A calcaneal spur (also known as a heel spur) is a bony outgrowth from the calcaneal tuberosity (heel bone). [1] Calcaneal spurs are typically detected by x-ray examination. [2] It is a form of exostosis. When a foot is exposed to constant stress, calcium deposits build up on the bottom of the heel bone. Generally, this has no effect on a person ...
Croup (/ k r uː p / KROOP), also known as croupy cough, is a type of respiratory infection that is usually caused by a virus. [2] The infection leads to swelling inside the trachea, which interferes with normal breathing and produces the classic symptoms of "barking/brassy" cough, inspiratory stridor and a hoarse voice. [2]

A radiograph of the head taken with the x-ray beam perpendicular to the patient's coronal plane with the x-ray source behind the head and the film cassette in front of the patient's face. [13] PA ceph can be evaluated by following analyses that have been developed through the years: Grummon analysis; MSR; Hewitt analysis; Svanholt-Solow analysis
The utility line worker from Arkansas lost his left eye, left eyelid, nose, lips and a large amount of facial tissue when his face grazed a 7,200-volt live wire in a horrific 2021 work accident.
The X-rays themselves are produced by the rapid deceleration of electrons in a target material, typically a tungsten alloy, which produces an X-ray spectrum via bremsstrahlung radiation. The shape and intensity of the beam produced by a linac may be modified or collimated by a variety of means.
An illustration of the heel effect in an x-ray tube. In X-ray tubes, the heel effect or, more precisely, the anode heel effect is a variation of the intensity of X-rays emitted by the anode depending on the direction of emission along the anode-cathode axis. X-rays emitted toward the anode are less intense than those emitted perpendicular to ...
The mask image is simply an image of the same area before the contrast is administered. The radiological equipment used to capture this is usually an X-ray image intensifier, which then keeps producing images of the same area at a set rate (1 to 7.5 frames per second). Each subsequent image gets the original "mask" image subtracted out.
