ScanIP™ Technical Data

• Image Processing Software ScanIP
• Import formats
• User Interface
• Image Processing Tools

ScanIP offers an intuitive and interactive environment to assist the user in segmenting 3D data into one or more masks.

• 3D Formats - DICOM version 3.0 (including various encodings of JPEG, RLE), ACR-NEMA versions 1 and 2, Interfile, Analyze, Meta-Image, raw image data.
• Stack of 2D images - 2D DICOM, BMP,GIF, IFF, JPEG, PCX, PNG, PNM, TIFF, XPM.
• Raw image import

The ScanIP user interface consists of a range of user definable dockable windows. Multiple projects/3D datasets can be opened simultaneously. Multiple undo and redo of commands is also provided.

• 2D/3D viewing - up to three 2D views and one 3D rendered view (employing Level of Detail (LOD) surface rendering) can be used to view greyscale and mask data. The coloured masks can be shown as either translucent (intensity reflecting underlying greyscale) or solid.
• Slice Browser - will display 2D slices in any one of the three native coordinate directions as selected by the user. Active masks are shown overlayed on greyscale data and the slice browser can be used to select a range or subset of slices to work on.
• Tool Selector - enables users to input required tool parameters.
• Mask Browser - provides a range of functionalities for manipulating masks.
• Histogram and Profile Line Utilities - assist in finding the best threshold values.
• Ability to handle Multiple backgrounds - brings more flexibility to the segmentation process.

• Data Processing - crop, pad, rescale, shrinkwrap, resampling (also sometimes called re-slicing), flip.
• Noise Reduction/Smoothing Filters - recursive Gaussian, gradient anisotropic diffusion, curvature anisotropic diffusion, curvature flow, min/max curvature flow, bi-lateral filtering.
• Morphological Filters - erode, dilate, open, close (on both greyscale data and binary masks).
• Level Set Methods - allow segmentation based on implicit surfaces. Contour specific features (e.g. curvature) can therefore be controlled during the region growing/surface adjusting process.

The following operations can be applied to the whole volume or to a subset of slices (as selected interactively from the slice browser).

• Paint/Unpaint - user definable brush size.
• Confidence Connected Region Growing - iterative merging based on statistical similarity constraints.
• Flood Fill - region growing, either based on threshold bounds or delta change in greyscale. This can be applied to greyscale or mask data (cavity fill).
• Thresholding - from tool selector menu or can be launched from histogram and profile line utilities.
• Boolean Operations - union, intersection, subtraction, invert (applied to/between masks).
• Overlap Check - display/generate mask to check overlap volume in active masks.
