Özet:

 


There are major shortcomings of phantoms, which are important for
improving the image quality of medical devices produced by developing
technology and also for calibration settings. The most important of these
shortcomings is the change in the concentration of the structures forming the
phantom and the deterioration of the structure due to external factors. It is
important to design and develop gel phantoms which are longer time resistant to
these negative effects and show electrical properties close to the living
tissue.  As is the case in many areas,
the use of live human subjects in the medical field has not been approved and
banned by many ethics committees due to the possibility of being harmful to
health, and instead of living human subjects, phantoms with close features are
used. In imaging systems, such as MR, Ultrasound, Tomography, X-ray, the
working range of these phantoms should be determined. In addition, the use of
mobile telephones has been widely used today, the absorption of electromagnetic
rays emitted from these devices (SAR) as a result of the loss of the electrical
property of phantom to determine the interval of distortion is important for
future advances and innovations in the medical field. 





In the study, 5 g PVA was heated in a beaker containing 45 ml of pure
water for 5 minutes at 80oC with stirring and a 10% buffer PVA
solution was prepared. Different amounts of Triton X-100 were added to these
buffer solutions and mixed for 15 minutes. After waiting for 24 hours,
dielectric constants of gel phantoms were examined at room temperature. Agilent
85070E Network Analyzer and Performance Probe with Short Block were used to
measure the dielectric constant. Gel phantoms were obtained showing the
dielectric properties of human breast tissue according to the measurements
taken in the frequency range 0 to 20 GHz. 10 ml 10% PVA + 5 ml Triton X-100 gel
phantom from this gel phantom was examined by changing the dielectric constant
by mixing 0.1 g SiC nanopowder. Afterwards, images of this gel phantom obtained
with WETSEM (Wet Scanning Electron Microscope) were examined.
