An implantable lead for an electrical stimulation system includes a lead body having a distal end, a proximal end, a longitudinal length, and a circumference； a plurality of electrodes disposed along the distal end of the lead body in an electrode array； a plurality of terminals disposed along the proximal end of the lead body； a plurality of conductors electrically coupling the plurality of electrodes to the plurality of terminals； and at least one capsule including an x-ray fluorescent material and disposed along the distal end of the lead body relative to the electrode array to indicate, when viewed fluoroscopically, an orientation of the electrode array. The plurality of electrodes includes a plurality of segmented electrodes. Each of the plurality of segmented electrodes extends partially around the circumference of the lead body.
