THE DEVELOPMENT OF A PORTABLE SCATTER RADIATION SHIELDING DEVICE FOR MOBILE X-RAY IMAGING

Abstract

This study had three main objectives: 1. To design and develop a portable scatter radiation shielding device for use with mobile X-ray units, 2. To evaluate the effectiveness of the device in reducing scatter radiation in various radiographic positions, and 3. To assess user satisfaction with the developed shielding device.

          This experimental study was conducted under controlled conditions using a prototype designed based on engineering principles and fabricated with 3D printing technology. The study was carried out in the radiographic area of the inpatient ward at Thamod Hospital. A phantom was used to simulate a real patient during imaging in standard radiographic positions, including chest AP (supine) and pelvis AP. A mobile X-ray unit (BMI JET 32 Plus) was employed, and scatter radiation was measured using a dosimeter positioned at a height of 120 centimeters from the floor, both before and after applying the shielding device. The phantom served as the sample for all measurements.

          Data collected from radiation measurements were analyzed using descriptive statistics, including mean and standard deviation, as well as the percentage reduction in scatter radiation to assess the effectiveness of the device. In addition, user satisfaction was evaluated using a questionnaire and analyzed descriptively.

          Results revealed that:

1. The development of the portable scatter radiation shielding device was successful. The device was lightweight, easy to transport, compatible with mobile X-ray units, and suitable for use in confined clinical spaces.


2. 2. The device effectively reduced scatter radiation, with average percentage reductions ranging from 5% to 99.5% at different positions around the phantom in the chest AP position.


3. 3. User satisfaction was rated at the highest level. From the satisfaction questionnaire (10 items), the average scores ranged from 70 to 5.00, indicating suitability in terms of usability, convenience, weight, and adaptability to inpatient ward environments.

          Importantly, the device demonstrated a statistically significant reduction in scatter radiation in all tested positions without interfering with the imaging procedure. Users reported the highest level of satisfaction (mean scores between 4.70 and 5.00), supporting the device’s feasibility for real-world clinical application and future development.
