Abstract

A high speed translation device for use with radiographic media with a scanning stage (10) adapted for movement in a first and second direction (11, 13) along a first axis (14); a second scanning module stage (12) disposed opposite the first scanning stage for movement in a third and fourth direction (15, 16) along a second axis (17); a first and a second scanning module mounted on the first and second scanning stages, respectively; a control processing unit (58) adapted to combine the scanned images from each scanning module; and a continuous drive cable (20) with a first pin (22) for sequentially moving the scanning stage from a first position (25) to a second position (27); a second pin (30) for moving the balancing stage simultaneously with the scanning stage initially in a third position (29) to the fourth position (31); wherein the first pin moves the balancing stage from the fourth position to the third position while second pin moves the scanning stage from the second position to the first position.

Dependent claims

A high speed scanning device for use with radiographic media comprising:

a) a first scanning stage comprising a first scanning stage slot, wherein the first scanning stage is adapted for movement in a first direction and a second direction along a first axis;
b) a second scanning stage comprising a second scanning stage slot, wherein the second scanning stage is disposed on an opposite side of the radiographic media from the first scanning stage and is adapted for movement in a third direction and a fourth direction along a second axis;
c) a first scanning module mounted on the first scanning stage;
d) a second scanning module mounted to the second scanning stage;
e) a control processing unit adapted to combine the scanned images from the first and second scanning modules;
and
f) a continuous drive cable engaging a drive pulley with a drive motor for rotating the drive pulley, wherein the continuous drive cable further comprises:
i) a first pin for sequentially moving the first scanning stage from a first position to a second position by engaging the first scanning stage slot;
and
ii) a second pin for moving the second scanning stage simultaneously with the first scanning stage initially from a third position to a fourth position by engaging the second scanning stage slot;
further, wherein, in sequence, the first pin moves the second scanning stage from the fourth position to the third position while the second pin moves the first scanning stage from the second position to the first position.
