To quickly scroll through frames, use the mouse scroll wheel (Windows) or click the Right or Left Arrow buttons below the large preview
area.
3. Choose from the following options, and then click Open.
Import Frames As Layers places DICOM frames on layers. N-Up Configuration displays multiple frames in a grid (enter
values in the Rows and Columns boxes to specify height and width of grid). Import as volume opens the DICOM frames as a volume, where
the z-distance is determined by DICOM settings and data is interpolated between the frames. You can view the volume from any angle,
using a variety of rendering modes to highlight data.
Anonymize overwrites patient metadata with “anonymize.” Show Overlays displays overlays such as annotations, curves,
or text.
Select Show Windowing Options to adjust the contrast (Window Width) and brightness (Window Level) of the frame.
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 signs to zoom in and out). To pan, click
the Hand icon at the top of the dialog box and drag across the frame.
Create a 3D volume from DICOM frames (Photoshop Extended)
1. Choose File > Open, select a DICOM file, and click Open.
2. Select the frames you want to convert to a 3D volume. Shift-click to select contiguous frames. To select noncontiguous frames, Ctrl-click
(Windows) or Command-click (Mac OS). Click Select All to select all frames.
3. In Frame Import Options, select Import as volume, then click Open.
Photoshop creates a 3D volume of the DICOM frames and places it on a 3D layer in the Layers panel. You can use Photoshop’s 3D position tools
to view the 3D volume from any angle, or change render settings to better visualize data.
The original DICOM file is preserved as a Diffuse texture layer associated with the 3D volume layer. For information on 3D textures, see 3D
texture editing (Photoshop Extended).
Double-click the texture layer to open the DICOM file as a Smart Object in its own document window. The DICOM frames appear as separate
layers in the Layers panel.
Any changes you make to individual layers are applied to the 3D volume when you close and save the Smart Object.
To save the 3D volume, you can export the 3D layer or save the file in PSD format. See Saving and exporting 3D files (Photoshop Extended).

1:30 mark.)
