Radiographic marker for inclination angle of imaging receiver
View Patent ↗A radiography marker for indicating the inclination angle of a radiography imaging receiver has a portion defining at least one area transparent to x-radiation and an angle indicator element attached to the portion defining at least one area at a pivot point and manually adjustable along the portion defining at least one area to set any of a plurality of angular positions over at least a portion of the at least one area transparent to x-radiation. At least a portion of the indicator element is opaque to x-radiation.

2. A radiography marker for indicating an inclination angle of a radiography receiver, the marker comprising:
a portion defining at least one area transparent to x-radiation;
an angle indicator element attached to the portion defining at least one area at a pivot point, the angle indicator element being manually settable to a plurality of angular positions over at least a portion of the at least one area, wherein at least a portion of the indicator element is opaque to x-radiation; and
a coupling for detachably mounting the portion defining at least one area against a surface of a radiography receiver;
wherein the portion defining at least one area is a plate and the coupling comprises an offset plate.
3. A radiography marker for indicating an inclination angle of a radiography receiver, the marker comprising:
a portion defining at least one area transparent to x-radiation; and
an angle indicator element attached to the portion defining at least one area at a pivot point, the angle indicator element being manually settable to a plurality of angular positions over at least a portion of the at least one area, wherein at least a portion of the indicator element is opaque to x-radiation;
wherein the portion defining at least one area further comprises at least one detent at an angular position.
4. A radiography marker for indicating an inclination angle of a radiography receiver, the marker comprising:
a portion defining at least one area transparent to x-radiation; and
an angle indicator element attached to the portion defining at least one area at a pivot point, the angle indicator element being manually settable to a plurality of angular positions over at least a portion of the at least one area, wherein at least a portion of the indicator element is opaque to x-radiation;
wherein the portion defining at least one area further comprises left and right position markers.
5. A radiography marker for indicating an inclination angle of a radiography receiver comprising:
a portion defining at least one area transparent to x-radiation;
an angle indicator element attached to the portion defining at least one area at a pivot point, the angle indicator element being manually settable to a plurality of angular positions over at least a portion of the at least one area, wherein at least a portion of the indicator element is opaque to x-radiation; and
a coupling for detachably mounting the portion defining at least one area against a surface of a radiography receiver outside a diagnostically relevant imaging area of the receiver.
6. The radiography marker of claim 5 wherein the portion defining at least one area further comprises means for defining an angular position.
7. The radiography marker of claim 5 wherein the angular positions are discrete positions.
8. The radiography marker of claim 5 wherein the angular positions are continuous.
9. The radiography marker of claim 5 wherein the angle indicator element comprises a movable arm.
10. The radiography marker of claim 5 wherein the portion defining at least one area is a plate and the coupling comprises an attached offset plate.
11. A method for storing image metadata for a radiography image comprising:
providing a radiography marker having a pivotable member, at least a portion of the pivotable member being opaque to x-radiation;
attaching the marker along an edge portion of a radiography receiver;
manually setting the pivotable member of the marker to a position to indicate an inclination angle of the receiver;
obtaining x-ray image data from the receiver while the marker is attached;
detecting the position of the pivotable member of the marker in the image data;
computing the inclination angle from the position of the pivotable member; and
storing the inclination angle with the image data from the receiver.
