Bland-Altman analysis for the intrafractional motions recognized by fiducial marker matching with kV fiducial on-board imaging vs. soft tissue matching with kV cone-beam computed tomography for 206 pre-treatment datasets in the anterior to posterior (AP), superior to inferior (SI), and left to right (LR) directions. The bubble size represents the data numbers with the same values, as shown on the right top outside of each graph. The vertical axes are depicted as the difference with (the intrafractional error recognized by soft tissue matching with cone-beam computed tomography) minus (the intrafractional error recognized by fiducial matching with kV on-board imaging)
