G-arm medical imaging systems are based on fluoroscopic X-ray and are used for a variety of diagnostic imaging and minimally invasive surgical procedures.The name is derived from the G-shaped arm used to connect two X-ray generators and two X-ray detectors, image intensifiers or digital flat panel detectors, to one another.
The problem of radiation injuries due to fluoroscopy has been further addressed in review articles in 2000 [61] and 2010. [62] While deterministic radiation effects are a possibility, radiation burns are not typical in standard fluoroscopic procedures. Most procedures sufficiently long in duration to produce radiation burns are part of ...
The last can often be carried out in the operating theatre, using a portable fluoroscopy machine called a C-arm. [11] It can move around the surgery table and make digital images for the surgeon. Biplanar Fluoroscopy works the same as single plane fluoroscopy except displaying two planes at the same time.
"C-arm" mobile fluoroscopy machines are often colloquially referred to as image intensifiers (or IIs), [10] however strictly speaking the image intensifier is only one part of the machine (namely the detector). Fluoroscopy, using an X-ray machine with an image intensifier, has applications in many areas of medicine. Fluoroscopy allows live ...
[10] [11] Many fixed, and even mobile, C-arm fluoroscopy systems are now capable of CBCT acquisitions, in addition to traditional planar fluoroscopy. [12] [13] CBCT aids image guidance during interventional radiology procedures treating various medical conditions including knee osteoarthritis, benign prostatic hyperplasia, and hepatocellular ...
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 ...
Embolization is a process in which the interventional radiologist accesses the culprit bleeding vessel via a small catheter and interrupts blood flow to the site of bleeding via various mechanisms. Side effects of this procedure are minimal but there is a risk of bleeding and infection—though much less than the equivalent surgical procedure.
The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns.
