Digital cineradiography is used during cardiac catheterization procedures. It consists of three main components: 1) an automatic brightness control that adjusts exposure based on tissue density, 2) a beam-splitting mirror that directs images to a monitor and cine camera simultaneously, and 3) a cine camera that films the angiographic images but increases patient radiation dose. During cardiac catheterization, a catheter is inserted and contrast dye is used to create X-ray videos of the heart valves, arteries, and chambers at various frame rates to diagnose and treat cardiovascular conditions.

1. Digital
Cineradiography

2. Component of
cineangiographic
1. automatic brightness control
2. beam-splitting mirror
3. cine camera

3. DEFINATION
1. automatic brightness control (ABC) is
compensates the beam quality/quantity for differences in anatomic
thickness or density by adjusting kVp, mA, or both
2. a beam-splitting mirror
permits simultaneous filming and viewing of the images during the
procedure; directs 10% of image to monitor and 90% of image to
cine camera
3. the cine-camera
resembles a movie camera- allowed for the filming of
cineangiographic images but increase the patience dose

4. when is digital cineradiography used?
• cardiac catheterization
• a procedure used to diagnose and treat cardiovascular conditions.
• procedure that allows your doctor to "see" how well your heart is
supplied by blood vessels
• During cardiac catheterization, a long thin tube called a catheter is
inserted in an artery or vein in your groin, neck or arm and threaded
through your blood vessels to your heart.
• Contrast dye is injected through the catheter so that X-ray videos of
your valves, coronary arteries, and heart chambers can be created.
• taking numerous exposures, known as frames, in second of time.
• typically, cardiac catheterization involves exposure rates of 15,30, or
60 frames per second.
