September 18, 2020¶

• General improvements dealing with 3 or more gated series.

June 30, 2020¶

December 13, 2019¶

March 14, 2019¶

• Add code to cap stress extraction fraction corrected blood flow to 5x the extraction fraction corrected rest blood flow.
• Add Relative Flow Reserve to the FlowTool page.
• Account for frame reference time biases in dynamic data (ie initial time of frame 0 for dynamic data).
• Add setting to force SDS = SSS – SRS.
• Our current eccentricity values are really shape index values. So, add real eccentricity values and rename the current eccentricity values to shape index.
• Add real-time IDS sensitivity change option to Slices and Polar Maps pages.
• Add ENDG-necessary Base64-encoded arrays to the Legacy XML export. This allows the Legacy XML exports to be used to generate normal files.
• Check and make sure the max counts in the last frame of gated data are at least >10% of the max (ie, don't amplify noise).
• Connect the MouseWheel for Reference HLA slice selection (in addition to on-screen scroll bar) on the transaxial reorientation page.
• Tie ECTb window title text to visibility of Patient Info panel (F9 / view menu / setting) to resolve inconsistency of non-embedded presentations.
• Bug Fix: crashing on small hearts.
• Bug Fix: bounds checking on FindSAR.
• Bug Fix: Moving apex then base on gated params page could causes screen repaints to leave artifacts behind.
• Bug Fix: If default set to alternate view, and the alternate view does not have both stress & rest series, but the non-alternate view does have both stress & rest series, and we are loading a review file, then prevent Toolbox from crashing (getting a null exception).
• Bug Fix: Starting transmission or planar animations would enable the filtering drop-down that only has context for short axis.
