Comparison of methods used to measure the characteristic curve of radiographic screen/film systems

Academic Article


  • A systematic study was performed to investigate the accuracy and precision attained by four methods for determining the characteristic curve of radiographic screen/film systems. The four methods include: inverse square sensitometry, KVP adjusted bootstrap sensitometry step-wedge bootstrap sensitometry, and step wedge attenuation sensitometry. The inverse square method was used as the reference standard for accuracy. The extent of and the sources of the inaccurcies involved when using the alternative methods is discussed. © 1980 SPIE.
