Open a DICOM file (Photoshop Extended)
Before you open a DICOM file, you can specify how DICOM frames are opened (as layers or in a grid), and set
options (in the DICOM File Import dialog box) that anonymize patient metadata and display overlays. Once you
open the file in Photoshop, you can perform pans, zooms, and window leveling.
The DICOM import dialog box also displays DICOM header information—textual information about the file, such
as its dimensions, data resolution, and whether or not the data has been compressed.
You can import a sequence of multiple, single-frame DICOM files into a single multilayered Photoshop file, using the
New Video Layer from File command. See “Import image sequences (Photoshop Extended)” on page 554

Windowing
Adjust the contrast and brightness of the frame with windowing options. Select Show Windowing
Options, and adjust window width (contrast) and level (brightness) by entering values in the Window Level or
Window Width boxes. Alternatively, you can drag the Window Level tool up or down to adjust the level, or to the
right or left to adjust the width. You can also choose common radiology presets from the Window Preset menu
(Default, Lung, Bone, or Abdomen). Select Reverse Image to invert the brightness values of the frame.
To zoom, choose a zoom level from the Select Zoom Level menu (or click the plus and minus symbols to zoom in and
