Fig. 5From: Accuracy of an MR-only workflow for prostate radiotherapy using semi-automatically burned-in fiducial markersCumulative histograms of the SD of the RL-, CC- and AP-component of the COM position of FMs consisting the one (blue), six (green) and twelve (red) voxels with the lowest signals. The vertical axis shows the percentage of FMs with a SD more than the value given on the horizontal axis. Example: for the SD of AP for 3% of the FMs the SD of the AP-component of the FM position was larger than 0.5 mmBack to article page
