Figure 7:

Real-time volumetric liver tumor motion tracking by using the MR Signature Matching technique for two representative sections. The tumor contour is shown in red. The motion-signal row shows the temporal location (green point) in the respiratory motion signal. Total imaging latency including data acquisition and image reconstruction for each three-dimensional image is about 250 msec. Access to real-time volumetric motion information would in principle allow continuous adaptation of the radiation beam to the tumor motion.
