What Are C-Arms?
C-arms are one of the driving technological forces behind the advancement of minimally invasive surgeries. These mobile fluoroscopic imaging systems are precise and accurate devices that allow for less patient discomfort in a variety of surgical and nonsurgical procedures. The minimal invasiveness with the use of C-arms has helped lead to the increase of more cost-effective outpatient care. C-arms provide patients with minimally invasive, pain-reduced procedures.
Initially used in general surgery or orthopedic applications, C-arms are now described by both manufacturers and users as highly versatile, thanks to the technological advancements made since the original designs.
In fact, C-arm usage recently has expanded to include minimally invasive, spinal, general, and orthopedic surgeries; pain management; and cardiac, urology, vascular, and neurovascular applications.
An X-ray image intensifier (XRII), sometimes called a C-Arm, refers to a special image intensifier device used in medical imaging involving x rays. It consists of an input window, input phosphor, photocathode, vacuum and electron optics, output phosphor and output window.
It allows for lower x-ray doses to be used on patients by magnifying the intensity produced in the output image, enabling the viewer to easily see the structure of the object being imaged. C-Arms were introduced by Philips in 1955.
An image intensifier or II is used in two ways:
1. As a Fixed piece of equipment in a dedicated screening room
2. Mobile Equipment for use in theatre
Fixed Image Intensifiers
These are used in most xray departments as 'screening rooms'. The types of investigations for which this machine can be used for is vast. Examples include:
Barium Studies (Swallows, Meals, Enemas)
Endoscopy Studies (ERCP)
Fertility Studies (HSG)
Angiography Studies (Peripheral, Central and Cerebral)
Thereaputic Studies (Line placements i.e. Permacath / Hickman, Transjugular Biopsies, TIPS Stent, Embolisations)
Cardiac Studies (PTCA)
Mobile Image Intensifiers (MII)
Smaller in design than a fixed image intensifier, mobile screening units are becomming more and more powerful. This has enabled more advanced and technical procedures to be carried out in confined locations. MII's are routinely used in most hospitals for:
Orthopaedic Imaging in theatre
(DHS, ORIF's and MUA's)
Neurolgical Imaging in theatre
Endovascular Imaging in theatre (EVAR)
Therapeutic Procedures in theatre (pain clinic)
Image intensifiers are usually set up for two purposes. For either plain fluoroscopy or digital subtraction angiography (DSA). All image intensifiers are set up with software capable of adjusting settings to suit different user requirements, depending on the procedure and body area being imaged. In simple flouroscopy for example, imaging of the throat would not require the same amount of exposure as that of the abdomen. And on DSA capable models, preset programs are available which enables the user to decide a rate of how many images or frames per second are acquired.
