Design the Direct X-ray Ruler, Don’t Let the Direct X-ray Ruler Design You

Abstract

Quality Assurance (QA) checks are important in ensuring medical equipment func tions properly. The complex and irregular environment the checks are carried out in places high utility and usability demands on QA products. In this project a design concept is developed for the next generation RaySafe DXR+, a QA tool for aligning an X-ray machine’s visual light with its radiation field. The focus of the design con cept is improving user experience and usability, specifically aimed at the Swedish market. A five phase iterative design process is described. The phases involve an ini tial user study, ideation and prototyping, a usability study, refinement of the design concept and validation. A list of requirements is developed alongside the concept. The result is a detailed design concept and an extensive list of requirements. Final evaluations indicate that the concept is a significant improvement and suits its QA task very well. Future work includes adapting the design to decrease production costs and evaluate it with international users.
