SCATTER RADIATION

Testing Summary

 

STARTable

Background

Adept Medical STARTable Shield is embedded with 0.5mm Lead (Pb), offering protection from scatter radiation for operators. To verify this, testing was carried out to measure the product’s effectiveness in a controlled environment, by simulating scatter radiation exposure to operators and measuring x-ray dose around a gridded pattern.

The testing was conducted at Auckland District Health Board Interventional Cardiology Laboratory’s on a Siemens Artis Imaging Table. The measurements were recorded by Brian Lunt, Medical Physicist. A radiographic human torso phantom was used to simulate a patient on the table and provides the primary source of radiation to the clinician and staff via scatter. 

Results

At gantry tilt 0°

  • The maximum percentage scatter radiation reduction throughout the grid is 90%.

  • At 110 cm (waist height – 4D correlating to usual clinician position during procedure), the scatter radiation reduction with use of Adept Medical STARTable is 77%.

  • At 150 cm (neck height – 6D correlating to usual clinician position during procedure), the scatter radiation reduction with use of Adept Medical STARTable is 65%.

  • At the cranial end of the STARTable, the scatter radiation reduction is negligible.

  • At the caudal end of the STARTable, the scatter radiation reduction is 79%.

At LAO 34°/CRAN 20° 

  • The maximum percentage scatter radiation reduction throughout the grid is 89%.
