Characterization of Radiolucent and Electro-Magnetic Properties of Polymer PEDOT: PSS for Radiological Applications

Abstract

The deployment of wireless technologies in the radiology field requires development of radiolucent materials allowing wireless communication. In this paper, both the radiolucency (X-rays) and ElectroMagnetic (EM) properties of the conductive polymer poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) are investigated to address wireless applications in the field of the radiology. A model was developed to predict the PEDOT:PSS performance and assess the interest of this material in terms of radiolucency characteristics and Electro Magnetic (EM) radiation efficiency. A PEDOT:PSS antenna operating in the Radio-Frequency Identification (RFID) Ultra High Frequency (UHF) band, was realized to experimentally validate abilities of PEDOT:PSS. These performances are compared with those produced by a similar antenna made of conventional materials such as copper. Experimental results validate the numerical model of the designed structure. This paper demonstrates the potential of polymer materials in the field of x-ray imaging.

The Acrylic Compensation Filter Design Enhances the X-Ray Image of the Ossa Manus in Posteroanterior Projection

“…Acrylic has a chemical formula (C5O2H8)n where the C, H, and O atoms in acrylic can absorb radiation that passes through it. X-rays that pass through acrylic, some of the radiation will be absorbed, and some will penetrate the bone and then forwarded to the film, eventually making the film black (formation of an image); this process is called radiolucency [9]. High energy will blacken the film image on body tissues that are exposed to X-ray radiation.…”
