Description

Panel

Settings for:

 

The modality settings on this page apply to. Select Default to set the default settings for all the undefined parameters.

Apply VOI LUT

Enabled

When checked, apply the VOI LUT, if present, to the image when displayed. Default is checked.

Magic glass zoom factor

3:1

Defines the magnification applied to the data inside the magic glass window. The default is a 3x magnification.

Enhanced ROI zoom factor

1:1

Defines the magnification applied to the enhanced ROI window.

Default snap zoom factor

1:1

If the frame’s effective magnification setting is fit-to-window, this defines the magnification applied to the image after invoking any of the snap-to functions. If the frame’s effective magnification setting is not fit-to-window, the current setting is applied.

Progression overlap

10

Percentage of the image highlighted in the progression mode border.

Auto Orientation

L/R

Disabled

When checked, the selected patient position (Left, Right) of axial images is displayed on the right edge of the image frame.

P/A

Disabled

When checked, the selected patient position (Posterior, Anterior) of sagittal images is displayed on the right edge of the image frame.

Use W/L Range

Min

0

When overriding the defined window/level setting for an image, this is the lower window width setting. Total range cannot exceed 32K.

Max

4096

When overriding the defined window/level setting for an image, this is the upper window width setting. Total range cannot exceed 32K.

Automatic

Enabled

When enabled, use the actual pixel range as the window width and automatically calculate the level. When disabled, use the values defined in Min and Max. This setting applies only when no default window width and center value exists in the image object.

Interpolation

Use default

Enabled

Use the default interpolation algorithm.

Nearest pixel

 

Use pixel replication to create pixels.

Bilinear

Default

Use a bilinear interpolation algorithm to create pixels.

Compression

Use default

Enabled

Use the default compression algorithm.

Uncompressed

 

Do not use any compression on the image data.

Wavelet

 

Compress the image data using a progressive wavelet algorithm.

Auto

Default

The viewer selects the best compression setting based on network configuration and utilization.

Auto W/L Setting

Use default

Enabled

Use the default auto W/L override setting.

No override

Default

Do not override the W/L setting defined in the image object.

Override by study

 

When the entire study defines a full window width, replace it in each image with a calculated histogram equalization value.

Override by series

 

When the entire series defines a full window width, replace it in each image with a calculated histogram equalization value.

Override by image

 

When the image is defined with full window width, replace it with a calculated histogram equalization value.

Override all

 

Replace the W/L values for each image in the study with its auto range value, regardless of the default values.

Unify W/L Settings

Disabled

Override the explicit W/L value for each object in the series for a single calculated value when loading series into an image frame.

Wavelet Quality

Use default

Enabled

Use the default wavelet quality setting.

Lossless

Default

When using wavelet compression, use bit conserving quality factor.

N:1 Lossy

 

When using wavelet compression, terminate the decompression when the selected ratio is achieved.

Auto W/L Range

Use default

Enabled

Use the default automatic window/level range.

Distribution

95%

To eliminate the noise that may exist at the extreme ends of the distribution curve, reduce the data set to the defined distribution range.

Aggressive

Off except for MG, CR, DR

When set, the window and level values calculated from the data distribution reduce high occurrences of background noise. This makes the default values for projection images (CD, DR, MG) more dependent on image data.

Zoom mode

Use default

Enabled

Use default zoom mode.

Smart fit

Enabled

Maximize the anatomical structure in the image to fit the image frame and justify the image based on clinical expectations. Applies when the anatomical structure can be identified using available processing algorithms, such as skin line detection. Defaults to Fit to Window otherwise.

Fit to window

Default

Fit the image to the image frame. Use the interpolation algorithm selected for this modality type to create additional pixels.

1:1

 

Display only original pixel data, with no zoom factor applied.

 

Actual size

 

Display the image in the actual image size. This requires the monitors be calibrated for size before opening a study, and the image objects include pixel size information.
