CT Atrophy Batch processing dialog: fixed uninitialize memory error in # of slices required.
CT Atrophy Batch processing dialog:  added the checkbox option for the "Include Multislice Volumes only with at least N slices".

Friday, February 6, 2015

Fixed the DICOM loading error (IMAGE_POSITION incorrect).
Implemented more robust parallelization scheme for DICOM load.

FireVoxel Build 172 is released.
CT Brain atrophy batch processing: fixed several defects including "missing TAG", "present MR modality", "ROI is empty" problems.  Increased default minimum number of slices to 20.

EdgeWave functions and the Dialog box have a new option to process in 2D mode (i.e. slice by slice)
Variant of processing on "pseudo-Huang"
Additional steps:
1.  Image is smoothed with Median filter Rad=2
2. EdgeWave is applied in 2D mode.

Note that results on lower (closer to neck) slices would not be reliable.

HYDROCEPHALUS study: an attempt to use the sulcal depth histogram

CASE A:  projections




CASE A- Sulcal depth map and distribution (notice average\median depth of  300\211 in 0.01 mm)

CASE B: projections
CASE B:  sulcal depth average\median = 187\134  (in 0.01mm units)

Open DICOM dialog: corrected the behavior of the "Refresh" button.
CT Atrophy batch processing:  Remove Temporary (File reference) Folder after the execution.
FireVoxel Build 170 is released.
Dialog 'ROI Split by threshold" : Corrected the "Initial value uninitialized" defect.
CT Brain Atrophy Batch workflow:  fixed the ROI threshold definition to match one provided by UI-level "ROI Split by threshold" function.

EdgeWave algorithm:  eliminated several major memory leaks
DICOM load:  enabled loading of DICOM volumes NOT containing the TAG_IMAGE_POSITION and\or  TAG_IMAGE_ORIENTATION.
