Emory Cardiac Toolbox™ Changelog

May 20, 2012¶

• Add support for Prone/Supine studies.
  • Add support for displaying orientation labels on the slices page (fulfills the new ACR 2012 labeling requirement).
• Add support for using custom display labels for Stress/Rest and Stress AC/Rest AC.
• Add Rest Total Severity Score, Reversibility Total Severity Score, and Stress/Rest/FDG-specific functional tags to the XML report file.
• Add a preference for whether or not to use hardware rendering for the Summary Page, PerfSPECTive Page, Gated 3D Page and 3D Cine on the Functional Page; this seems to help with the random issue of fonts showing up as solid blocks.
• Disable the slices cine start button when viewing AC data on the Slices page.
• Toolbox would crash if the additional Live directory did not exist at the time Toolbox tried to write to it (this usually happened when the additional Live directory was a network drive and it was unavailable).
• Add additional sanity checking to the DICOM date parsing routines (check to see if the date contains a "/"; none of the DICOM date VR's allow for a "/").
• SyncTool™ was incorrectly displaying the heart rate as 0 for rest-only or stress-only studies.
• Toolbox would crash when attempting to display the Parameters on the Active Viewbox page.
• If a user went to the SSS page, then to the Params page and changed something (i.e. the apex, base or center), then went back to the SSS page, the scores were not being re-calculated.
• If a user visited the Viability page, then went to the Summary page and exported the XML report, the quantitative information in the XML report (extent, defect mass, ...) would be from the Viability processing and not the Extent/Mass processing.
• Toolbox would crash when attempting to display the PerfSPECTive page on the Active Viewbox page, if the new hardware rendering keyword was set.
• Toolbox would crash if both a stress and rest gated dataset were available AND only one AC or one Prone dataset were available AND the AC or Prone data was displayed on the Slices page AND the gated cines were started.
  

January 24, 2011¶

• Add support for Vista and Windows 7.
• Add support for storing both Stress and Rest functional parameters in the XML report file.
• Add additional information to the XML report file (match/mismatch, injected dose, coronary ratios and phase) and change the XML encoding type to WINDOWS-1252 to be able to handle special characters (accents, …).
• Add support for using Dicom rescale slope and rescale intercept (as well as Xeleris scaling factors) to scale SPECT data (the dicom slope and intercept were already being used for PET data).
• Add support for scaling the Stress & Rest Polar maps to the injected dose and calculating coronary territory ratios.
• Add support for remembering the last path a file was saved to, when creating multiple screen captures, movie captures, ...
• Add support for creating Dicom Multi-Frame Secondary Capture (MFSC) images.
• Add support to preferentially select Motion Corrected data, if it is present.
• Update error handling to provide a better description of where errors occur.
  

• Review files viewed with ECTb viewers mistakenly were not enabling the PerfSPECTive and GQC licenses.
• The color table list was being displayed off-screen on monitors whose resolution was set to 1024x600 or smaller.
  

July 2, 2009¶

• Language localized GUI to: Danish, Dutch, French, Italian, German, Norwegian, Spanish and Swedish.
• Add a preference for setting the default screen capture type.
  

• Updated Dicom reading code to ignore ICON image sequences and header values.
• HeartFusion bug fixes.
• If a user went to the Extent/Mass page, the SSS page or the Viability page from the Study Verify Page (in processing mode), ECToolbox would crash.
• PerfSPECTive™ Artery options were changed to match those on the HeartFusion™ page.
• PET Review files from a Siemens e.soft (or Leonardo) that used the new Rb-82 CTAC Normal File (or Rb-82 CTAC/FDG Normal File) opened with the slices reversed.
• Fixed normalization issues when normalizing to the hottest pixel.
• Fixed potential round-off error in writing the end-systolic volume and the stroke volume to the XML report file.
• The gated mass is now being calculated using uninterpolated volumes.
• Fixed a problem displaying the endocardial and epicardial boundaries on the Slices page for gated studies with more than 32 slices.
• Fixed a display-issue when the counts of the rotating planar projection images were low.
  

August 6, 2008¶

• Availability of SyncTool™
• Add a preference for changing the Base Percent Threshold (the threshold used for determining the automatic base).
• Add an X scrollbar to the Functional Page, so the entire apical slice of the last frame can be visualized.
• Add the regression number to the EF displayed in the patient info area.
• Add the ability to save movies and screen captures for SyncTool™
  

• The patient name was being truncated to 31 characters in Dicom SC's
  

April 8, 2008¶

• Ability to show the normal file polar maps on their own page as well as the Active Viewbox page .
• Ability to display the endocardial and epicardial edges on the gated images on the Slices page.
• Ability to save a patient for use in creating a user-defined normal file.
• Ability to add user-defined normal files (up to 6) to the Toolbox.
• Ability to adjust AC and Non-AC parameters on the Parameters page.
• Ability to scale all images above 100%.
