Morphology
B-scan + ultrasonography
Ultrasonography clearly signals imaging using ultrasound, and the element 'B-scan' transparently includes 'scan' with a letter label indicating a particular mode or type of scan, so a learner who knows the constituents can infer this is a specific kind of ultrasound examination. However, the precise technical sense of 'B-scan' (its exact imaging mode and the specific anatomical focus) is specialized and not fully predictable from the parts alone, so detailed meaning would require prior exposure.
Etymology
B-scan ultrasonography gets its name from the kind of picture the machine makes: B stands for 'brightness' because the scan shows bright lines, and scan means moving a sound beam across the eye to make a slice picture. So the phrase now means using ultrasound to make a picture of the back of the eye.
