Imaging Study on Halcyon 4.0 System for Patients Receiving Radiation Therapy

This prospective imaging study is evaluating the feasibility of using the Halcyon 4.0 radiotherapy system for radiation therapy planning in patients with cancer. The Halcyon 4.0 system has been engineered to decrease the image acquisition time and the radiation exposure, but the system has not yet been clinically validated for use in radiation planning. This pilot study will evaluate images obtained on the Halcyon 4.0 system to assess if the quality is sufficient for radiation treatment plan construction.
