Eleven marker templates were printed onto a Lycra shirt, ensuring tight fit on the volunteers, while position of the markers correspond to areas relevant for the measurement. To acquire respiratory motion traces, a special marker shirt has been developed. In this work, we demonstrate how consumer hardware (Microsoft’s Kinect v2 depth sensor) can be used to accurately track the 3D position of multiple markers using a special marker shirt. It has been shown that the accuracy of these correlation algorithms can be improved by incorporating multiple markers. Although this could be done (either using continuous X-ray localisation or 3D ultrasound tracking ), the current method in clinical use relies on a mathematical model linking the motion on the patient’s chest to the motion of the actual target. Especially in the second scenario, tracking one marker may not be sufficient: the actual target of the treatment beam – the tumour – is typically not observed directly.

Subsequently, trajectory of the marker is then analysed and used to either dynamically activate the treatment beam (called gating ) or to guide the radiation source. As an example, image-guided radiotherapy (IGRT) of the chest and abdomen relies heavily on this principle: some kind of marker is placed on or attached to the patient’s chest and is monitored using a non-invasive localisation device. In many clinical applications, detecting and tracking of respiratory motion is required.
