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]
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.
Flat-panel detectors are a class of solid-state x-ray digital radiography devices similar in principle to the image sensors used in digital photography and video. They are used in both projectional radiography and as an alternative to x-ray image intensifiers (IIs) in fluoroscopy equipment.
In 1999, Time placed Shoe-Store X Rays on a list of the 100 worst ideas of the 20th century. [29] [30] A shoe-fitting fluoroscope appeared on a 2011 episode of the History series American Restoration. [31] Its radionuclide source was found to be so dangerous that it was removed and replaced with a static X-ray. [32]
X-ray: uses X-rays to produce images of structures within the body; video link: Contrast media for X-rays: to provide a high contrast image of the details of the viscera under study; e.g. salts of heavy metals, gas like air, radio-opaque dyes, organic iodides, etc. Echocardiography machine: sonography of the heart is done here to know its ...
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.
Lead is the most common shield against X-rays because of its high density (11,340 kg/m 3), stopping power, ease of installation and low cost. The maximum range of a high-energy photon such as an X-ray in matter is infinite; at every point in the matter traversed by the photon, there is a probability of interaction.
The CTX 2500 utilizes a single rotating X-ray source to acquire positioning images and CT-slice images, thus achieving its smaller size. The CTX 2500 system is the first FAA-certified Explosives Detection System (EDS) mounted on a truck for easy mobility and access to cargo. One of the units costs approximately US$700,000.
