Use caution until it’s fixed

The firm received a complaint where, during patient positioning, the technologist was adjusting the patient table height and the table failed to stop when the control was released and contacted the CT gantry. The problem could not be duplicated at the site, so to avoid further issues while a root cause investigation was pursued, Hitachi choose to add an optional touch sensor to the gantry to add a redundant level of protection. It is conceivable that a patient s extremity may be caught between the tabletop and the gantry surface during uncontrolled motion or that the table contact of the gantry might cause internal damage to the unit.
