Angiography machine. This is the AXIOM Artis angiography machine, manufactured by Siemens. Angiography is a specialised form of radiography (X-ray), where a contrast medium is introduced to the circulation to make blood vessels opaque to X-rays. This machine combines radiography, angiography and fluoroscopy (an X-ray procedure that allows internal organs to be seen in motion). The C-arm (centre left) of this machine is moveable and flexible allowing it to be used during surgical procedures, in addition to diagnostic work. The X-rays or angiograms are displayed in real time on the screens at upper right.
