Abstract:
Streak cameras are powerful tools that provide high temporal resolution by capturing one-dimensional images with slitted photocathodes while sacrificing the two-dimensional spatial information. A two-dimensional imaging enabled x-ray streak camera system has been developed to acquire the two-dimensional images in situ, with 27 μm spatial resolution and 150 ps time resolution. By attaching a scintillator plate in front of the cathode, x-ray emissions beyond the cathode slit are converted into visible light and recorded by an imaging camera. The simultaneous measurement of one-dimensional time-resolved and two-dimensional time-integrated images in the laser fusion experiment has demonstrated the benefits of the endoscope. Such a system could greatly extend the uses of traditional x-ray streak cameras.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
