DICOM browser lists' unread items… Determines the font color of unread items listed in the Manage DICOM Images dialog. DICOM browser lists' series that contain sub-series… Determines the font color of items in the Manage DICOM Images dialog that contain sub-series. A DICOM series is an image or a group of images acquired from a single modality during a single encounter. A sub-series can be defined as a series in which a specified field has more than one discreet value. For example, a series that has two different Echo numbers may be two different acquisitions that were mistakenly stored together. Attribute browser's list items that are sequences… Determines the font color of data fields that contain multiple data elements in the DICOM Attributes dialog. The DICOM standard allows an attribute to contain multiple data elements. This means that the value of a data element may contain a number of items. Data elements that contain nested items are called Sequences and a single element that is nested within a sequence is called a Sequence Item.
Draw text annotations shadow	If selected, shadows will appear under text annotations.

	Description
Interpolation	Determines the interpolation applied to images in 2D views. Nearest… Is the most basic interpolation scheme and only considers one pixel when filtering. Linear… Considers the closest 2x2 neighborhood and then takes a weighted average of these 4 pixels to arrive at its final interpolated value. Will result in smoother looking images than Nearest.
Show text annotations	If selected, text annotations will be shown in 2D and 3D views by default.
Show scale bar	If selected, a floating scale bar will appear in 2D views by default (see Scale Bar).
Show legend	If selected, legends will appear in 2D and 3D views be default (see Legends).
LOD in 2D	If selected, the level of detail for 2D views may be diminished during movement. In general, selecting this option will increase speed during manipulations.
Zoom at cursor position	If selected, zooming will be implemented at the current position of the mouse cursor. This allows you to easily zoom on a given feature without first shifting the image to the center of the view. If not selected, zooming is implemented from the center of the view.
Cine increment	Determines how stacking through displays in Slab mode is implemented (see Working in Slab Mode). Single image… Stacks through all slices in the dataset. Half slab… Stacks through half the thickness value selected for slice integration. Full slab… Stacks through the full thickness value selected for slice integration.

	Description
Line thickness	Determines the thickness of non-text annotations, such as lines, angles, and so on, as a screen percentage.
Legend outline thickness	Determines the thickness of legend outlines, as a screen percentage.
Mouse grab tolerance (in pixels)	Determines the sensitivity of the mouse around object boundaries. The smaller the number, the more accurate you need to be to select an object. For example, a value of 0 means that the mouse needs to be exactly over a line in order to select it. Changing the value to 2 means that if the cursor is 1 or 2 pixels away from the same line you would still be able to select it. Enter a new value in the edit box to modify.
