Quality of 'commercial-off-the-shelf' (COTS) monitors displaying dental radiographs.

Background: A computer display monitor used for interpreting dental images should have a maximum luminance of 171 cd/m(2). A monitor used for clinical review should have a maximum luminance of 100 cd/m(2).

Objective: To compare luminance and ambient lighting measurements for a selection of computer display monitors in different locations of a dental teaching hospital to available guidelines.

Could standardizing "commercial off-the-shelf" (COTS) monitors to the DICOM part 14: GSDF improve the presentation of dental images? A visual grading characteristics analysis.

Objectives: To investigate whether standardizing commercial off-the-shelf (COTS) display devices to the digital imaging and communications in medicine part 14: greyscale standard display function (DICOM part 14: GSDF) would affect the presentation of dental images.

Methods: Two COTS display devices from the radiology department of a dental teaching hospital and a laptop computer monitor for reference were calibrated to conform to DICOM part 14: GSDF. Four dental surgeons and two final-year students undertook a relative visual grading analysis of the two devices before and after calibration, under control of the viewing environment.

A comparison of the accuracy of film-screen mammography, full-field digital mammography, and digital breast tomosynthesis.

Aim: To measure the change in diagnostic accuracy of conventional film-screen mammography and full-field digital mammography (FFDM) with the addition of digital breast tomosynthesis (DBT) in women recalled for assessment following routine screening.

Materials And Methods: Ethics approval for the study was granted. Women recalled for assessment following routine screening with screen-film mammography were invited to participate.

Evaluation of a software package for automated quality assessment of contrast detail images--comparison with subjective visual assessment.

Contrast detail analysis is commonly used to assess image quality (IQ) associated with diagnostic imaging systems. Applications include routine assessment of equipment performance and optimization studies. Most frequently, the evaluation of contrast detail images involves human observers visually detecting the threshold contrast detail combinations in the image.
