X-ray dosage in treatment and radiography
A 1922 technical manual on X-ray dosage and radiography by William Daniel Witherbee and John Remer, published by Macmillan in New York for physicians and radiographic technicians. Plates mix grainy halftone photographs of skin-test patches with hand-numbered squares, apparatus mounted on clamps and stands above draped patients, and small line diagrams of scalloped tube and field profiles.
