Which control can a sonographer apply to help delineate a subtle liver mass?

Edge enhancement
Fill-in interpolation
Increase the receiver gain
Zoom

The correct answer is: Edge enhancement

Edge enhancement is the correct answer because it can help improve the visibility of subtle boundaries or edges of a liver mass, making it easier to differentiate from the surrounding tissue. This technique enhances the sharpness of edges in the ultrasound image, which can be particularly useful when trying to identify subtle abnormalities. Options B, C, and D are not directly related to improving the visualization of subtle structures within the liver. Fill-in interpolation is a method used to fill in missing data in an image to improve image quality, increasing the receiver gain can improve overall brightness but may not specifically help with delineating a subtle liver mass, and zooming may only magnify the image without enhancing specific details like edges of a mass.
