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
For a video on opening DICOM files, see
Choose File > Open, select a DICOM file, and click Open.
