- The calibration regression parameter distribution means <μ> and standard deviations (parenthetical entries) for the pure water and oil deformable phantoms are tabulated. The subscripts (s, r, nc) define (1) quantities generated from the narrow strips (s) shown in Figure 4, (2) quantities generated from the larger region (r) of interest (25 cm2) using the compression thickness correction, and (3) quantities generated from the larger region of interest without applying the correction (nc) using the system thickness readout values, respectively.
