The study aims to evaluate the pressure redistribution capabilities of both new and older X-ray table mattresses. Researchers used 21 different 2.5 cm-thick mattresses and an anthropomorphic human phantom with varying weights to simulate areas of the body that are most susceptible to pressure ulcers (head, pelvis, and heels). The peak pressure and Interface Pressure Ratio (IPR) were measured using Xsensor technology.

Results showed that all mattresses made a statistically significant difference in peak pressure and IPR values when compared to not using a mattress at all. 

Older mattresses performed worse than newer ones in both peak pressure and IPR values.

The study concludes that using newer mattresses significantly reduces peak pressure and IPR, possibly due to better materials used in their construction or because older mattresses lose their pressure-distributing abilities over time. The paper suggests that radiology departments should consider regular assessments of their mattresses' pressure redistribution properties.
