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)
