What this trial is about
This study does not involve a therapeutic intervention as standard radiation therapy treatment will be prescribed. This study involves one additional 4DCT scan (i.e. the Real-Time Gated 4DCT scan) acquired immediately before or following the conventional 4DCT scan. This will take place on the day of the patient's treatment simulation, as per the current standard of care. The scanning sequence (i.e. conventional first versus gated first) will be randomised. The Real-Time Gated 4DCT is anticipated to take longer than the conventional 4DCT scan, due to its gated (beam-pause) nature. However, upper limits for timing will be implemented in the software, and the scan aborted for highly erratic breathing traces that would not benefit from a Real-Time Gated 4DCT scan.
