چکیده
The medical practitioner wishes a lung radiograph to be capable of revealing details uhich. are hardly perceptible. Jf he does not see a certain suspected detail does this then mean that that detail is non-existent, or is it that the X-ray picture is unable to reveal it? For a study of the general problem of perceptibility of details in X-ray technique good use -can be made of specially constructed phantoms.
