Title:
ANGLE METER FOR RADIOGRAPHY
Document Type and Number:
Japanese Patent JP2023043215
Kind Code:
A
Abstract:
To solve the problem with a conventional angle meter configured so that a ball-like movable body that does not transmit an X-ray passes through a curved passage that a substantial material of the ball is limited to ceramics or metal from a viewpoint of durability since the ball involves a rolling movement, and if the ball is enlarged to enhance a discrimination performance, artifacts are generated.SOLUTION: An angle meter for radiography includes a container formed of an X-ray transmission material and an X-ray blocking agent put into the container. The container is formed with a scale of the X-ray blocking agent at a position corresponding to a horizontal plane that changes in the container if the container is tilted. The angle meter for radiography achieves high visibility and hardly causes artifacts.SELECTED DRAWING: Figure 1
