Sentinel node resolvability. A. Schematically representation of the phantom setup. The injection site was simulated using 4×25 MBq 99mTc-pertechenetate sources placed in a diamond. The sentinel node (SN) was simulated with a 1 MBq 99mTc-pertechenetate source. Injection site-to-SN distance was varied in steps of 10 mm (range 10-80 mm). B. 2D-flatbed images at a source-detector depth of 60 mm (acquisition time: five min). SNs were placed at 20, 40, 60 and 80 mm injection-site to SN distance at 60 mm depth (upper panel) and 10, 30, 50 and 70 mm at 12 mm depth (lower panel). C. SN resolvability for SNs at various injection site-to-SN distances and various source-detector depths for 2D-flatbed imaging (blue), 2D-MGC imaging (green), and 3D-FHS-MGC (red).
