The medical web viewer and the medical web service implement advanced support for the DICOM Hanging Protocol as defined by the DICOM standard (for more information, refer to DICOM PS3.17-V Hanging Protocols).
Unlike a presentation state (which includes manipulations specific to a particular patient’s images), a hanging protocol is simply a generic set of rules (the "protocol") describing how to lay out a set of images for viewing ("hanging", which refers to hanging the films on a lightbox).
A hanging protocol describes what to display (attributes and conditions, including modality, anatomy, laterality, procedure, and reason). It also defines how to display a set of images (window-leveling and width, rotation, tiling, etc.)
Using hanging protocols speed up diagnosis and reduce mistakes:
There are two basic steps for using a hanging protocol:
In the medical web viewer, click the Compose Layout button (
Perform image and layout manipulations:
Invert the color order, flip, rotate, or reverse the image to match the desired view
Align the images or lay out tile configuration
Set scrolling options for multi-frame images, or stack images for cine operation
Create orthogonal slices by clicking the MPR button
Turn on reference lines or synchronized stacking for volumetric studies.
Perform the following steps to load a hanging protocol:
In the Search View, right-click a study to display a menu of compatible hanging protocols, and select an item from the menu to open the view with the hanging protocl applied.
The medical viewer will save the hanging protocols you created to a standard DICOM dataset file, meaning you can share this hanging protocol with any other PACS server that supports this feature. Files are stored in your LEADTOOLS Storage Server manager (Storage Settings -> Files -> Hanging Protocol)
