Table 1.

Phantom shift tracking experiment results. ε represents the difference in magnitudes of shift observed in physical-space and shift calculated via the shift-tracking protocol. Initial deformation magnitudes (d_exp) are reported from the physical-space measurements provided by the OPTOTRAK system.
