Abstract: A method of compensating for differences in detective gain between a plurality of different scanning heads in a multiple scanning head imaging plate scanner, comprising: (a) scanning each of the scanning heads across an imaging plate thereby determining the detected signal at successive locations across the imaging plate for each of the scanning heads; (b) calculating an inverse relationship to the detected signal at successive locations across the imaging plate for each of the scanning heads; (c) scanning each of the scanning heads across an imaging plate containing an image thereon, thereby determining an image value at the successive locations across the imaging plate for each of the scanning heads; and (d) applying the inverse relationship to the determined image values at the successive locations across the imaging plate for each of the scanning heads.

Abstract: A system for scanning an imaging plate, comprising: a continuous belt drive; a first scanning head mounted to the belt drive; a second scanning head mounted to the belt drive; and a laser positioned to direct a laser beam in a beam path across the imaging plate, wherein the continuous belt drive is positioned to sequentially move each of the first and second scanning heads in a path collinear with the laser beam path when moving across the imaging plate.

Abstract: A multiple-head scanning device (20) for reading an image stored on a photostimulable phosphor storage screen (10), comprising, a rotatable frame having a center (13) and an outer perimeter (15); a photomultiplier tube (40) mounted to the rotatable frame at a location proximal the center (13) of the rotatable frame; a plurality of radially extending optical trains (12) mounted to the rotatable frame at 120 degrees to one another, each optical train (12) configured to direct incident laser light towards phosphor storage screen (10) and to direct response radiation emitted by phosphor storage (10) screen in response to the incident laser light towards the photomultiplier tube (40).
