Study Summary
In this study, the researchers investigate the feasibility of using rapid cine MR imaging to provide both offline and online soft-tissue-based image guidance. Such images will provide a significantly more complete picture of the spatial and temporal changes in thoracic anatomy. This more complete information will lay the groundwork for better radiotherapy planning and dose delivery in the presence of respiratory motion.
Primary Outcome
To use fast acquisition sequences to obtain 2D and 3D cine MR images of moving and deforming lung tumors. The signal to noise ration (SNR) and spatiotemporal resolution of imaging sequences will be optimized into a format potentially useful for radiotherapy guidance.
Interventions
