C-arm cone-beam CT: general principles and technical considerations for use in interventional radiology

J Vasc Interv Radiol. 2008 Jun;19(6):814-20. doi: 10.1016/j.jvir.2008.02.002. Epub 2008 Apr 23.


Digital flat-panel detector cone-beam computed tomography (CBCT) has recently been adapted for use with C-arm systems. This configuration provides projection radiography, fluoroscopy, digital subtraction angiography, and volumetric computed tomography (CT) capabilities in a single patient setup, within the interventional suite. Such capabilities allow the interventionalist to perform intraprocedural volumetric imaging without the need for patient transportation. Proper use of this new technology requires an understanding of both its capabilities and limitations. This article provides an overview of C-arm CBCT with particular attention to trade-offs between C-arm CBCT systems and conventional multi-detector CT.
