Imaging measurement by X-ray/gamma-ray

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...

Calibration of X-ray Imaging Devices for Accurate Intensity Measurement

Historically, X-ray imaging has been used to determine geometric and qualitative intensity information, such as tooth damage or star luminosity. For many endeavors, including astronomy, non-destructive testing, medicine, and plasma physics, the ability to measure accurately the X-ray intensity in a specific energy interval has become more important. But the metrology for these measurements, nam...

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...

Nanoscale X-ray imaging

NATURE PHOTONICS | VOL 4 | DECEMBER 2010 | www.nature.com/naturephotonics X-ray imaging at the nanoand microscale is of great interest for applications in the physical and life sciences. !e associated wavelength range1 extends from a few nanometres to a small fraction of a nanometre, o"ering the potential to image objects at this spatial resolution. !e concomitant photon energies of such wavele...
