The Info list contains calculated values, generated by the viewer and based on the loaded study. The list of available values in the Info list is as follows:

Info Field	Description
Augmentation	Processed keyword value used by hanging protocol assistant to identify the series description.
Completion	The percentage of the image that has already downloaded to the viewer.
Compression	The compression ratio applied to the image.
Current Annotation	If an annotation is currently selected, the value of that annotation (i.e., the length, area, text string, etc.) appears in the overlay.
HP Series Info	Hanging protocol’s matching criteria information.
Image Index	The position of the image in the series. This is different from the Instance Number in the Tag list. The Instance Number is a value defined by the modality, and is not guaranteed to be sequential. The Image Index uses the position in the series, and therefore is always sequential.
Level	Current window center setting.
Packet Size	Size of the network packets in the download transmission.
Primary Status	Displays one of the following values: Current – the image is an object in the primary study. Prior <N> – the image is an object in a related prior (to the primary study). The number, N, represents one less than the ordinal value of the study in the thumbnail panel. Unrelated – the image is unrelated to the primary study.
Renderer	Image rendering method: sw (software), bd (hardware) or d3d (Direct3D).
Series Size	Total number of images in the series.
Window	Current window width setting.
Zoom	The zoom factor currently applied to the image.

To access data within a DICOM sequence, use viewer coercion to extract the information into a user or custom field, and then apply that field to the DICOM Field configuration.

The Thumbnail panel header information can be customized by editing the Thumbnail study header, series headers and overlay data. Select the respective field from the Display Location list and add tag, info and text fields as needed. The series header, footer, top overlay and bottom overlay fields are limited to a single line. The value is truncated if too long. Truncated series header and footer values are displayed by positioning the mouse over the field. If the series header or footer location is empty, the field is hidden in the Thumbnail panel.

For studies with a Modality value of MG, the display location refers to the anterior and posterior sides of the image. On these images, the overlay information is relative to the image and not the image frame. If the viewer cannot detect the anterior and posterior edge of the mammography image, the associated left or right location shall apply.

The font characteristics of the data displayed as image overlay, thumbnail study header and series headers and footers, and the thumbnail top/bottom locations can customized individually. The default colors are defined in the Customize Settings Color panel. The default font size is defined in the Character Size field in this panel. Field-specific settings override these. To customize a specific field, do the following:

Select the field in the field list on the left. This enabled the available font characteristic buttons. If a button remains disabled, the setting is unavailable for the selected location.
Click the characteristic button.
If a setting-specific window pops up, select the specific value and click OK. Two control strings are inserted into the field list area immediately before and after the selected field.
To expand the setting across multiple fields, select the control string and click the Move Up or Move Down until the control string encompasses the intended fields.

You can embed multiple font settings within existing control entries.

To remove a font control setting, you must remove both the preceding and trailing control entries, as follows:

Select the preceding control entry.
Click the Remove button.
Select the trailing control entry.
Click the Remove button.
