NCT00911456
Brief Summary:
To determine if the Clarity 3DUS (3D Ultrasound) system can be used by multiple individuals to acquire 3DUS images and produce consistent TB (Tumor Bed) shifts for breast IGRT (Image-Guided Radiation Therapy).
Detailed Description:
TB Contouring The CT1, CT2, and US1 tumor beds will be manually contoured on the RM workstation by one of the study radiation therapists. Contouring will be performed using previously defined contouring guidelines. Available automatic contouring tools, including the 'interpolate' contouring function, may be utilized and contouring times will be recorded.
IGRT Assessment The patient will be set up on the breast board in treatment position. The 'ultra path' component of the Clarity system, which displays the path of the previous US acquired at CT simulation, will be used to guide the acquisition of US2. Although performed in the simulator room, the Clarity system will be used in 'treatment mode' thus simulating Clarity as it is used for IGRT. The study RT will first acquire the US2 scan. All steps following the acquisition of US2 will be performed off-line on the RM workstation without the need for further simulator or patient time.
