Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, flat panel CT or Digital Volume Tomography (DVT)) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone.
At a cost of US$600 to $3000, full-body scans are expensive, and are rarely covered by insurance. [10] [11] However, in December 2007, the IRS stated that full-body scans qualify as deductible medical expenses, without a doctor's referral. This will likely lead employer-sponsored, flexible-spending plans to make the cost of the scans eligible ...
The currently used low dose CT scan results in a radiation exposure of about 2 millisieverts (equal to roughly 20 two-view chest x-rays). [11] It has been estimated that radiation exposure from repeated screening studies could induce cancer formation in a small percentage of screened subjects, so this risk should be mitigated by a (relatively ...
In 2009, BBC News published a warning over private health scans, saying that private companies which provide screenings were often "expensive unnecessary and misleading." [ 7 ] The article also criticized the company for not warning people of any restrictions (such as false positives and false negatives ) and other disadvantages due to screening.
The extra cost of malpractice lawsuits is a proportion of health spending in both the U.S. (1.7% in 2002) [112] and Canada (0.27% in 2001 or $237 million). In Canada the total cost of settlements, legal fees, and insurance comes to $4 per person each year, [113] but in the United States it is over $16.

Components are 22. electron gun, 23. electron beam, 24. focus coil, 27. beam bending coil, 28-31. target rings, 14. detector array, 11. scan tube. The electron beam creates x-rays at the target rings, which radiates through the patient to the detector on the opposite end of the scan tube.
An estimated 72 million scans were performed in the United States in 2007, [30] accounting for close to half of the total per-capita dose rate from radiologic and nuclear medicine procedures. [228] Of the CT scans, six to eleven percent are done in children, [168] an increase of seven to eightfold from 1980. [167]
