Brief Summary:
This clinical trial studies computed tomography (CT) in diagnosing patients with lung cancer. Diagnostic procedures, such as CT, may help find and diagnose lung cancer.

Condition or disease Intervention/treatment Phase
Lung Cancer Procedure: computed tomography Procedure: 4-dimensional computed tomography Procedure: cone-beam computed tomography Not Applicable

Detailed Description:

PRIMARY OBJECTIVES:

I. Conduct a prospective clinical imaging study to quantify the amount of inter- and intra-physician contouring variability on four dimensional (4D) CT, active breathing control (ABC) CT, free breathing CT, and free breathing and ABC cone beam (CB)CT.

II. Quantify the magnitude and distribution of target and organ at risk volume variations between the different imaging modalities.

III. Determine dosimetric changes related to contouring variations for tumor and normal tissue.

OUTLINE:

Patients undergo conventional free breathing CT, 4D CT, ABC CT, ABC CBCT, and free breathing CBCT before undergoing radiation therapy.
