title: [The measurement of linear dimensions from the x-ray image on a video monitor].
abstract: The proposed method for measuring the linear dimensions of viscera from their X-ray image on a video monitor is that a uniform X-ray contrast is placed on a recording screen, which fixes the image of a point object (for example, a catheter tip) which is situated in the plane of the required size. The patient is transferred in parallel with the screen at a given distance. Before and after transfer, a ratio of the scale change in the position of a point object image to its actual change is calculated. The ratio is used to measure any linear dimensions in the plane of an object.
