MIPAV's anonymize feature allows you to remove information from a selected subset of DICOM tags. The tags in this subset are those indicated in DICOM Supplement 55: Attribute Level Confidentiality. These tags include, but are not limited to, the patient's name, ID, birth date, sex, ethnic group, referring physician, age, size, weight, and occupation.
You can also use the Anonymize command to anonymize several image series at one time. Refer to Figure 23, Figure 24, Figure 25, and Figure 26.
2 Select a starting or root directory, which is a starting point for the selection. You can then select the image subdirectories to anonymize.
3 Click Open. The Anonymize DICOM Directory dialog box opens.
4 In the Anonymize DICOM Directory dialog box, click File > New Directory. The Choose Directory dialog box opens. Refer to Figure 23-1.
5 Select one of the following:
6 Then, click Browse beside Image destination directory. The Select Destination Directory dialog box opens. See Figure 23-2.
7 Select a destination directory. See also a note on MIPAV_Dicom Images.
8 Click Select. The directory you selected appears in the Image destination directory box. It also replaces the name in the Translation/Key file destination directory box.
9 Now you can decide where to store the translation/key file.
translation/key file -records the original names in the files and correlates them to the new anonymous names. The name of the key file is patient.key.doc.
By default, the translation/key file is kept in the same directory as the images; however, if this is undesirable, you may choose a new location for the file. If you decide to change the location, go to the next step. If you decide against changing the location, go to step 12.

10 Click Browse beside Translation/Key file destination directory if you want to select another destination for the translation/key file. The Select Destination Directory dialog box opens. See Figure 23-3.
11 Use the dialog box options to browse you disk to select a designated catalog. Then click Select. The new destination appears in the Translation/Key File destination directory box.
The name of the anonymized files depend on the anonymous name, which is set later in step 14.
12 Click Tag Options to display the Tag Options page. See Figure 23-4.
The directory selection process on the Directory page provides the images to anonymize and the location of where to put them when done. However, it does not select what to remove from the images or what information to call the images when done. This is the goal of the Tag Options page. It allows you to choose the tags to remove from the images being processed and it gives you the opportunity to give an easily remembered name to the destination images.
13 Select the DICOM tags you want to anonymize. To select all of the tags, click Select all. To remove all of the tags, click Clear. See Figure 23-5.
14 Type the anonymous name for the image files in Anonymous name.
By default, a preset random value appears in Anonymous name, but you can replace this value with a more familiar name.
15 Type a value in Sequence beginning. When more than one image source directory is chosen, the sequence beginning number affects the name of the image file. The first image set is given the sequence number; the next image is given a number one higher.
The first image set is titled d0884_0. The second image set was chosen to be anonymized at the same time, it would be saved d0884_1.
16 Click Directory to return to the Directory page.
17 Select the directories in the Image source directory table that you want to anonymize.
18 Click Run. MIPAV displays the Logging page, where it displays messages about each of the images being processed until they are all processed. To stop the process, click Stop. The log appears in the Log tab. See See Figure 23-6.
19 To close the Anonymize DICOM Directory window after all images are processed, click Close.
The number of image directories chosen affect precisely where the processed images are stored. When one directory is chosen as the source in all anonymized DICOM files are placed directly in the chosen destination directory. However, selecting more than one source directory in step 17, the anonymized DICOM files are placed into subdirectories of the Destination directory (refer to the following table).
