Claims84
A method to derive quantitative information on bone structure from a dental x-ray image comprising:
- (a) obtaining a dental x-ray image, wherein the dental x-ray image includes (i) at least a portion of the maxilla or mandible and (ii) an external standard for determining bone structure;
- and
- (b) analyzing the image obtained in step (a) to derive quantitative information on bone structure.
A method to derive quantitative information on bone structure from an x-ray image comprising:
- (a) obtaining an x-ray image;
- and
- (b) analyzing the image obtained in step (a) using one or more indices selected from the group consisting of Hough transform, skeleton operator, morphological operators, mean pixel intensity, variance of pixel intensity, fourier spectral analysis, fractal dimension, morphological parameters and combinations thereof, thereby deriving quantitative information on bone structure.
An x-ray assembly for determining bone mineral density or bone structure comprising
- (a) a hygienic cover;
- (b) x-ray film and
- (d) a calibration phantom comprising at least one marker positioned in an area of known density or structure.
A kit comprising a hygienic cover;
- a calibration phantom for bone structure or bone density comprising an integrated geometric pattern;
- an x-ray imaging assembly and computer programs, wherein said computer programs analyze and assess bone mineral density or bone structure.
An x-ray assembly for determining bone mineral density or bone structure comprising
- (a) a hygienic cover;
- (b) x-ray film and
- (d) a calibration phantom for measuring bone mineral density or structure or combinations thereof.
