Official study title

4D CBCT and Intrafractional Imaging for the Determination of the Most Representative 4D Simulation Planning Technique for Lung SBRT Technique Patients

Study summary

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.

Public criteria

Who may be able to participate

The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.

Requirements people may need to meetInclusion criteria
  • Age ≥ 18 years.
  • Ability to provide informed written consent in either English or Spanish.
  • Patients with cancer or presumed cancer involving the lung (primary or secondary) planned to undergo lung SBRT technique or IMRT technique with an SBRT setup in 10 or fewer fractions.
Reasons someone may not be able to joinExclusion criteria
  • Current pregnancy, as this is a contraindication to receiving radiation therapy.
  • Patients to be treated to multiple targets concurrently.
  • Any condition or history as evidenced by patient record and/or self-report that, in the opinion of the investigator, would interfere with adherence to the prescribed pattern of radiation therapy.
  • Poor lung function, as judged by the prescribing radiation oncologist, sufficiently limiting to make the patient not a candidate for 4D imaging (for example major differences between the 4D and free-breathing CT scan).

Important: This is the sponsor’s public criteria, not a determination of eligibility. The study team must review your individual situation.
