Build 356 is released.

 1. MainMenu>File  :  implemented an additional function for loading DICOM files as SERIES, without constructing logical Volumes.

2. CO measurement and Correction tool : made available from the main menu under Dynamic Analysis

 

3. File>DICOM>Save Volume to Folders  option saves into the specified Folder but the files are sorted into subfolders by their respective SERIES.

4.  When DICOM Loading in "All checked items" mode additional checks for compatibility with the Volume such as {Orientation,  Slice Location} etc.

5. When Invalid FVX file contains DICOM header size=0, an appropriate diagnostics is displayed and the function orderly exits without crashing.

6.  Models {19,21,28}:   removed the Noise and RelPrecision parameters from the User Interface

7. Model {28} : Output Parameters and RMSE bounds after (global) optimization.

8. Enabled GO Solution Bounds in Monoexponential fitting.

Build 355C is released.

 1.  Save DICOM UI function (both the MainMenu>File and from LayerContol dialog) :  option pops up to generated all new random UIDs (SERIES, etc) or preserve the ones from original file.

2. DICOmM Deidentify function:   resulting files change the name to  image_XXX."original extension". Original files are deleted. Progress message now shows how many files are processed.

3.  Registration>Using Landmarks:   replaced the Affine Transform (which was previously done using Poly engine) with the explicit Affine optimization. 

Build 355B is released.

1. Made UI corrections in  Workflow>Rodent>Register to PET space.

2. CO correction tool:  fixed crash when no curve is loaded and user clicks on the plot area.

3. CO correction dialog : changed the dialog title. Removed the CLOSE (X) button which was causing the Stats notepad to show up and dialog would not close (Windows Bug?)

4.  MasterFilePresent checks avoids the expiration date check.  This allows to easily test old expired versions.

Build 355A is released.

 1. RoiStats3D dialog:  Histogram setting behavior change:

In Multilayer entity every layer volume (both Roi and Non-Roi) remember the range but keeps the track if ROI content is changed or the measure layer is different. Histogram parameters are now remembered within the ROI.

2.  FullRange button is enable only if the current range is not a FullRange.

Build 355 is released.
 

 

 1.  DICOM Tree to File Folders tool:  implemented the proper naming of Patient\Study\Series folders.

2. Verified correctness of the operation:   Load DICOM -> Save NIFTI ->Reload in the 3rd party package and display orientation correctly.  Checked out :  3D Slicer, MRIcron, ITK-SNAP all working correctly. Mango does not.

3. NIFTI load orientation:  added code for when sform>0 and qform=0. This fixes the NIFTI nih test dataset problem.

 

 

 

 

 

 

4. User Interface options dialog:

Corrected the "Posterior on Top" to "Anterior On Top"

 

 

 

5. Fixed PET-4D Dicom Load defect (mouse volumes with Non-isotropic pixel).

7. WML lesion processing:  both Base2016 and V353 versions are exposed on the corresponding menu now. 

8. Fixed: When Layer Dialog box was open, after the parametric model ran it was not updated completely.  Presently, if "Process ROI only" mode isactivated the ROI is automatically disabled at the end so we can see the ParametricMap clearly. So Auto disable was not reflected in Layer Dialog.

 

9.  Model 29 (MRTM0):  changed the definition of   R₁ = −β₂/β₃.  to match the definition in Ichise paper here:  

https://journals.sagepub.com/doi/10.1097/01.WCB.0000085441.37552.CA?url_ver=Z39.88-2003&rfr_id=ori%3Arid%3Acrossref.org&rfr_dat=cr_pub++0pubmed&

Build 353 is released.

 

 1. Cardiac Output correction dialog:  added the optional display of the First Pass Curve used for calculation of the AUC in CO.

2.Modified first pass curve so the starting segment before the first non-zero concentration is interpolated by gamma variate.

3. Provided a new variant of the Gamma variate fit which guarantees that the peak of GV exactly matches the peak of the original curve.

 4. Implemented Concentration->Signal conversion for T1WR1NLC concentration method. This is required.

 5. DICOM load: enabled loading of the DICOMs with 32-bit signed\unsigned internal representation. 

6. Cardiac Output Calculation and Correction dialog:

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
