Simulation study of radiographic image quality measurement based on transmitted information



Simulation study of radiographic image quality measurement based on transmitted information



Nihon Hoshasen Gijutsu Gakkai Zasshi 63(3): 341-344



Although radiographic image quality is considered difficult to evaluate in a straightforward and systematic manner, it may be possible by using an index of transmitted information. As a preliminary study, relations between transmitted information and two image characteristics, namely, image noise and image blurring, were evaluated by simulation. The value of transmitted information was decreased if image noise and image blurring increased. The relationships were corroborated on an experimental basis. This paper suggests the possibility of a simple, straightforward method for synthetically evaluating radiographic images by a single parameter in terms of transmitted information.
