Figures

Image of FIG. 1.
FIG. 1.

(a) An ultrasound image from a localization US dataset of a prostate patient; (b) a 2 MU-AP portal image of fiducial markers; (c) an axial MV-CBCT image of a prostate patient localized with CB, using at isocenter.

Image of FIG. 2.
FIG. 2.

Patient mean shift in all three directions for each localization device, along with the overall population mean shift (solid horizontal line) and standard deviation (dashed horizontal lines). One very large patient, whose skin markers were unreliable, was removed from the CBCT data set (open circle).

FIG. 3.

Scatter plots of the localization data. (a) US AP view; (b) US SI view; (c) US LR view; (d) MV-CBCT AP view; (e) MV-CBCT SI view; (f) MV-CBCT LR view; (g) SM AP view; (h) SM SI view; (i) SM LR view.

Histogram of the mean 3D shift values. (a) US data; (b) MV-CBCT data; (c) SM data.
