C-ARM MACHIN

Vijaylaxmi Hospital & Research Center (VHRC) is very glad to introduce C-Arm . A C-arm is a medical imaging device that is based on X-ray technology and can
be used flexibly in various ORs within a clinic. The name is derived from the C-shaped
arm used to connect the X-ray source and X-ray detector to one another.

About C-Arm

Since the introduction of the first C-arm in 1955 the technology has advanced rapidly.
Today, mobile imaging systems are an essential part of everyday hospital life: Specialists
in fields such as surgery, orthopedics, traumatology, vascular surgery and cardiology
use C-arms for intraoperative imaging. The devices provide high-resolution
X-ray images in real time, thus allowing the physician to monitor progress at any point
during the operation and immediately make any corrections that may be required.
Consequently, the treatment results are better and patients recover more quickly.
Hospitals benefit from cost savings through fewer follow-up operations and from
minimized installation efforts.

A C-arm comprises a generator (X-ray source) and an image intensifier or flat-panel
detector. The C-shaped connecting element allows movement horizontally, vertically and
around the swivel axes, so that X-ray images of the patient can be produced from almost
any angle.
The generator emits X-rays that penetrate the patient’s body. The image intensifier or
detector converts the X-rays into a visible image that is displayed on the C-arm monitor.
The doctor can identify and check anatomical details on the image such as blood
vessels, bones, kidney stones and the position of implants and instruments at any time.

In the case of analog image intensifiers the X-ray strikes a
fluorescent surface after being attenuated to different
degrees through the patient’s body. Depending on the
strength of the radiation it causes the surface to glow more
or less brightly. Behind the surface is a vacuum tube, at the
end of which an analog camera captures the glow and
displays it on the monitor. Due to the curved surface of the
tube the accuracy of the image diminishes toward the
edges, leading to distortions.
