* This app works when coupled with its sister app, the Patient Tracker PCPT iOS Client (Patient Tracker PCPT in the app store). Patient Tracker PCPT is a simple app to stream live 1080p feeds of a patient to be positioned to the Mac Client, where the entirety of the treatment workflow occurs. After positioning the iOS devices this app runs on and launching the apps - and giving required permissions - no more interaction is required with the iOS devices. Align live videos with previously acquired images, or go into offline mode to compare multiple previously acquired images.
