The system can be switched between AP mode and PA mode. For example, AP mode is employed in examinations involving endoscopy to ensure that the endoscopist has sufficient work space. On the other hand, PA mode is employed in GI studies and angiography in order to position the FPD as close to the patient as possible to ensure that high-quality images are obtained. In PA mode, a switch on the side of the FPD can be used to move the FPD while confirming the distance from the patient. Thus, both sufficient work space for the operator and high image quality can be achieved while maximizing safety.
