The CTX (Computer Tomography X-ray) is an explosive detection device, a family of x-ray devices developed by InVision Technologies in 1990 that uses CAT scans and sophisticated image processing software to automatically screen checked baggage for explosives.
The Nokia 9 PureView is a Nokia-branded flagship penta-camera smartphone developed by HMD Global. It was introduced at the 2019 Mobile World Congress (MWC) in Barcelona, Spain as a successor to the Nokia 8 Sirocco. It alludes to Nokia's previous camera-centric PureView devices, which ended with the Lumia 950 and 950 XL.
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.
Millimeter wave scanners should not be confused with backscatter X-ray scanners, a completely different technology used for similar purposes at airports. X-rays are ionizing radiation, more energetic than millimeter waves by more than five orders of magnitude, and raise concerns about possible mutagenic potential.
The Nokia 808 PureView features a 41 MP 1/1.2 in (10.67 × 8 mm) sensor and a high-resolution f/2.4 Zeiss all-aspherical 1-group lens. The 808's sensor was the largest (over 4 times larger than typical compact cameras ) sensor ever to be used in a cameraphone at the time of its launch, a record previously held by Nokia's N8 [ 6 ] and, as of ...
Electron beam computed tomography (EBCT) is a fifth generation computed tomography (CT) scanner in which the X-ray tube is not mechanically spun in order to rotate the source of X-ray photons. This different design was explicitly developed to better image heart structures that never stop moving, performing a complete cycle of movement with each ...
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.
Full body scanner in millimeter wave scanners technique at Cologne Bonn Airport Image from an active millimeter wave body scanner. A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact.
