Abstract

Introduction

We have conducted a prospective study to clinically evaluate a new radiation dose observing tool that displays patient’s peak skin dose (PSD) map in real time.

Methods

The skin dose map (SDM) prototype quantifies the air kerma based on exposure parameters from the X-ray system. The accuracy of this prototype was evaluated with radiochromic films, which were used as a mean for PSD measurement.

Results

The SDM is a reliable tool that provides an accurate PSD estimation and location.

Conclusion

SDM also has many advantages over the radiochromic films, such as real-time dose evaluation and easy access to critical operational parameters for physicians and technicians.
