Effective radiation attenuation calibration for breast density: compression thickness influences and correction

Table 2 Bulge height and compression force regression analysis

Independent variable	Dependent variable	R-square	Intercept	Slope
compression force	bulge height (h_m)	0.84	0.069 cm	0.002 cm/N

This gives the regression summary for the 35 water filled phantom images. It shows the bulge height (h_m) is approximately a linear function of compression force.
