Effect of image sharpening on radiographic image quality.
Clark JL, et al. J Prosthet Dent 2018. PMID 30166247
The 3 sensors were again exposed without the phantom to determine the degree of radiographic noise. Each image was sharpened and then highly sharpened. ...Overshoot artifacts increased with image sharpening. CONCLUSIONS: Image sharpening improves visual image quality but significantly increases overshoot artifacts that adversely affect radiographic diagnosis. ...

Radiographic image enhancement. Part I: spatial domain techniques.
Analoui M. Dentomaxillofac Radiol 2001 - Review. PMID 11175266
This sequence of two articles will provide an overview of underlying concepts, along with algorithms commonly used for radiographic image enhancement. The first article focuses on spatial domain techniques for radiographic image enhancement, with particular reference to point processing methods, histogram modification and unsharp masking....

[Medical image enhancement: Sharpening].
Kats L and Vered M. Refuat Hapeh Vehashinayim (1993) 2015. PMID 26255429 Hebrew.
Most digital imaging systems provide opportunities for image enhancement operations. These are applied to improve the original image and to make the image more appealing visually. One possible means of enhancing digital radiographic image is sharpening. The purpose of sharpening filters is to improve image quality by removing noise or edge enhancement. ...

Radiographic digital image enhancement. Part II: transform domain techniques.
Analoui M. Dentomaxillofac Radiol 2001 - Review. PMID 11313724
Digital image enhancement techniques can have a significant impact on the diagnostic quality of a radiographic image. Selection of an image enhancement technique is a function of image content and its attributes of interest. ...In this second article on radiographic image enhancement the Fourier transform, the most commonly used transformation method, is used to examine examples of methods for image enhancement, with particular emphasis on the removal or reduction of noise....

Benchmarking the performance of fixed-image receptor digital radiographic systems part 1: a novel method for image quality analysis.
Lee KL, et al. Australas Phys Eng Sci Med 2016. PMID 27222198
This is the first part of a two-part study in benchmarking the performance of fixed digital radiographic general X-ray systems. ...A novel quantitative image quality analysis method is presented with technical considerations addressed for peer review. The novel method was applied to seven general radiographic systems with four different makes of radiographic image receptor (12 image receptors in total). ...

Image enhancement by spectral-error correction for dual-energy computed tomography.
Park KK, et al. Conf Proc IEEE Eng Med Biol Soc 2011. PMID 22256319
In this work, an image enhancement technique for DECT is proposed, based on the fact that the attenuation of a higher density material decreases more rapidly as X-ray energy increases. ...After analyzing the spectral-error sources of DECT images, we propose a DECT image enhancement method, which consists of three steps: water-reference offset correction, spectral-error correction, and anti-correlated noise reduction. ...

Digital mammography
Pisano ED and Yaffe MJ. Radiology 2005 - Review. PMID 15670993
In digital mammography, the processes of image acquisition, display, and storage are separated, which allows optimization of each. ...Once this information is recorded, it can be displayed by using computer image-processing techniques to allow arbitrary settings of image brightness and contrast, without the need for further exposure to the patient. ...

[Series: Practical Evaluation of Clinical Image Quality (3): Subjective Evaluation of Image Quality in Digital Radiography Systems].
Katayama R. Igaku Butsuri 2016. PMID 28428454 Japanese. Free article.
In the environment of picture archiving and communication system (PACS), the subjective evaluation of medical image quality is performed using an image display monitor. ...Moreover, image data interpolation to match the image matrix for the resolution of the monitor also alters the characteristics of images. ...

Digital radiography.
Harrison RM. Phys Med Biol 1988 - Review. PMID 3062645
Secondly, with all imaging systems there exists an inter-relationship between spatial resolution, image acquisition time, image noise and dose. ...Arnold (1982), in an overview of digital radiographic technology at that time, also noted the lack of standardisation of measurement techniques and exposure conditions, but nevertheless attempted a quantitative comparison of some aspects of digital radiographic systems with screen-film radiography and CT. ...
