The recommended way to prepare DICOM files for 3D modeling and surface reconstructions in PS is to create for each patient a folder named DCMTK which contains an HFS AXIAL study series with slice spacing < 1 mm and consisting of 16-bit MONOCHROME DICOM files with little endian Transfer Syntax UID (tag 0002,0010 = 1.2.840.10008.1.2) that have been converted to .xml file format. XML (Extensible Markup Language) is a modern, cross platform, native file format of MacOS that supports both text and embedded binary data (e.g. using base64 encoding) and hence is used extensively by both MacOS and all PS file operations. XML is a markup language similar to HTML, but without predefined tags. Instead, a user defines their own tags designed specifically for their needs. This is a powerful way to store data in a format that can be stored, searched, and easily shared over networks.
The DICOM toolkit DCMTK is a collection of cross platform libraries and applications implementing large parts the DICOM standard for Unix operating systems including MacOS. To install DCMTK you must first install a package manager for MacOS such as Homebrew. Follow the instructions on the Homebrew web site. Once you have installed Homebrew, you can then install DCMTK from a MacOS terminal window using the command brew install dcmtk. Be sure to make note of the Unix file path at which DCMTK was installed, it may differ slightly depending upon your version of MacOS. The file path is typically something like usr/local/bin. If you have successfully installed DCMTK and PS can find it, the indicator button on the right of the Multiplanar Reconstruction (MPR) window status line will be green. If the button is red you will need to customize the file path to DCMTK in PS Folders Preferences. Click the red button to take you to the folder preferences window.
