Interventional computerized tomography system with reduced physician exposure

摘要

A CT system for use in interventional procedures on a patient (20) supported by a support surface (24). The system includes a normal mode in which a patient is irradiated over an angle including irradiation from a general direction above the support surface, and a reduced angle irradiation mode in which the patient is irradiated only from an angle at which a physician is indicated as not being present or is assumed not to be present.
