Markerless Image Guidance Using Intrafraction Kolovoltage X-ray Imaging for Lung Cancer Radiotherapy

In radiotherapy, tumour tracking allows us to ensure the radiation beam is accurately targeting the tumour while it moves in a complex and unpredictable way. Most tumour tracking techniques require the implantation of fiducial markers around the tumour. Markerless Tumour Tracking negates the need for implanted markers, enabling accurate and optimal cancer radiotherapy in a non-invasive way.
