This is an example of a simple hanging protocol that will be applied to all studies containing any CR images and will put the first CR image of the primary and prior studies into a 1x1 grid and the remaining images of the primary study into 2x2 grids:

<hanging-protocols>
    <hanging-protocol residual-workspace-rows="2" residual-workspace-columns="2" >
        <study-filter>
            <condition>
                <contains test="$ModalitiesInStudy" pattern="CR" />
            </condition>
        </study-filter>
        <image-filter name="CR">
            <condition>
                <equal test="$Modality" refValue="CR" />
            </condition>
        </image-filter>
        <workspace rows="1" columns="1">            
            <image-box filter="CR" />
        </workspace>
        <workspace rows="1" columns="1">            
            <image-box filter="CR" prior-study="true" />
        </workspace>
    </hanging-protocol>
</hanging-protocols>            

The condition elements work like descriped at Rule Condition Operators within the ClearCanvas ImageServer User's Guide.
