of interest have been fixed (Roi and L Roi in Iso-Data dialog).

The values not in the slice ranges will be ignored when calculating the intensity plots. A bug in Standard Iso-Data processing has been fixed. The help pages are also incorrect, when selecting a Standard Region using a region of interest, a region of interest file must be selected in the File Load dialog. The displayed region of interest will not be used. This will be changed in the future to check for a displayed region of interest first. A crash when loading images with long HFH filenames has been fixed.
07/01/2002
Fixed bug in Pad (Math dialog) where not all images were allocated the correct region/volume of interest size. Fixed mutual information registration to work correctly (rotation was not correct when plotting intensities). The patient name is now split correctly into first and last for Dicom images saved within eigentool so that the Image Load dialog correctly displays the new information. The HFH directory name is now split into last_first_date_description. A bug overwriting other fields in the Image Load dialog has been fixed.
06/21/2002

04/24/2002
The Image list sorting can be disabled using a sort option in the Image Load dialog.
04/19/2002
