The invention provides a remote surgical planning and navigating system. The remote surgical planning and navigating system comprises a medical image post-processing subsystem, a multi-mode image fusion subsystem, a medical image management subsystem, a surgical planning subsystem, a surgical navigation subsystem and a remote consultation subsystem, wherein the medical image post-processing subsystem is used for post-processing medical images; the multi-mode image fusion subsystem is used for fusing multi-mode images of a patient and carrying out three-dimensional reconstruction and visualization processing; the medical image management subsystem is used for storing and managing the medical images of the patient and establishing a personal file for the patient; the surgical planning subsystem is used for providing preoperative surgical simulations and plans; the surgical navigation subsystem is used for navigating a surgery; the remote consultation subsystem enables a surgical doctor and an imaging doctor to remotely cooperate and consult. According to the remote surgical planning and navigating system, data can be shared among different departments effectively, doctors in different departments can remotely communicate and cooperate, the problem of requirements for re-acquisition of scanned images which do not meet diagnosis requirements of the doctors is further effectively solved, and the efficiency and the success rate of the surgery are effectively improved.
