Change modality preferences

You can change NilRead settings for different modalities.

Note
If you access Settings while viewing a study, select Back to Viewer to return to the image viewing area.

1. Select Settings.
2. Under Preferences, select Modality Preferences.
3. Enter the following information, then select Save.

Modality

Select the modality that you want to set preferences for. The changes you make on the Modality Preferences page will only affect studies containing this modality. Select All to apply the changes to all modalities. Note that if you set a preference for an individual modality, this will override the same preference set for all modalities.

Series Navigation

Determines the behavior of the Scroll tool. By default, the Scroll tool will scroll through images in the current series only.

• None  Scroll through the current series only.
• Single Frame Only  Scroll through all of the series in the study. When advancing to the next series, scroll through single frame images only (omit multiframe images).
• All  Scroll through all of the series in the study. When advancing to the next series, scroll through all images (single frame and multiframe).

Virtual Series

Determines whether a virtual series is automatically created for a study.

• Select Yes to automatically create virtual series.
• Select No if you do not want to create virtual series.

Zoom Policy

Determines the behavior of the Zoom tool.

• Zoom at center  Zoom will be applied at the center of the viewport, regardless of where you click (or tap) on the image with the Zoom tool.
• Relative zoom at mouse position  Zoom will be applied at the point where you click (or tap) on the image with the Zoom tool. This is the default setting for mammography images.

Old Study Warning

A warning is displayed in the viewport if an image is older than the specified number of days. The default value for mammography images is 365 days. The default value for other modalities is 0, meaning a warning will not be displayed.

Cine Sequence

Determines whether cine sequences are played automatically when the cine sequence is loaded in the viewport.

Window level presets

(Available for some modalities only) You can change the window level presets for different modalities. For details, see Change window level presets.

Image Ruler Options

(Available for some modalities only) Determines how the image ruler size is controlled. Rulers can only be displayed when the underlying meta-data provides known and consistent pixel spacing and image geometry is flat.

• Scope  (Administrators only) Choose whether the settings apply to the entire site (Site Defaults) or to your account (User).
• Basis  Choose how the ruler size is controlled. Viewport basis constrains the ruler to fit in the viewport (typically 60%). Different ruler lengths can be chosen while zooming the image. Image basis keeps the ruler size constant independent of zoom; however, the ruler may extend beyond the viewport size under certain zoom factors.

Note
NilRead users can use Titles to show or hide a ruler for an image (see Titles). Administrators can choose whether rulers are shown by default (see Ruler display settings).
