Assessment of Iterative Closest Point Registration Accuracy for Different Phantom Surfaces Captured by an Optical 3D Sensor in Radiotherapy

Figure 3

An example of the AlignRT monitoring screen seen during measurement of the torso phantom and vertical shift of the treatment table = 10 mm. The reference surface is shown in pink and the measured surface in green. The suggested linear translations (vertical, lateral, and longitudinal) and rotations (yaw, pitch, and roll) are shown by numbers and colored bars on the left together with the RMS value (called magnitude MAG). The white graph is used to display a time series of the RMS values (not used in our experiment).
