In radiology, the thumbprint sign, or thumbprinting, is a radiologic sign found on a radiograph that suggests the diagnosis of either epiglottitis or intestinal ischemia.. In a lateral C-spine radiograph, the sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.
EOS is a medical imaging system designed to provide frontal and lateral radiography images, while limiting the X-ray dose absorbed by the patient in a sitting or standing position. The system relies on the high sensitivity of a detector ( multi-wire chamber ) invented by Georges Charpak , which earned him the 1992 Nobel prize .
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 ...

This is the most basic form of conventional tomography. The X-ray tube moved from point "A" to point "B" above the patient, while the detector (such as cassette holder or "bucky") moves simultaneously under the patient from point "B" to point "A". [5] The fulcrum, or pivot point, is set to the area of interest. In this manner, the points above ...
