An x-ray image receptor, containing an anti-scatter grid and three AEC regions (represented by dark grey circles and square) These regions represent anatomical areas, e.g. lungs, spine. They can be selected individually, or all at once depending on the need. Automatic Exposure Control (AEC) is an X-ray exposure termination
Fish bone pierced in the upper esophagus. Right image without contrast medium, left image during swallowing with contrast medium. To obtain an image with any type of image detector the part of the patient to be X-rayed is placed between the X-ray source and the image receptor to produce a shadow of the internal structure of that particular part of the body.
The eXaminer 3DX 6000 explosive detection system developed by L-3 operates similarly to the CTX system. In 2013 Rapiscan Systems made the first delivery of its RTT product. [2] This machine operates with a non-rotating 360 degree multi source X-ray tube and detector array CT imaging system so the only moving part is the conveyor belt.
An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
Xeroradiography is a type of X-ray imaging in which a picture of the body is recorded on paper rather than on film. In this technique, a plate of selenium, which rests on a thin layer of aluminium oxide, is charged uniformly by passing it in front of a scorotron. [1] The process was developed by engineer Dr. Robert C. McMaster in 1950. [2]
manual MoM: Antenna modeling, especially in Amateur Radio. Widely used as the basis for many GUI-based programs on many platforms. Version 2 is open source, but Versions 3 and 4 are commercially licensed. Momentum: commercial Yes Yes Partial Yes Yes equidistant MoM
X-Ray systems that use methods such as laminography ( or the now more commonly used tomography ) are marketed as “3D” x-ray systems. X-Ray systems that do not use these methods and only produce a transmissive shadow image are marketed as “2D” systems. The 5DX used a gantry robot to move the assembled printed circuit board underneath an ...
Digital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette. [1]
