Description

One way to increase the contrast of the image in soft tissues is to use the k-edge subtraction imaging of the k-edge in soft tissues. In this method, the image can be captured by injecting a contrast agent into the tissue and recording two images, one before k-edge and one after the k-edge, and then logarithmic subtraction of two images. With this method a perfect contrast image can be obtained in soft tissue. X-ray tube or synchrotron radiation can be used to capture this image. Given that the synchrotron radiation is monochromatic, coherent and can also product X-rays with low energies, the images obtained from the k-edge subtraction imaging system using a synchrotron radiation have better contrast than the images with the use of X-rays from X-ray tube. In this paper, the k-edge subtraction imaging system was simulated in GATE and a phantom containing contrast agent was photographed using the X-ray from x-ray tube and synchrotron radiation. The results showed that the images obtained from the synchrotron radiation source have a better contrast.
