Abstract：Objective To study the human-computer interaction usability of linear digital radiography (DR) equipment based on
the usability concept of human-computer interaction research orientation. Methods The expert group of this project discussed and
determined the project indicators of usability evaluation, and established the usability evaluation model using Delphi method. By
users’ scoring five domestic DR models respectively, the usability evaluation results among user groups of different using time on
different models were compared. Results The mean total score and interface score of the 5 DR models showed significant differences
among the three groups (P<0.05). The score of the group with less than 3 months was significantly lower than the scores of the
other groups, while there was no significant difference between the other two groups (P>0.05). In addition, the usability evaluation
results of different DR models were significantly different in terms of the average total score and the group with more than 1 year.
Conclusion Usability evaluation can have a comprehensive view on the safety and effectiveness of DR man-machine interfaces,
which is helpful to the research and development of DR equipment and the improvement of domestic equipment.
