1. A method for optical coherence tomography (OCT) imaging, comprising: obtaining first data comprising ophthalmic imaging data of a region of interest of a subject, the region of interest including at least one anatomical marker; generating an anatomical mask of the anatomical marker based on the imaging data by using a processor to execute an image processing technique; determining a scan path based at least in part on the mask, the scan path traversing at least a portion of an arbitrary enclosing shape at least partially fitted around the mask; and acquiring second data comprising three-dimensional (3D) OCT scan data corresponding to the scan path.
