The use of the new application for non-radiologists speeds up and simplifies demonstration of radiologic images in daily clinical routine.

Integrated imaging viewers in electronic health care records (EHR) are mostly too complicated and too slow for daily clinical work on the ward. Therefore, we developed a new application based on: (i) a virtual model of the human anatomy for an intuitive and simple visualization and (ii) web technologies for an easy access.

The new application includes a 3D-model of human anatomy for visualization and was compared with a commercially available integrated dicom-viewer (impax) into our HER-system on 10 common tasks of daily clinical routine. The tasks consisted of finding, displaying and comparing radiologic image series. 5 physicians without experience in neither of the applications (5 male,mean 30.4y;range 26-41y)were included in the evaluation. The time to execute each task was measured and recorded for each of the applications. A standard software usability survey(SUS) was further conducted to evaluate the ease of use and measure the qualitative fit of the new approach in a ward. The new application significantly (p=0.003) reduced the time needed to find and display radiologic image series (mean:43.56sec;SD±17.41sec) compared to a standard dicom-viewer (63.17sec;SD±26.76sec). Additive use of basic functions (e.g. locating/measuring anatomic structures in CT) was slightly but non-significantly improved (96.95 vs. 100.52 sec). Evaluation of the SUS-forms revealed a significantly (p<0.001) higher usability score for the new application (mean:3.98/5;SD±1.11) compared to the standard software (mean: 2.76/5;SD±1.37). Statistics were calculated using paired student`s t-test and Wilcoxon-rank test.  

The use of intuitive visualization based on human anatomy significantly speeds up demonstration of radiologic image series in daily clinical routine procedures compared to standard text based dicom-viewers. Additively our new application shows a significantly higher usability score due to its intuitive simplicity. The intuitive user interface and the possibility to automatically display matching 3D-anatomy further increase the practicability.
