Description of intervention(s) / exposure
This study involves the implementation of Respiratory Motion Guided (RMG) 4DCBCT for the first time on lung cancer patients. RMG-4DCBCT adapts the image acquisition as the patient’s breathing changes (i.e. if the patient breathes faster, imaging data is acquired faster). By adapting the acquisition to the moving patient, personalised images of a patients lungs are able to be acquired for radiotherapy treatments.
Additional equipment will be added to the radiotherapy treatment machine to allow for the RMG 4DCBCT scans. The images will be acquired on the day of treatment on two occasions (two separate days as close as possible to the beginning of the overall treatment) for 30 lung cancer patients. There is a total of 5 additional images per patient that will be acquired which means that the patient will be on the treatment couch for an additional 9 to 14 minutes in total. There is no other follow up required for the study following the acquisition of the images.
The intervention will be administrated by the treating radiation therapists and members of the medical physics team.

Outcomes
Primary outcome [1] 307111 0
To investigate the feasibility of acquiring RMG-4DCBCT for lung cancer patients undergoing radiotherapy. Each image will be scored by 4 experienced radiation therapists on a scale (1 poor image quality to 3 good image quality). Feasibility of RMG-4DCBCT will require an average image quality score for RMG-4DCBCT higher that is higher than conventional 4DCBCT.
Timepoint [1] 307111 0
At the end of each patients scan acquisition and end of the trial for overall comparison analysis
Secondary outcome [1] 350920 0
The proportion of patients with poor image quality for the largest and smallest 50% of patients based on hip width. Assessment is carried out after each imaging session.
Timepoint [1] 350920 0
At the end of each patients scan acquisition and end of the trial for overall comparison analysis. This will be completed by four experienced radiation therapists who are blinded to the acquisition method. Blinding to the acquisition method will be achieved by reconstructing the images offline and presenting the images to the radiation therapists in a random order.
Secondary outcome [2] 350921 0
The proportion of patients with poor image quality for peripheral and central tumours. Assessment is carried out after each imaging session.
Timepoint [2] 350921 0
At the end of each patients scan acquisition and end of the trial for overall comparison analysis. This will be completed by four experienced radiation therapists who are blinded to the acquisition method. Blinding to the acquisition method will be achieved by reconstructing the images offline and presenting the images to the radiation therapists in a random order.
Secondary outcome [3] 350922 0
The proportion of patients with poor image quality for the largest and smallest 50% of patients based on breathing amplitude. Assessment is carried out after each imaging session.
Timepoint [3] 350922 0
At the end of each patients scan acquisition and end of the trial for overall comparison analysis. This will be completed by four experienced radiation therapists who are blinded to the acquisition method. Blinding to the acquisition method will be achieved by reconstructing the images offline and presenting the images to the radiation therapists in a random order.
Secondary outcome [4] 350923 0
The proportion of patients with poor image quality for the largest and smallest 50% of patients based on breathing period. Assessment is carried out after each imaging session.
Timepoint [4] 350923 0
At the end of each patients scan acquisition and end of the trial for overall comparison analysis. This will be completed by four experienced radiation therapists who are blinded to the acquisition method. Blinding to the acquisition method will be achieved by reconstructing the images offline and presenting the images to the radiation therapists in a random order.
