ROI stands for Region of Interest. In X-ray inspection and image processing, it refers to a specific portion of an image selected for detailed analysis or processing.
By defining an ROI, operators can isolate critical features--such as solder joints, voids, or internal components--while excluding irrelevant background data. This approach allows for more efficient data processing, faster calculation times for automated inspections, and improved contrast or filtering applied specifically to the target area.
