Summary
Brief summary (as posted)
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.

- label
- OBI KV System + CBCT Scanning
- description
- 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.
- interventionNames
- Procedure: CBCT Scan
- Procedure: OBI KV Imaging
Primary outcomes (1)
- measure
- 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)
- timeFrame
- CBCT scanning and OBI R or CT-on-rial system, 5 evaluations per patient, during 5-week radiation treatment period

Inclusion Criteria: 1. Histologically confirmed carcinoma of the breast. 2. American Joint Committee on Cancer (AJCC) Stage I-III, or locally recurrent breast cancer 3. Planned for radiation treatment of the supraclavicular and axillary apex nodal beds using a SCV field 4. Age greater than or equal to 18 years, since classic breast cancer is a disease of adults 5. Able to understand the current trial and give informed consent Exclusion Criteria: 1. Has bilateral breast cancer requiring radiation to both breasts due to anatomic constraints on planning CT 2. inflammatory carcinoma due to altered treatment schedule
