TUBE WALL THICKNESS MEASUREMENT |
摘要 |
<p>24822 A method and apparatus for measuring the thickness of the wall of a tubular object includes a measurement of the intensity of a radiation beam passing through the walls and quantizing the indicated value of radiation detected by a detector with reference to a predetermined period of time. Data is expressed diagrammatically, and inflection points on the graph line indicating when the radiation beam contacts the outer and inner peripheral walls of the tube are determined and processed to thereby determine the wall thickness. There is also disclosed a method for aligning collimator members utilized in the radiation beam scanning equipment.</p> |
