X-ray scanners use two different types of reconstruction of which one is Cone Beam reconstruction technology. Cone beaming adds size and cost to the technology but gets a needed image without the need of moving the patient in medical procedures. Cone beaming is not new and has been done in early CT scanning.
Cone beaming is needed in many instants such as when a patient is in critical condition and unable to be moved to obtain x-rays. The cost of cone beaming is beneficial in these cases but not always cost worthy. Cost factors may lead cone beam technology a thing for only certain uses but a good resource to have on hand in a crisis.
