Build 385B is released

 1. 4D-ROI Volumetric Measurement dialog box: fixed "Copy Curves" functionality to include the Time info and to open the Notepad.exe.

2.  Elongated object measurements:

a) Start-to-End distance in mm reported.
b) 4th column: for each point of centerline a sum of distance to Start and End.

3. Implemented UI function:   >Measure>Mutual Information between 2 layers

4. Curve analysis:  implemented a function to determine "Periodicity" of the curve. Integrated withing the lung workflow.

Build 385A is released.

 1. Remove the Test>ROI Longest Axis Centerline function from UI

2.  Workflow>Pancreas>Longest Axis:  text report now includes the name of the original document.

3. Lung Spirometry FEV1 : modified algorithm for noisy curve, so no negative values are allowed.

4. 2D Lung spitometry: modified curve analysis process so the peaks and bottoms are identical for L&R curves.

5.  Added ABT subtest for the FLEXR- MC Segmentation procedure.

Build 385 is released.

 1. Implemented prototype of Lung diaphragm movement detection and display.












2. Fixed the defect: Crop current timepoint in 4D volume was sometimes causing a crash.

3. Developed new segmentation algorithm for 4D Volume segmentation based on FLEXR-MC.  User draws organ ROI on the first timepoint and the procedure segments\registers that ROI on all remaining timepoints.

4. Fixed defects inside the FLEXR-2D algorithm.

5.Processed 8 patient cases for lung exam 2D+t, developed the Measurement reporting to characterize the lungs.


6. Defect fixed:  In ROI stats4D dialog when saving the TAC or copy clipboard, the signal value output was always positive (abs).

7. Defect fixed: when 4D volumes (without ROI) generates a parametric model in "As a single curve" mode, Report is pressed and the crash occured.

8.  Fixed situation: when NIFTI image file contained NAN FLOAT32 (not-a-number).  Such voxels are assigned 0 value instead so the loading could proceed.

 FireVoxel Build 384A is released.

1. Implemented new workflow item :

 MainMenu>Workflow>Pancreas>Measurement along Central Axis

2. For pancreas, the start of the axis is assigned to the End with the left-most coordinate. Provided an API for custom Axis Start logic.

3.  Axis measurement tool outputs text report that contains both the name of main layer volume and ROI.
