Radiation sensitive recording plate with orientation identifying marker, method of making, and of using same
First Claim
1. A radiation-recording plate constructed and arranged to have a capacity to form an image of an object upon exposure to radiation impinging on the object and then incident upon the plate from a front side and to have a capacity to form an image of the object upon exposure to radiation impinging on the object and then incident upon the plate from a back side,the plate including prior to exposure a marker that produces a mark detectable in the image after exposure to radiation incident upon the plate from only one of the front side and the back side without constraint as to which, and indicative of both from which of the front side and the back side the plate is exposed to the radiation and indicative of any mirroring transformations performed upon an image recovered from the plate after exposure to the radiation.

Abstract
A radiation-recording plate (104) can be constructed and arranged to form an image upon exposure from both a front side and a back side. The plate can include a marker (201) detectable in the image (205) after exposure and indicative of which of the front side and the back side the plate is exposed from. The marker may comprise a medium opaque to the radiation coating a region that does not interfere with reading the image when the plate is exposed from either side, or may be a void in the sensitive layer of the plate. The marker may have horizontal asymmetry about a vertical axis relative to a normal image orientation, or the marker may have vertical asymmetry about a horizontal axis relative to a normal image orientation. The marker may further comprise a front side marker and a back side marker whose appearance in an image on the plate indicates exposure from the front side or the back side respectively. A method of identifying a side from which a radiation-recording plate has been exposed to radiation may comprise: incorporating in the plate (104), in a position that substantially does not interfere with an image area of the plate, a marker (201) whose appearance in the image identifies which side the plate is exposed from; exposing the plate to the radiation; and observing the image (205) for the identification of the side of the plate exposed. A method of making a radiation sensitive plate having at least one radiation sensitive layer may comprise: providing a film sensitive to the radiation on a first side of the radiation sensitive plate; and applying a suspension of a heavy metal in a binder to a region of a second side of the radiation sensitive layer.

1. A radiation-recording plate constructed and arranged to have a capacity to form an image of an object upon exposure to radiation impinging on the object and then incident upon the plate from a front side and to have a capacity to form an image of the object upon exposure to radiation impinging on the object and then incident upon the plate from a back side,
the plate including prior to exposure a marker that produces a mark detectable in the image after exposure to radiation incident upon the plate from only one of the front side and the back side without constraint as to which, and indicative of both from which of the front side and the back side the plate is exposed to the radiation and indicative of any mirroring transformations performed upon an image recovered from the plate after exposure to the radiation.

39. A method of identifying a side from which a radiation-recording plate having a capacity to form an image of an object upon exposure to radiation impinging on the object and then incident upon the plate from a front side and having a capacity to form an image of an object upon exposure to radiation impinging on the object and then incident upon the plate from a back side has been exposed to radiation, comprising:
-
exposing the plate to the radiation incident upon the plate from only one of the front side and the back side without constraint as to which; obtaining an image of the object produced by exposing the plate to the radiation impinging on the object and then incident upon the plate; and incorporating in the plate prior to exposure, in a position that substantially does not interfere with an image area of the plate, a marker producing a mark whose appearance in an image identifies both which side the plate is exposed from and which is indicative of any mirroring transformations performed upon an image recovered from the plate after exposure; and observing the image for the identification of the side of the plate exposed and for the indication of any mirroring transformations. - View Dependent Claims (40, 41, 42, 43, 44, 45)

46. A method of making a radiation sensitive plate having at least one radiation sensitive layer, comprising:
-
providing a film sensitive to the radiation on a first side of the radiation sensitive plate; applying a suspension of a heavy metal in a binder to a region of a second side of the radiation sensitive layer; providing a detectable marker on the first side; and
whereinthe detectable marker and the suspension of a heavy metal applied combined are distinct and asymmetric.

47. An image storage device holding an image data structure comprising:
-
a recording medium; a data structure defined by a record in the recording medium of an image produced by exposure to radiation of a radiation-sensitive medium; and a mark embedded in the data structure, the mark produced during the exposure of the radiation-sensitive medium, and the mark both indicative of which side the radiation-sensitive medium was exposed from and indicative of any mirroring transformations performed upon the image in whose record the mark is embedded. - View Dependent Claims (48, 49, 50, 51, 52)
