FireVoxel Build 353 is released.

 

 1. Cardiac Output dialog parameters are now remembered between dialog restarts.

2. Made correction to the Gamma Variate fit and added the Wait Cursor.

3. AutoFocus registration:  when the single Affine Grid transformation is considered(Translation only) then the progress bar is displayed.

4.  AutoFocus final transform: fixed defect when ROI layer is tranformed the Empty color (VOIDVOX32) was incorrect and causing the empty fields getting value 1.

5. Implemented a specialized function to Uncrop kidney volume to the original FOV including ROIs.

         a) Load both Cropped and FFOV documents. 
         b) In FFOV documents unmark all the layers except for the main (base) layer.
         c) In Cropped document unmark all the layers except for the main (base) layer and one significant               non-empty ROI (as in screenshot). 
         d) Make the Cropped document active.
         e) Go to MainMenu>Workflow>CERENE3D>Uncrop Volume command.
         f) Dialog box will appear with all parameters set.  The only parameter that might need changing                  in the future is the Translation X,Y,Z. Default 100mm was sufficient for this example.
         g) Press OK. After some processing all the Layers of Cropped document will be transferred to the             FFOV document.
        h) Result:


 

6. Updated the Cardiac Output-based Input function correction functionality. Added the Gamma Variate fit parameter












7.  When DICOM is loaded with trivial Slope\Intercept (1\0) verification dialog does not appear anymore.

FireVoxel Build 352 is released.

 

 1. Concentration conversion dialog : Updated the parameters in the Signal Baseline panel. Items are grayed if Manual parameter not checked.

2. Gamma variate fit upgrade: provided algorithm improvement to deal when signal starts after long delay.

This works in conjunction with Concentration conversion:

In HUANK case:

User specifies the initial phase:





Gamma variate fit is properly done by skipping specified points and looking for the optimal X0 now.





3.  Gamma Variate curve is now drawn with 0.1 sec steps for more intuitive viewing. Point markers are still shown in original time.





4. Cardiac Output correction dialog box:  when the curve is not loaded all the appropriate UI documents are grayed.

5. Cardiac Output dialog \ Attributes \  opened dialog now titled Blood attributes.

Build 351A is released.

 1. White Matter lesions detection: provided algorithm update for morhological closure of Brain Mask Base. Provided UI dialog field for updating the closure value in mm.

2. RoiStats3D dialog box: when only ROI layer is present the voxel and blob count is now calculated correctly.

3. IDIF function : fixed defect when Isotropic volumes are not processed.

Build 351 is released.

 1. Implemented initial variant of UI function:  DICOM Tree to Folders.

2. Fixed crash defect in RoiStats3D dialog:  when invoking the Zigalga-threshold. 

3. DICOM Tree to File Folders:  added handlers to when Source and Target folders do not exist,

when size of the free space in the Target folder is not sufficient.
