Abstract
Disclosed is a dental X-ray imaging device having a curved detector. The dental X-ray imaging device according to the present invention comprises: an X-ray source for radially emitting X-rays; and a curved detector formed in a cylindrical two-dimensional curved shape or a round three-dimensional curved shape, which is arranged to be spaced apart at a predetermined distance from the X-ray source and has substantially the same radius of curvature as the predetermined distance.
Claims10
A dental X-ray imaging device comprising:
- an X-ray source configured to emit X-rays;
- an X-ray detector having a flexible incidence surface;
- and
- a support frame configured to adjust a curvature of the X-ray detector,
- wherein the support frame is configured to vary the coverture of the X-ray detector depending on the distance from the X-ray source to an incident surface.
A dental X-ray imaging device for panoramic radiography comprising:
- an X-ray source configured to emit X-rays to produce a panoramic image;
- an X-ray detector having a flexible incidence surface, wherein the detector includes a plurality of pixels, wherein a curvature of each of the pixels, given that an incidence surface of each pixel has a tilted angle θ relative to an incidence surface of a neighboring pixel, satisfies a following expression of relation within an error range of 20%:
- one pixel curvature=180°−2θ,
- wherein, θ=a cos (a size of one pixel/2)/FDD (wherein, FDD=the predetermined distance);
- and
- a support frame configured to adjust a curvature of the X-ray detector,
- wherein the support frame is configured to adjust the curvature of the X-ray detector to have at least one of (1) a three-dimensional curved shaped with curvatures in a vertical direction and a horizontal direction and (2) a two-dimensional curved shape having a curvature only in a vertical direction.
