Substantial MapFit algorithm improvement:  during the iteration of contour adjustment, the individual point replacement was calculated as "winner-takes-all" from competing displacements.
Now optionally there is an AdaptiveDisplacement mode. F.e. when several displacements have very similar scores ("unsure" situation)  the proposed displacement is normalized by the level of the confidence of the winning displacement.

Global Optimization on binary sets:  improved the speed by x3 due to algorithmic improvements.

Signal truncation in Pulsatility study:

Signal in certain areas with high signal is always truncated by 4095 (=12 bit).  This includes some blood vessels. Is this expected?

F.e. majority of the voxels in the Blue ROI (pictured) have a constant Signal=4095 through entire timespan.

FireVoxel Build 231A is released.

Implemented a Multiple-Selection capability inside the DICOM Browser dialog box.
Note:  Selection in this dialog is done by checking the items, not just highlighting them.
CTRL and SHIFT buttons are working.  Items could selected by holding {CTRL,SHIFT} be either
a) clicked by mouse :  CTRL=flip check state,  SHIFT = check state on
b) using Up\Down keyboard key  : SHIFT = check state on.  CTRL is not allowed.

Completely re-engineered parsing of the DICOM series to extract logically connected volumes.
There will be no more "Inconsistent DiCOM files" messages.

DICOM Dialog box:  fixed the Copy function when Image Nodes are selected.  It was not copied before when individual image nodes were checked, but worked for the entire series only.

CW Segmentation, Initial Seed function:  separated into standalone procedure.

CW Chestwall Initial Seed:  Two point segment algorithm:  latest result.

Algorithm notes:

Two stage algorithm:

A.  Non-Incremental evolution.

P.AgentSimilarGrad = false;

P.AgentSimilarSigntr = false;

P.AgentMaxGrad = false;

P.AgentGradContourNormal = true;

P.AgentSimilarGradDir = false;

P.AgentWholeContourSigSimilar = false;

P.AgentMaxEdge = false;

P.AgentSimilarHistSigntr = false;

P.AgentRidgeMap = false;

P.AgentPreferDark = false;

P.CandLogic = VA_CANDLOGIC_BEST_OF_SOFTMAX;

//P.CandLogic = VA_CANDLOGIC_AVERAGE_OF_BEST;

//P.CandLogic = VA_CANDLOGIC_AVERAGE_OF_SOFTMAX;

P.SnapEndsToSides = false; 

P.Subpix = 2;

P.IncEvol = false;

P.MaxNumIter = 1;

P.GradEdgeYneg = true;

B. Same as above, but

P.IncEvol =  true;

P.MaxNumIter = 20;

Chestwall Initial Seed automatic with 2 - User specified points:

Better result, but not a sure thing at all.  Obtained with 2 very different Evolution Radius parameters

MapFit Chestwall Initial Seed:

2-Agent design with AVERAGE_OF_BEST integrator (not SoftMax)

MapFit code:  parallelized code segment that calculates the SoftMax scores for displacement candidates.

Mid-Sagittal  Chestwall Initial Contour Seed:
Very first run using a 2 point segment specified for the user.  This is far from Final.

Displacement Field Smoothing and   Object Boundary Smoothing:
a) Unified the code to use the same function
b) Completely parallelized the code.

Contour smoothing procedure:  introduced a notion of Tension to reduce the appearance of Attractors in the contours when multitude of point tends to congregate in a small space.

Left:  New procedure     Right:  Old procedure with the attractor (red arrow)

Same as above figure, Zoomed In

Chest Wall segmentation:
While cropping the section of the chest to process User is aiding the segmentation at the same time.
Instead of drawing the box User chooses a line segment that specifies the cropping area.  In addition User asked that the segment starts and ends on the Chest Wall boundary as close as possible.
This would help tremendously with the Initial Seed during the MapFit procedure.

Corrected a bug in integrated Chest Wall segmentation function, when AirMask was produced as always empty, thus providing no constraints to the procedure.

Whole Breast segmentation using MapFit:  while EdgeWave seems to be promising on some examples, there are numerous extra challenging situations were EdgeWave would not work

out by itself.

FireVoxel Build 230 is released.

Kidney GFR   JZ3C model:   expanded parameter range from 40 to 80.
