Hybrid Modality Fusion of Planar Scintigrams and CT Topograms to Localize Sentinel Lymph Nodes in Breast Lymphoscintigraphy: Technical Description and Phantom Studies
Figure 4
Measured spatial distortion of CT topogram. The error in lateral distance from isocenter (measured-true) of a point object (mammography bead) varied linearly as a function of both the lateral and coronal distance from isocenter.
