Abstract

A new and improved digital sensor assembly for use in a filmless radiography system is disclosed. The sensor is configured to be universal in that it can be rotated about a cable connection thereby allowing the sensor to be used both vertically and horizontally in the oral cavity. The rotatability of the sensor allows it to fit comfortably and close to a target area in an intraoral cavity. By providing a comfortable relative fit to the target area, the sensor is ergonomically improved, in terms of its comfort and feel to a dental patient. Alternative sensor assembly embodiments disclosed herein relate to quick disconnect-type coupling arrangements between the sensor body and the sensor cable.

Claims

1. A digital radiography sensor assembly, comprising a sensor body including components for generating radiography image data, and a sensor cable leading from the sensor body to either a computer which reads the data generated by the components or an image display unit, whereby said sensor body is coupled to the sensor cable via selectively disengageable male and female connectors,

wherein said sensor body is selectively rotatable relative to the sensor cable, and

wherein said male connector is disposed on the sensor body and includes a post and said female connector includes a socket occurring along a terminal end of the cable for receiving the post.

2. The digital radiography sensor assembly of claim 1, wherein said terminal end of said cable includes a radially extending flange and said sensor body includes a well for receiving said flange.

3. The digital radiography sensor assembly of claim 2, wherein said well includes a plurality of overhanging tabs for locking said flange thereunder within said well.

4. The digital radiography sensor assembly of claim 3, wherein said flange includes a plurality of cut-outs which pass over said overhanging tabs whereby upon rotation of said sensor body relative to the cable the flange is secured under the tabs.

5. The digital radiography sensor assembly of claim 4, wherein said flange includes a recess occurring between the cut-outs, said recess shaped to mate with said tabs upon sufficient rotation of the sensor body relative to said cable.

6. The digital radiography sensor assembly of claim 1, wherein said sensor body and said sensor cable are magnetically coupled.

7. The digital radiography sensor assembly of claim 1, wherein the sensor body includes a plurality of spaced apart detents which are engaged by protrusions occurring along a radially extending flange occurring on a terminal end of said cable, said detents and protrusions being of sufficient number to allow for incremental rotation of the sensor body relative to the cable.

8. A digital radiography sensor assembly, comprising a sensor body including components for generating radiography image data, and a sensor cable leading from the sensor body to either a computer which reads the data generated by the components or an image display unit, whereby said sensor body is coupled to the sensor cable via selectively disengageable male and female connectors,

wherein said sensor body is selectively rotatable relative to the sensor cable, and

wherein said male connector is disposed on a terminal end of the cable and includes a post and said female connector includes a socket in the sensor body for receiving the post.

9. The digital radiography sensor assembly of claim 8, wherein said male connector includes a ball receivable in the socket and able to swivel when fully engaged therein.

10. The digital radiography sensor assembly of claim 8, wherein said sensor body and said sensor cable are magnetically coupled.

11. A digital radiography sensor assembly, comprising a sensor body including components for generating radiography image data, and a sensor cable leading from the sensor body to either a computer which reads the data generated by the components or an image display unit, whereby said sensor body is coupled to the sensor cable via selectively disengageable male and female connectors,

wherein said sensor body and said sensor cable are magnetically coupled.

12. The digital radiography sensor assembly of claim 11, wherein said male connector is disposed on the sensor body and includes a post and said female connector includes a socket occurring along a terminal end of the sensor cable for receiving the post.

13. The digital radiography sensor assembly of claim 11, wherein a terminal end of said sensor cable includes a radially extending flange and said sensor body includes a well for receiving said flange.

14. The digital radiography sensor assembly of claim 13, wherein said well includes a plurality of overhanging tabs for locking said flange thereunder within said well.

15. The digital radiography sensor assembly of claim 14, wherein said flange includes a plurality of cut-outs which pass over said overhanging tabs whereby upon rotation of said sensor body relative to the cable the flange is secured under the tabs.

16. The digital radiography sensor assembly of claim 15, wherein said flange includes a recess occurring between the cut-outs, said recess shaped to mate with said tabs upon sufficient rotation of the sensor body relative to said cable.

17. The digital radiography sensor assembly of claim 11, wherein the sensor body includes a plurality of spaced apart detents which are engaged by protrusions occurring along a radially extending flange occurring on the terminal end of said cable, said detents and protrusions being of sufficient number to allow for incremental rotation of the sensor body relative to the cable.

18. The digital radiography sensor assembly of claim 11, wherein said sensor body is selectively rotatable relative to the sensor cable.

19. The digital radiography sensor assembly of claim 11, wherein said male and female connectors are in the form of a swiveling ball and a socket.
