“…Krupinski et al reported on display parameters such as the influence of monitor luminance and tone scale regarding observer detection [18,19]. In their study, the authors used mammograms for viewing medical images by adjusting the monitor's maximum luminance to 275 cd/m 2 and 480 cd/m 2 .…”

The aim of the present study was to propose suitable display functions for CT image representation on liquid crystal display (LCD) monitors by analyzing the characteristics of the monitor's typical display functions using psychophysical analysis. The luminance of the LCD monitor was adjusted to a maximum of 275 cd/m2 and 480 cd/m2. Three types of postcalibrated display functions (i.e., GSDF, CIELAB, and Exponential gamma 2.2) were evaluated. Luminance calculation of a new grayscale test pattern (NGTP) was done for the conversion of the digital driving level (DDL) into the CT value. The psychophysical gradient delta of display functions for the CT value was evaluated and compared via statistical analysis. The delta value of GSDF and CIE decreased exponentially; however, the delta value of Exponential gamma 2.2 showed a convex curve with a peak at a specific point. There was a statistically significant difference among the delta values of the three types of display functions on the 480 cd/m2 maximum via Kruskal Wallis test (P<0.001). The GSDF was suitable for observation of abdominal and lung CT images; however, the display function combined the Exponential gamma 2.2 and the GSDF functions and was ideal for observation of brain CT images by psychophysical analysis.

“…Nei monitor Barco come L max viene impostato un valore corrispondente a quello dichiarato dalla casa costruttrice come valore "calibrato"; tale luminanza è inferiore alla luminanza massima che il monitor è in grado di emettere, in modo che sia possibile nel tempo mantenere la luminanza calibrata nonostante l'inevitabile decadimento dovuto all'uso [11]. I monitor EI-ZO invece, per poter rispettare i limiti minimi di luminanza richiesti vanno impostati alla massima luminanza possibile (brightness=100% nella maggioranza dei casi), rendendo così impossibile compensare il deterioramento che viene inoltre accelerato dagli alti valori di brightness impostati.…”

“…An important way to achieve this is by examining how radiologists actually go about the interpretation of images by conducting eye tracking studies. Past studies that have used eye tracking to analyze conventional radiography have covered extensive research topics, such as radiologists' reading strategy, [1][2][3][4][5][6] perceptual and cognitive processes during the interpretative process, [7][8][9][10][11][12][13][14] differences in gaze patterns of experts and novices and how expert visual search could be trained, [15][16][17][18][19] display properties that are associated with superior performance, [20][21][22] the comparison of visual processes when satisfaction of search occurred, 23,24 gaze characteristics that are linked to different decision outcomes 25,26 and how these could be used to provide perceptually based feedback, [27][28][29][30][31][32][33][34] or how lesion properties influence radiologists' perception and decision making processes. [35][36][37][38][39] A number of studies have even looked at how eye tracking studies need to be conducted to yield the most valid results.…”

Abstract. While eye tracking research in conventional radiography has flourished over the past decades, the number of eye tracking studies that looked at multislice images lags behind. A possible reason for the lack of studies in this area might be that the eye tracking methodology used in the context of conventional radiography cannot be applied one-on-one to volumetric imaging material. Challenges associated with eye tracking in volumetric imaging are particularly associated with the selection of stimulus material, the detection of events in the eye tracking data, the calculation of meaningful eye tracking parameters, and the reporting of abnormalities. However, all of these challenges can be addressed in the design of the experiment. If this is done, eye tracking studies using volumetric imaging material offer almost unlimited opportunity for perception research and are highly relevant as the number of volumetric images that are acquired and interpreted is rising.
