Official title

4D(Dimensional) CBCT (Cone-beam Computed Tomography) and Intrafractional Imaging for the Determination of the Most Representative 4D Simulation Planning Technique for Lung SBRT (Stereotactic Body Radiation Therapy) Technique Patients

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The researchers plan to investigate two ways of visualizing and planning to account for the respiratory motion which takes place while treating lung tumors with radiation therapy. The researchers will determine if a traditional snapshot (free-breathing) CT or a longer-lasting CT encompassing the breathing cycle better matches a patient's breathing during treatment.
