title: [Method of x-ray osteophotometry of the lumbar region of the spinal column].
abstract: The content of mineral salts in all diseases of the skeleton has greater or less deviations from the norm. The change of the mineral content can be visually determined in routine roentgenograms when the deviation is not less than 20-30% from normal. This estimation has a great share of subjectivism. The optical density of the bone in roentgenogram objectively shows the content of calcium salts and its structure. Under study was the influence of soft tissues surrounding the lumbar part of the vertebral column upon the optical density index. Ten preparations of lumbar divisions by means of the aluminium wedge.
