Example of beam hold data for a lung cancer patient; 1 is beam-on and 0 is beam-off.
(a) Data of trajectory log file. (b) Original raw data of the motion wave file. The parts to be truncated are indicated as the gray areas. (c) Data of the motion wave file after data processing, including truncation, rescaling, and resampling. (d) Synchronized data for two beam hold data types.
