[Effectiveness of a positioning doll for radiography: through performance as a practice of radiography training and a questionnaire targeted for radiological technologists].

The effectiveness of a positioning doll for radiography training (XPD) and acquiring the techniques of radiography was evaluated through performing radiography practice for the students in our school of radiological technologists and a questionnaire for radiological technologists. We made a ranking test composed of a five-grade evaluation system of the 39 students for the techniques of radiography before and after the practice, and questionnaires about the XPD were given to the same students after the practice. The questionnaires about affinities between human bodies and the XPD and effectiveness of the XPD for the education of students were also carried out in six radiological technologists to examine the effectiveness of the practice of radiography by using the XPD. The rankings of the students after the practice were significantly higher than those before the practice (p <0.01), and 85% of the students rated the practice using the XPD as useful for them in acquiring the techniques of radiography. Seventy-eight percent of the radiological technologists rated it useful for student education in radiography. In conclusion, it was suggested that practice using the XPD was effective in helping students to acquire the techniques of radiography. We would like to develop supplementary tools for fixing the XPD and using the practice of radiography in many ways and in new directions in the future.
