## OUTLINING THE TOTAL BREAST AREA

Suggestion: Outline the total breast area in a separate session (See Suggested Procedures).

Switch to Bias & Gain mode using the Image->Enhancement sliders menu or by clicking on the icons above the contrast & brightness sliders. Use the Bias & Gain sliders to achieve the best definition of the perimeter of the entire breast. Trace a region of interest which corresponds to the perimeter.
