Exploring the potential of digital twin technology as a training tool for new radiographers

A digital twin is a virtual representation of the real world. This paper presents the concept of a digital twin system that reflects the movements of the human skeleton as the body is repositioned. Digital twin technology has the ability to be used as a training tool for new radiographers to build their competencies due to its ability to provide visual feedback without the use of radiation. This study aims to evaluate the perceptions of radiography trainers and trainees regarding the utility of digital twin technology.

The concept of digital twin technology was demonstrated to 46 trainers and trainees. Surveys were distributed online on the same day as the demonstration to gather feedback from the participants regarding the perceived usefulness of digital twin technology. For dichotomized and categorical variables, the relationships among these variables were examined using either the chi-squared test or Fisher's exact test. Inductive thematic analysis was used to analyze the open-ended questions.

Most respondents were willing to use digital twin technology (91.1 %) and agreed that it would be useful for education and training purposes (95.5 %). They also felt that it would improve radiographic skills (84.4 %) and confidence (93.3 %). Concerns regarding the product included its sensitivity to capturing subtle changes in positioning and its user-friendliness in terms of customization, and potential dependence on technology when positioning patients.

Digital twin technology has the potential to be a valuable training tool by allowing radiographers to hone their radiographic skills in a safe environment without the need for radiation exposure.
