Proceedings of radiological health symposium
Resolution (or sharpness) of radiographic screen-film systems influences the physical image quality of radiographs, and thereby the diagnositc accuracy and patient exposure. We use the modulation transfer function (MTF) to quantify the resolution property of screen-film systems. In our laboratory, the slit method and the digital Fourier transformation are used for measurements of the MTFs of screen-film systems. Recent measurements indicate that the MTFs of Detail, Par Speed, and Hi-Plus screens with XRP film are significantly lower than the MTFs of the same screens with Blue Brand film. This result underscores the need to evaluate the resolution property of screen-film systems with close attention to the x-ray film used.
