Hoboken University Medical Center has been through a trying two weeks since Hurricane Sandy, but it is on its way back to normal. When the hospital evacuated before Sandy hit, about 60 patients were released to their homes and about 77 were transferred to other hospitals. Paul A. Walker, the hospital's CEO, said he's run hospitals through five other hurricanes, but Sandy was "my first flood of this magnitude." Last night, the delivery of a new CT scanner allowed the hospital to open its emergency room fully.
