12. A method for catheter navigation, comprising:
obtaining at least one real-time image associated with a subject, the at least one real-time image including a catheter at least partially inside the subject;
determining spatial position information associated with the catheter based on the at least one real-time image;
directing a display device to configure a virtual object corresponding to the catheter in a reference image associated with the subject based on the spatial position information;
determining whether the subject satisfies a preset condition during an operation associated with the subject based on the at least one real-time image or the reference image, the preset condition being related to a distribution of the subject within a predetermined range of a front end of the catheter, wherein the subject is a vessel and the preset condition is that a distribution of the vessel within the predetermined range of the front end of the catheter presents vessel bifurcation or vessel overlapping; and
in response to determining that the subject satisfies the preset condition during the operation, directing an acquisition device corresponding to the at least one real-time image to turn off at least a part of the acquisition device, the at least a part of the acquisition device is configured to obtain an image, and keep a remaining part of the acquisition device on, the remaining part of the acquisition device is configured to obtain an image.
