METHOD FOR DETERMINING HUMAN AGE FROM HAND X-RAY PICTURES USING PLANIMETRY Russian patent published in 2004 - IPC

FIELD: medicine.

SUBSTANCE: method involves measuring middle and distal phalanges base width on 2-5 fingers, proximal 1-2 finger phalanges canal widths and distal phalanges heads width on 2-5 fingers. Age is calculated from a formula AGE =-8.638+1.244R5+13.728 Q23, where AGE is the biological age in years, Q23 is the ratio the third finger distal phalanx body width to base width on the same hand, R5 is the not normalized head height of the proximal phalanx of the first finger.

EFFECT: high accuracy of the method.
