Photograph of the platinum fiducial marker (LumiCoil), which is 10 × 0.46 mm (0.018 inch) in size, can be loaded into a 22G endoscopic ultrasound needle, and coils into a figure eight-like configuration upon deployment.

Fig. 2
Endoscopic ultrasound (EUS) images showing the fiducial markers, visible as bright echoes (arrows) in the center of pancreatic metastases from renal cell carcinoma, which are seen as hypoechoic tumors in the: a pancreatic tail (22 × 21 mm in size); b pancreatic head (9 × 8 mm in size).

Fig. 3
Computed tomography image used for radiotherapy planning showing the fiducial marker (encircled in green) implanted in the tumor of the pancreatic tail (encircled in red). Organs at risk (stomach, bowel) are marked in blue.
Fig. 4
Fig. 4
Cone-beam computed tomography (CBCT) image showing the fiducial marker implanted in the tumor of the pancreatic tail (encircled in red). The tumor itself is not visible, because of the low soft tissue contrast resolution of CBCT imaging; the radiopaque marker is essential for target volume localization. CBCT is performed before delivery of each radiation fraction to verify the target position.
