A region of interest (ROI) is a user-specified area in an image (Figure 5.1). The ROI tools
enable you to create three types of ROIs: measurement, average background, or subject
ROI (Table 5.1). During a session, the Living Image ® software records information about
the ROIs you create and computes statistical data for the ROI measurements. The ROI
Measurements table displays the data and provides a convenient way to review or export
ROI information (Figure 5.1). (For more details, see Managing the ROI Measurements
Table, page 91.)
