What is the typical SID range described for these procedures in centimeters?

Source-to-image distance in mammography is typically about 65–66 cm. This relatively short distance keeps the compressed breast close to the detector, which helps minimize geometric magnification and maximize sharpness for small structures like microcalcifications. The other distances listed aren’t standard for mammography: 30–40 cm would magnify the image too much and restrict the field, while 100 cm or 120 cm belong to other imaging contexts and don’t align with the breast-imaging geometry and equipment design.
