Setup Variation in the Supraclavicular Lymph Nodes Treatment in Breast Cancer Patients
The goal of this clinical research study is to use the On Board Imager kilovoltage (OBI KV) system and cone beam computed tomography (CBCT) scanning or CT-on-rail system to look at how well a routine device called an electronic portal imaging device (EPID) can set up a patient to receive radiation therapy on the lymph nodes in the neck.

|Official Title:||A Pilot Study of Setup Variation in the Supraclavicular Lymph Nodes Treatment in Breast Cancer Patients Using On-Board Imaging System With Linear Accelerator|
- System Failure (defined as 2 or more disagreements between the EPID and either OBI systems or CT-on-rail from among the 5 evaluations for a particular patient) [ Time Frame: CBCT scanning and OBI R or CT-on-rial system, 5 evaluations per patient, during 5-week radiation treatment period ] [ Designated as safety issue: No ]

|Primary Completion Date:||October 2014 (Final data collection date for primary outcome measure)|
OBI KV System + CBCT Scanning
Breast cancer patient radiation treatment set up using OBI KV system and CBCT scanning or CT-on-rail system to verify standard EPID for positioning.
Procedure: CBCT Scan
Cone Beam Computed Tomography (CBCT) scan performed once a week.Procedure: OBI KV Imaging
On Board Imager kilovoltage (OBI KV) Imaging performed once a week.
