Figure 3From: Evaluation of inter-observer variability of bladder boundary delineation on cone-beam CTThe standard deviation (SD) of the center of mass (COM) displacement value of the structure along each direction. The horizontal solid line indicates the root mean square (RMS) of the overall SD (σ) of the bladders and prostates. The dotted line and dashed line indicate the σ of the female bladders and male bladders, respectively.Back to article page
