If images from a particular station come into the system at the wrong orientation (according to the radiologists’ preferences), you can create a field mapping to flip these images automatically. This could be useful, for example, for mammography images that are not viewed using the Comparative Review Modes.
To create a field mapping to flip images automatically
On the Setup tab, click Source Manager.
Switch to the Field Mappings tab.
From the station table at the bottom of the tab, select the acquisition station to customize.
If the required station is not listed, switch to the Description tab and add it.
Click New Mapping.
In the New Mapping dialog, from the Attribute Class list, select object.
From the Attribute Name list, select mitra_rotation.
In the Attribute Expression field, type the correct expression for the station.
What the mapping checks for Expression to use L CC or L MLO in series description select( index( getdicomstring(0x0008103e), 'L CC', 'L MLO', getdicomstring(0x0008103e) ), '4', '4', '0' ) L in laterality select( index( getdicomstring(0x00200060), 'L', getdicomstring(0x00200060) ), '4', '0' ) 
Note:
In the first example, the values that the index statement is looking for are exact and case-sensitive—for example, L CC is not the same as LCC or l cc. Ensure that the mapping is created using the exact value that may appear in the DICOM information from the station.
To close the dialog, click OK.
Click Save.
