Image Stacks

Study Stack

When the study stack option is selected, all series with the same series description from a single study, prior studies or all studies will be loaded into an available image frame or a selected frame.

To open a study stack:

Select Layout/Stack/Study Stack
Press CTRL and double clicking the left mouse button on the thumbnail study header

Prior Stack

When the prior stack option is selected, all studies labeled as priors will be loaded into an available image frame or selected frame. This includes all open prior studies in the session.

To open a prior stack:

Select Layout/Stack/Prior Stack

Session Stack

When the session stack option is selected, all series from all studies will load into an available image frame or a selected frame.

To open a session stack:

Press CTRL + SHIFT and double click the left mouse button
Select Layout/Stacks/Session Stack

Series Stack

When opening a series stack, images will open into an available image or a selected frame that contain the same criteria:

View position and laterality will be the same
Studies will have the same series descriptions

There are three options available when loading a series stack:

Series Stack	Description
Study	Includes series from the selected study having the same series description as the selected series.
Prior	Includes series from a prior study having the same description as the selected series.
Session	Includes series from all studies having the same description as the selected series.

See: Hanging Protocols

Unviewed Stack

There are four options available when loading unviewed images on to the next available image frame:

Unviewed Stacks	Description
Primary	Will load primary studies with unviewed images
Selected Study	Will load selected study with unviewed images
Stack Prior	Will load prior studies with unviewed images
Stack Session	Will load all unviewed series from all studies

To access these options:

CTRL + ALT + SHIFT and double click the left mouse button in the thumbnail study header (for primary only)
Layout/Stack

Note: The image thumbnail will contain the unviewed status indicator.

See: Thumbnail Status Indicators

Load Next/Previous Prior

This option will load an image from the next available prior study with the same study description. There are keyboard shortcuts available as well: Ctrl + Page Up and Ctrl + Page Down.

Note: At least two prior studies must be opened.

Cyclic Image Scrolling

The Cyclic Image scrolling is located in the Settings panel under Frames/Views/Controls.

Enabled - the viewer loops to the first prior study
Disabled - the viewer stops loading priors

If multiple prior studies are included in the current display layout, the image frame is cleared if there is no next prior. When the last prior is loaded into the image frame, the viewer will stop loading priors. The primary study will not be loaded using the next/previous prior tool.

When replacing the prior study, the viewer loads the series based on the hanging protocol identifiers such as the Series Description. If the study does not contain a series equivalent to that of the loaded prior, the image frame will remain blank but the HP information is retained so the frame will be populated accordingly with the next prior.
