Images

The Images page allows the user to adjust image zoom factors, activate auto-orientation, and customize window/level settings.

The Images Settings contains a subset menu of four customization tabs:

Auto Orientation

Auto Orientation Settings Default Description
Left/Right Auto Orientation Left Automatically set the left or right side of axial images to the right edge of the image frame
Posterior/Anterior Auto Orientation for Sagittal and MG images Posterior When set, override the modality-defined orientation and set the posterior or anterior side of sagittal and mammography images to the right edge of the image frame
Posterior/Anterior Auto Orientation for Axial Images Anterior When set, override the modality-defined orientation and set the posterior or anterior side of axial images to the top edge of the image frame

See: Auto Orientation

Compression

Compression Settings Default Description
Compression Auto Algorithm used for compressing images
Wavelet Quality Lossless When using wavelet compression, use bit conserving quality factor (Lossless) or terminate the decompression when the selected ratio (N:1) is achieved

Window and Level

Window and Level Settings Default modality Description
Apply VOI LUT Enabled Apply the VOI LUT, if present, to the image when displayed
Minimum of W/L range 0 Set lower boundary for window/level
Maximum of W/L range 4096 Set upper boundary for window/level
Default W/L preset Initial The default window/level preset applied to images when loaded into an image frame
Automatic W/L range (in %) 95 Reduce the data set to the defined distribution range
Aggressive Disabled When enabled, the window and level values calculated from the data distribution reduce high occurrences of background noise
Auto W/L setting No override Override predefined window and level settings using the internal analysis program
Unify W/L settings Disabled Override the explicit W/L value for each object in the series for a single calculated value

Note:  These settings are modality specific.

Window and Level

Zoom

Zoom Settings Default Description
Zoom Mode Fit to window Set zoom mode
Enhanced Smart Fit Disabled Attempts to identify anatomy that is not breast
Enhanced SmartFit Detection Disabled Updated algorithm that increases the success rate of skin line detection.
Magic Zoom Factor 3000 Defines the magnification applied to the data inside the magic glass window

Default Snap Zoom Factor 1000 Set the magnification applied to the image after invoking any of the snap-to-functions

See: Magnifying the Image

Image Snapping

Image snapping settings Default Description
Default snap zoom factor 1.000 Set the magnification applied to the image after invoking any of the snap-to functions

Pixel spacing

Pixel spacing settings Default Description
Use Estimated Radiographic Magnification Factor Enabled Use Estimates Radiographic Magnification Factor for correct Pixel Spacing values.  If this DICOM value is not available but Distance Source to Detector or Distance Source to Patient is available, then it will be used to correct pixel spacing.

Magic Glass

Magic Glass settings Default Description
Magic zoom factor 3.000 Defines the magnification applied to the data inside the magic glass window
Enhanced ROI zoom factor 3.000 Defines the magnification applied to the enhanced ROI window

Mammography view

Mammography view settings Default Description
Enhanced Smart fit Disabled Enhances the Smart fit zoom applied to breast anatomy by excluding non breast anatomy below and above the breast
Enhanced Smart fit detection Disabled Enhances the initial detection needed for Smart fit zoom and applies a new threshold algorithm for detecting breast anatomy

Progression

Progression Settings Default Description
Progression Overlapped (in %) 10 Percentage of theimage highlighted in the progression mode border
Auto progression size Disabled

Reverts back to the previous (auto-sized) progression step feature.

Horizontal progression tiles 1 Number of horizontal tiles applied during progression sweeps.
Vertical progression tiles 3 Number of vertical tiles applied during progression sweeps.
Show overlapped area Enabled Highlight regions that do not belong to the current progression area but are visible in the image view

Export

Export Settings Default Description
Show folder Disabled Automatically open folder containing newly saved images.
JPEG quality 100 Determines the quality of exported .jpg images.
TIFF compression scheme None Specifies the compression methos applied to .tig images.
