Abstract:
One of the most important points in the whole process in digital radiology is to have high quality displays due to deteriorate any information received data acquisition and image processing phases. Nowadays the common display device in observing medical imaging is medical grade TFT LCD monitor. In diagnostic radiology, medical monitors are mainly recommended because of their higher luminance and better contrast ratio. However; the remarkable problem with medical grade monitors is its high cost. In order to nd the solution for decreasing the cost; in this study we want to evaluate the clinician's performance of the other display devices such as large screen TV and tablet for observing the medical imaging. Another objective is to evaluate the potential of tablet as Teratological tool for assessing chest X-ray images with nodule. In this experiment, the data set consisting of 60 chest radiographs were assessed by three experienced radiologists. The area under curve (AUC) of each ROC curve was used as a metric for detecting lung modules in the radiographs. AUC for medical monitor for viewer 1, 2 and 3 were calculated as 0.634, 0.703 and 0.755 respectively. AUC for Tablet for observer 1, 2 and 3 were calculated as 0.634, 0.703 and 0.755 respectively. AUC for large screen TV for radiologist 1, 2 and 3 were calculated as 0.634, 0.703 and 0.755 respectively. According to Analysis of variance or ANOVA test with 95 % con dence interval, there is statistically not signi cant di erences between Medical monitor, tablet, and Large screen TV. Consequently, it is possible to implement Tablet and large screen TV as a medical monitor for medical diagnosis purposes without sacri cing any diagnostic value.|Keywords : Digital Radiology,ROC curve, ANOVA, AUC, Teleradiology.
