3D and technical imaging
Last updated 1/10/2010
After creating frames in the (Animation) Timeline panel, you can save DICOM files as QuickTime movies (change
grayscale DICOM files to RGB, and then render to video). You can also save frames as animated GIF files (choose
File
> Save for Web and Devices).
You can also use the Timeline panel to animate a 3D volume created from a DICOM file. See “ Create 3D animations
(Photoshop Extended) ” on page 598.

Measurement (Photoshop Extended)
About measurement (Photoshop Extended)
Using the Photoshop Extended Measurement feature you can measure any area defined with the Ruler tool or with a
selection tool, including irregular areas selected with the Lasso, Quick Select, or Magic Wand tools. You can also
compute the height, width, area, and perimeter, or track measurements of one image or multiple images. Measurement
data is recorded in the Measurement Log panel. You can customize the Measurement Log columns, sort data within
columns, and export data from the log to a tab-delimited, Unicode text file.
For a video on measurement features, see www.adobe.com/go/vid0029 .
Measurement scale
Setting a measurement scale sets a specified number of pixels in the image equal to a number of scale units, such as
inches, millimeters, or microns. Once you’ve created a scale, you can measure areas and receive calculations and log
results in the selected scale units. You can create multiple measurement scale presets, although only one scale can be
used in a document at a time.
Scale markers
You can place scale markers on an image to display the measurement scale. Scale markers can appear with or without
a caption displaying measurement scale units.

Note: Measurement scale is set automatically for DICOM files. See “ About DICOM files (Photoshop Extended) ” on
page 603.
Choose Analysis > Set Measurement Scale > Default to return to the default measurement scale, 1 pixel = 1 pixel.
