2.B X-Ray Imaging with Kirkpatrick-Baez Microscopes

This article describes the design, testing, and use of Kirkpatrick-Baez (KB) x-ray microscopes on OMEGA. These microscopes consist of grazingincidence mirror pairs arranged to reflect and focus x rays, thereby providing images of the x-ray-emitting region. KB microscopes are one of several practical devices that can be used to focus and collect x rays. Simpler x-ray-imaging devices are the pinh...

Evaluation of multifunctional targeted gold nanoparticles on X-ray attenuation in nasopharyngeal cancer cells by X- ray imaging

Introduction: Head-and-neck cancer is the sixth most common cancer worldwide with the number of cases consistently increasing in developing countries. Successful development of effective, safe and cost effective nanoprobes for head-and-neck cancer targeting imaging is a big challenge. This study is aimed to develop cysteamine-folate conjugated gold nanoparticles (F-Cys-AuNPs) a...

X-ray imaging physics for nuclear medicine technologists. Part 2: X-ray interactions and image formation.

The purpose is to review in a 4-part series: (i) the basic principles of x-ray production, (ii) x-ray interactions and data capture/conversion, (iii) acquisition/creation of the CT image, and (iv) operational details of a modern multislice CT scanner integrated with a PET scanner. In part 1, the production and characteristics of x-rays were reviewed. In this article, the principles of x-ray int...

Digital X-Ray Imaging

The use of X-ray image receptors that produce a digital image is becoming increasingly important. Possible benefits include improved dynamic range and detective quantum efficiency, improved detectability for objects of low intrinsic contrast, and reduced radiation dose. The image can be available quickly. The display is separated from the image capture so that processing and contrast adjustment...
