METHOD FOR IDENTITY IDENTIFICATION AND/OR CAUSE OF DEATH DETERMINATION BASED ON DEAD BODY HEAD-NECK PROPERTIES Russian patent published in 2017 - IPC A61B6/03 

FIELD: medicine.

SUBSTANCE: dead body is scanned while it is in a sealed bag. Scan mode is continuous spiral. The following zones are explored sequentially: head - from the top to the C2 vertebra incluively, with maximum capture of head soft tissue volume; neck - from the top edge of the temporal bone to Th1 vertebra inclusively; ental - from the bottom edge of the lower jaw to the lower edge of the orbit; temporal bones - from the bottom edge of the mastoid process to the top of the temporal bone pyramid. To scan the "head" (H) zones, the following parameters are used: scan slice thickness - 0.9 mm, image viewer reconstruction slice thickness - 3 mm, kV - 120, mAs - 350, increment - 0.5, collimation - 64×0.625, pitch - 0.391, tube rotation speed - 0.5, matrix - 512×512, image field - 210. To scan the "neck" (N) zones: scan slice thickness - 1 mm, image viewer reconstruction slice thickness - 2 mm, kV - 120, mAs - 160, increment - 0.5, collimation - 64×0.625, pitch - 0.609, tube rotation speed - 0.75, matrix - 512×512, image field - 250. To scan the "dental" (D) zone: scan slice thickness - 0.67 mm, image viewer reconstruction slice thickness - 0.67 mm, kV - 120, mAs - 350, increment - 0.335, collimation - 20×0.625, pitch - 0.25, tube rotation speed - 0.4, matrix - 768×768, image field - 180. To scan the "temporal bones" (TB) zone, the following parameters are used: scan slice thickness - 0.67 mm, image viewer reconstruction slice thickness - 0.67 mm, kV - 120, mAs - 350, increment - 0.335 collimation - 20×0.625, pitch - 0.25, tube rotation speed - 0.4, matrix - 768x768, image field - 180. To view zone H images, the following modes are used: bone with C1500-W3000 window width, brain with C40-W80 window width; to view zone N images, the following modes are used: bone with C1500-W3000 window width, soft tissue with C60-W350 window width, pulmonary with C500-W1500 window width; to view zones D and TB images, the following modes are used: bone with C1500-W3000 window width, soft tissue with C60-W350 window width. The following is plotted: for zones H and N - multiplanar reconstructions - in sagittal and coronal planes and three-dimensional reconstructions, with coloured metal mapping, maximum and minimum intensity reconstructions. For zones D and TB - plotting of multiplanar reconstruction - in sagittal and coronal planes, reconstructions in a curved plane and three-dimensional reconstructions, with colour metal mapping, maximum intensity reconstructions. All the obtained results are used to identify the personality, the cause of death based on the corpse head-neck characteristics.

EFFECT: method ensures optimum scanning accuracy and accelerated research, including urgent, without a classical autopsy, with the exception of personnel infection risk.
