Innovative radiographic system to improve the sharpness of radiographs: could a phase-shift effect contribute to improved image-quality for plain computed radiographs for general use?

Abstract

This technique may be suitable for clinical use and may contribute to improved image-quality in general radiography.

Preliminary results of a study comparing conventional radiography with phase-contrast radiography for assessing root morphology of mandibular third molars

“…5 We have previously shown that an image of the hand of a patient with rheumatoid arthritis was more clearly depicted when obtained on PCR than on conventional radiography because of the higher spatial resolution of the former. 6 The Talbot-Lau-type method, which is a phase-contrast technology, is normal for practical use. 14 This method does not need a special X-ray tube; however, it is essential to use special grating to obtain images.…”

“…4 Moreover, we and other investigators have previously demonstrated that phase-contrast images can depict hard tissues such as micro-calcification associated with breast cancer or trabeculae associated with the hand. [5][6][7] To our knowledge, whether this new method is useful for assessing mandibular third molars has not previously been examined.…”
