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]

[2] [1] Diagnosis is suspected based on symptoms and confirmed by X-rays or CT scanning. [1] If the bones remain normally aligned treatment may be by casting without weight bearing for around eight weeks. [1] If the bones are not properly aligned surgery is generally required. [1] Returning the bones to their normal position results in better ...
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.
X-ray of the foot of an 11-year-old child, showing sclerosis and fragmentation of the calcaneal apophysis. This is a sign of low sensitivity and specificity of Sever's disease, because those with Sever's disease may not have it, and this appearance is also present in feet without pain.

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 ...
Radiography uses X-rays to analyze the point of injury. This is not very effective at identifying soft tissue injuries. X-rays are created when high energy electrons hit a metal source. X-ray images are acquired by utilizing the different densities of the bone or tissue. When these rays pass through tissue they are captured on film.
