A transfer module, such as a single board computer having wireless communication capabilities, may be attached to an image guided surgery (“IGS”) navigation system. Images, video, and data stored on the IGS navigation system may be moved to and stored on the transfer module in an encrypted format. The transfer module may connect to a secure network or other secure wireless communication and transfer encrypted IGS medical procedure data to a physician device, a hospital system device, or other device. After validation, the physician device or other device may decrypt and display the data. The transfer module may be useful for IGS navigation systems having no preexisting wireless capabilities; and for those having wireless capabilities that are less secure than those provided by the modified IGS navigation system. The transfer module may also wirelessly transmit IGS medical procedure data to a cloud storage system for subsequent access by end users.
