FireVoxel Build 268 is released.


1. Implemented a workflow for Kidney Segmentation from Arterial Phase v.2.  Only requires a bounding rectangle of kidney on a single slice.












2. Finalized the Texture Analysis Batch workflow, with numerous new options:  Histogram Range,  Exclude Outside Range,  Voxel Weight Type.

3.  Implemented a stand-alone function for Texture Gradient Single Scale.  Replace radio buttons with ComboBox element.

4.  In Kidney Segmentation Workflow, the Kidney Patient side is automatically detected and the corresponding layer name is modified. 

FireVoxel  Kidney DCE segmentation workflow from a single Arterial Phase image:

FireVoxel  Build 267 is released.

1.  Texture Analysis dialog:  added parameters  Histogram {NumBin,RangeMin,RangeMax}

2.  Volume Projection settings:  implemented a new option "One Slice base only".  This is a regular projection but only the Base Layer is displayed.

3.  MainMenu>View>New View   :  corrected the defect so all the views are Re-tiled in this operation.

4.  Enabled the MultiView synchronized scroll.

5.  Output header at the top of the  Texture Analysis Log file.

Source folder = E:\000000_TestTexture

Texture radii (mm) = 0,2

Outer layer width (mm) = 3.000000

Inner layer width (mm) = 2.000000

Num inner layers       = 2

Hist num bins          = 100

Hist range min         = 0.000000

Hist range max         = 100000.000000

FireVoxel Build 266 is released.


1.  Fixed defect in Applications>Brain MR>Automatic seed finder when the slice index was changed to a random value after the operation.

2.  Implemented a general operation for all models, so that the Input Function can have entirely different timing from the TAC data.  Integrated with model #32:  FDG 2 compartment Model

FDG 2CM data obtained as TAC (*.txt) from Jean

3. Fixed redundant sorting problem when constructing the DICOM tree (observed on Renal data)

4. Added and ABT unit subtest for the Model 32:  "FDG 2CM"

FireVoxel Build 265 is released.

1.  All EdgeWave-related processing was upgraded to seeds with double float coordinates.

2.  Changed the notion of a single slice VROI so the [Z0,Z1] coordinates are now [z,z+0.99....]

3.  Kidney Segmentation from Arterial Phase (KSFAP):  implemented a single click workflow with the dedicated dialog box.









4.  Produced an initial documentation "KSFAP QuickStart"

5.  Modified the "Save Stats"  file procedure in the RoiStats3D dialog box.

Implemented an Automatic  keypoint generator for the deformable registration based on the Texture Edge detector.  It provides results visually comparable to the Foerstner Keypoint detector, so it can become a viable alternative to Foerstner.
Advantage is that it is more studied and optimized in FireVoxel.  Eventually quality of the deformable registration would be compared for two or more keypoint algorithms.

Foerstner - Green squares, URAL texture is red dots.

   

Updated parameters for AutoMatic Kidney segmentation to improve segmentation results:

case Good1  Ctx+Mdl = Whole Kidney masks

Following parameters were changed:
In the first EdgeWave step , the Peel was reduced to 1 mm.



Also insured the Kidney is clipped 2nd time after the Whole Kidney mask is obtained








In the last step of (Bright Ridge Segmentation), the threshold parameter was reduced.
