Abstract
A method includes capturing a first set of optical images of the subject while a subject is lying on a table of a Magnetic Resonance (MR) scanner. This first set of optical images is acquired without any MR phased-array coils placed on the subject. While the subject continues to lie on the table of the MR scanner, a second set of optical images of the subject is acquired with the MR phased-array coils placed on the subject. Aside from the optical images, a set of MR images of the subject is acquired using the MR scanner. The first and second set of optical images are registered to the MR images. Following registration, the first and second set of optical images are used to determine element positioning of the MR phased-array coils in the set of MR images.
