Title:
METHOD FOR MEASURING VARIOUS DENSITIES OF OSSEIN AND X-RAY FILM BODY AS WELL AS SHEET BODY WITH METALLIC PIECE FOR REFERENCE, AND X-RAY PHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JP2719089
Kind Code:
B2
Abstract:
PURPOSE: To prepare the X-ray film body adequate for use in a method for measuring the various densities of the ossein in by comparing the density of the ossein with the degree of blackening of titanium metals, the sheet body with metallic pieces for reference for the reference of the degree of blackening of an X-ray film image adequate for use which can be easily used in combination at the time of X-ray photographing and to provide the X-ray photographing device.
CONSTITUTION: The titanium metal is simultaneously photographed at the time of X-ray photographing and the various densities of the ossein is measured by vomparing the degree of blackening of the titanium metal and the degree of blackening of the ossein. For example, six kinds of titanium pieces 3 of 0.3 to 1.3mm thickness are stuck to transparent backing paper 2 and the sheet body 1 with the metallic pieces for reference are stuck to the X-ray film body and is photographed. The titanium pieces are simultaneously photographed. The degrees of blackening transmitted through the titanium and through the ossein are numerically read by a degree of blackening measured by a blackening measuring instrument by the film photographed. The comparison of the degrees of blackening is easy.
