The accordion sign at CT: a nonspecific finding in patients with colonic edema.

abstract：:A clinical comparison study of scanning equalization radiography (SER) and conventional chest radiography was performed with the latest prototype SER system. Conventional chest radiography was performed at 120 kVp with Lanex regular screens (Eastman Kodak, Rochester, NY) and Kodak Ortho-G or Ortho-C film (Eastman Koda...

abstract：:The Wiener spectra of five screen-film systems were studied as a function of monoenergetic x-ray energy. These spectra, in their low-frequency limits, were seen to depend linearly on x-ray energy. The Wiener spectra also decreased in magnitude as the incident x-ray energy exceeded that of the screen phosphor K absorpt...
