METHOD OF ABRASION AGE ESTIMATION IN INDIVIDUALS Russian patent published in 2010 - IPC A61B5/117 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to forensic medicine. The abrasion age estimation is ensured by distant measurement of maximum temperature of an abrasion and minimum temperature of an intact symmetric region, measurement of the abrasion area with specifying chronological age of an examined person. The face abrasion age is estimated by formula: AA_a = 92.917-33.219 ×(t_abr-t_symm) +1.251×S; while the trunk abrasion age is calculated by formula: AA_a = 98.125-34.344 ×(t_abr-t_symm) +1.932×S-0.169×A; the extremity abrasion age is shown by formula: AA_a=103.242-38.639 ×(t_abr-t_symm) +2.057×S-0.288×A; where AA_a is the estimated abrasion age, h; t_abr is temperature of an abrasion, °C; t_symm is temperature of an intact symmetric region, °C; S is the abrasion area, cm²; A is a victim's age, years. A true value of the face abrasion age (AA) is limited by formula: 9.979e^0.023AAa ≤ AA ≤27.119e^0.015AAa; the trunk abrasion age - by formula: 10.216e^0.022AAa ≤ AA ≤28.333e^0.0145AAa; the extremity abrasion age - by formula: 10.894e^0.021AAa ≤ AA ≤29.092e^0.0142AAa; where AAa is the estimated abrasion age, h; AA is the true abrasion age, h.

EFFECT: method allows noncontact high-accuracy abrasion age estimation in individuals.
