A sonographer exists because ultrasound is the most operator-dependent imaging\nin medicine. A CT scanner produces the same slices no matter who pushes the\nbutton; an ultrasound image is created, frame by frame, by a human deciding where\nto put the probe, how to angle it, and how to tune the machine. The diagnosis\nlives or dies on those decisions. The radiologist reads the images but was not in\nthe room — they see only what the sonographer chose to capture. The discipline\nexists to make the interior of a living body legible in real time, without\nradiation, and to recognize the abnormal while the patient is still on the table\nand the scan can still be extended.
