Method and apparatus for associating patient and exposure related data with a radiation image
View Patent ↗Patient identification data and/or exposure related data or a code uniquely identifying at least one of these data is transferred shortly before or during exposure to a radio-frequency tag or the like coupled to a radiation detector. Transfer may be executed through the intermediary of a reader/writer coupled to a source of radiation.
1. A method of associating data with a radiographic image, which image is carried on a radiation detector, comprising transferring at least one of patient identification data and exposure related data or a code uniquely identifying at least one of said data from an identification station to an identification means coupled to said radiation detector in the period of time between exposure of a patient to obtain said radiographic image and a subsequent relative displacement of a source of radiation used to obtain said radiographic image and said radiation detector.
2. A method according to claim 1 wherein at least one of said patient identification data and exposure related data or a code uniquely identifying said data is transferred from said identification station onto a reader/writer coupled to said source of radiation and from said reader/writer onto said identification means coupled to said detector.
3. A method according to claim 2 wherein said identification means comprises a radio-frequency tag coupled to a cassette conveying said detector.
4. A method according to claim 3 wherein said detector comprises a photo-stimulable phosphor screen.
5. A method according to claim 4 wherein said detector comprises a digital radiography detector.
6. A method according to claim 1 wherein said identification means comprises a radio-frequency tag coupled to a cassette conveying said detector.
7. A method according to claim 6 wherein said detector comprises a photo-stimulable phosphor screen.
8. A method according to claim 7 wherein said detector comprises a digital radiography detector.
9. A method according to claim 1 wherein said detector comprises a photo-stimulable phosphor screen.
10. A method according to claim 1 wherein said detector comprises a digital radiography detector.
11. A radiography system comprising:
a workstation arranged for entering patient identification data and/or exposure related data,
a radiation detector capable of carrying a radiographic image of a patient,
an electronic identification means coupled with said detector, and
a source of radiation provided with a reader/writer device arranged for communicating said data or a code uniquely identifying said data with said workstation and with said electronic identification means,
wherein the data communication with said electronic identification means is performed in the period of time between exposure of a patient to obtain a radiographic image and a subsequent relative displacement of a source of radiation used to obtain said radiographic image and said radiation detector.
12. A radiography system according to claim 11 wherein said radiation detector comprises a photo-stimulable phosphor screen.
13. A radiography system according to claim 12 wherein said radiation detector comprises a digital radiography detector.
14. A radiography system according to claim 13 wherein said electronic identification means comprises a radio-frequency tag.
15. A radiography system according to claim 12 wherein said electronic identification means comprises a radio-frequency tag.
16. A radiography system according to claim 11 wherein said radiation detector comprises a digital radiography detector.
17. A radiography system according to claim 11 wherein said electronic identification means comprises a radio-frequency tag.
