Computed tomography is one of the workhorses of clinical imaging. Unfortunately, its bulk makes it difficult to apply to the operating room. Additionally, CT requires multiple x-ray exposures to acquire images. Typically, this level of exposure is undesirable in an operating room setting and simple x-ray is used instead. A special concern for intraoperative CT is that the patient table must be transparent to x-ray, otherwise the table will prevent imaging.
A significant advantage of CT over MRI is that there is no concern over implanted devices or metal shrapnel as in MRI. Thus a patient with unknown history, such as a trauma case, can be imaged without the potential problems of MRI.
