Description of intervention(s) / exposure
The study is looking at whether the Live View System (LVS) camera on the end of the Varian Halcyon treatment couch can be used for breath hold gating in comparison to the wall mounted real time position management (RPM) system that is currently being used. One treatment for each patient will be observed using both both the LVS system and the RPM system.

The LVS and RPM system both monitor the motion of a marker block placed on the patients chest. The main difference is that the LVS is obtaining the motion from the couch mounted video camera (otherwise known as the Liver View camera) whereas the RPM system uses a wall mounted dedicated infrared camera to obtain the patients breathing motion.

Data will be collected from patients that are already being treated using the RPM system as well as other patients who are receiving radiation therapy treatment.

For those patients where the RPM system is already being used in the patients treatment, data will be collected on both the RPM and LVS system during their treatment and will not take any additional time for the patient. Patients will be monitored for approximately 5 to 10 minutes for each patient.

If breath-hold-gating is not required as a part of the patients treatment, this cohort of patients will be asked to participate in a session separate from their treatment where their breathing can be monitored over a short period of time, providing data from both the LVS and RPM systems.

Summary
Brief summary
During radiation therapy treatment, some treatment machines have the ability to monitor a patients breathing patterns during treatment using a monitoring camera. A particular benefit of this treatment technique is for left sided breast patients as a deep breath (and hold) allows us to treat the breast cancer with reduced radiation dose to the heart.

In this study, we are looking at whether the patient monitoring camera on the end of the Varian Halcyon treatment machine couch (called a Live View System (LVS)) can be used to monitor patients breathing during treatment. This will be compared to the currently used breathing motion camera called the Real-time Position Management (RPM) System.

Who is it for?

You may be eligible for this study if you are an adult receiving radiation therapy treatment at an Icon Cancer Centre.

Study details
We are aiming to recruit at least 16 patients (32 patients in total) at each participating site in order to determine the effectiveness of the new camera based system. Data will be collected from patients that are already being treated using the RPM system as well as other patients who are receiving radiation therapy treatment.

This study will not impact the patients treatment in any way. For those patients where the RPM system is already being used in their treatment, data will be collected on both the RPM and LVS system during their treatment. The breath-hold-gating devices will collect the data during one daily treatment only and will not take any additional time for the patient.

If breath-hold-gating is not required as a part of the patients treatment, they will be asked to participate, in a session separate from their treatment where their breathing can be monitored over a short period of time, providing data from both systems that can then be compared.

It is intended that this research will contribute to the outcomes of patients by allowing motion management to be utilised on the Halcyon Linear Accelerator.
