Patent ID: 7122823

Claim:
A radiation imaging apparatus comprising: a photostimulable phosphor plate: a first radiation source for propagating first radiation in a first radiation path toward the plate, such that the first radiation is incident on the plate at a first radiation incidence angle, the first radiation stimulating the plate to form an image within the plate; a second radiation source for propagating second radiation in a second radiation path toward the plate, such that the second radiation is incident on the plate at a second radiation incidence angle; the photostimulable phosphor plate for emitting image radiation in a third radiation path, the image radiation based on interaction of the second radiation with the image in the plate; a lens disposed in the second radiation path for refracting the second radiation such that the second radiation incidence angle is substantially equivalent to the first radiation incidence angle at multiple points on the plate, wherein the lens is also disposed in the third radiation path for receiving and transmitting the image radiation; and a detection device disposed in the third radiation path for receiving the image radiation from the lens and for generating an electrical image signal based on the image radiation.
