Rotational angiography is a medical imaging technique based on x-ray, that allows to acquire CT-like 3D volumes during hybrid surgery or during a catheter intervention using a fixed C-arm. The fixed C-arm thereby rotates around the patient and acquires a series of x-ray images that are then reconstructed through software algorithms into a 3D ...
Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, flat panel CT or Digital Volume Tomography (DVT)) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone.

Biderman's Chart of Coercion originated from Albert Biderman's study of Chinese psychological torture of American prisoners of war during the Korean War.. Biderman's Chart of Coercion, also called Biderman's Principles, is a table developed by sociologist Albert Biderman in 1957 to illustrate the methods of Chinese and Korean torture on American prisoners of war from the Korean War.
A mobile fluoroscopy unit generally consists of two units, the X-ray generator and image detector (II) on a moveable C-arm, and a separate workstation unit used to store and manipulate the images. [13] The patient is positioned between the two arms, typically on a radiolucent bed. Fixed systems may have a c-arm mounted to a ceiling gantry, with ...
With a C-arm system this can only be achieved by manually repositioning the C-arm for the second view. This can be challenging due to the presence of sterile drapes and other surgical devices. Bringing the x-ray generator from a non-sterile area , underneath the operating table to a horizontal position close do the patient can compromise the ...

Amsler grid, Chart 1 There are 7 types of Amsler grid charts. All charts measure 10 cm × 10 cm (3.9 in × 3.9 in), which when viewed at a distance of 33 cm (13 in) from the eye can be used to measure defects in the central 20 degrees of the visual field .
