Computer radiographic scanner utilizing a scan bar

摘要

The scanning device for radiographic media ( 28 ) is made of a rotatable vacuum drum ( 40 ) has an external surface ( 42 ) that, rotates about a longitudinal axis ( 7 ); the radiographic media is disposed on the external surface; a moveable scan bar ( 24 ) is mounted on two translation rods adjacent the drum; at least one scan module is mounted on the moveable scan bar; a translation drive is connected to the moveable scan bar for moving the moveable scan bar perpendicular to the longitudinal axis; an analog to digital converter ( 32 ) in communication with the scan modules receives scanned signals from the scan modules; a control process unit ( 34 ) receives scanned signals; and an output device ( 36 ) for writes the received scanned signals onto diagnostic media.
