Diagnostic support for skins and inspection method of skin
A diagnostic support for a skin includes a radio-transparent structure that defines a folding surface of the skin and on which the skin may be stretched and consequently folded, thereby defining folded, mutually superimposed portions spaced apart from each other. The support may be used for radiographic inspection of a folded animal skin.
1. A method for inspecting a skin designed to detect defects in said skin, comprising:
obtaining a radiological image of said skin, wherein said radiological image comprises a plurality of pixels;
storing said radiological image in a memory;
obtaining a superficial image of said skin, wherein said superficial image comprises a plurality of pixels and said skin comprises at least one bonded marker that is optical and radio-opaque;
storing said superficial image in the memory; and
spatially cross-referencing said radiological image and said superficial image, wherein said spatial cross-referencing comprises:
retrieving said radiological image from the memory;
detecting at least a first discontinuity in said radiological image;
retrieving said superficial image from the memory;
detecting at least a second discontinuity in said superficial image; and
spatially cross-referencing said radiological image and said superficial image by matching at least one of said at least first discontinuity to at least one of said at least second discontinuity.
2. The method according to claim 1 , further comprising:
defining a cross-reference system common to said radiological image and to said superficial image with respect to which said first discontinuities and said second discontinuities can be referred; and
detecting a location of said defects in said skin on the basis of said first and second discontinuities.
3. The method according to claim 2 , further comprising determining first coordinates of said first discontinuities in said radiological image and second coordinates of said second discontinuities in said superficial image,
wherein said determined first coordinates define a position of said defects in said radiological image, and said determined second coordinates define a position of said defects in said superficial image.
4. The method according to claim 3 , further comprising defining a defects database that associates each of said defects in said skin with said first and second coordinates.
5. The method according to claim 4 , wherein said defects database associates a form of said defect to each of said defects and the method further comprises removing said defects from said skin based on said defects database.
6. The method according to claim 1 , wherein said radiological image is obtained using tomography.
7. A method for inspecting a skin designed to detect defects in said skin, comprising:
obtaining a radiological image of said skin, wherein said radiological image comprises a plurality of pixels;
storing said radiological image in a memory;
obtaining a superficial image of said skin, wherein said superficial image comprises a plurality of pixels;
storing said superficial image in the memory; and
spatially cross-referencing said radiological image and said superficial image, wherein said spatially cross-referencing comprises:
retrieving said radiological image from the memory;
detecting at least two first discontinuities in said radiological image;
retrieving said superficial image from the memory;
detecting at least two second discontinuities in said superficial image; and
spatially cross-referencing said radiological image and said superficial image by causing the positions of the at least two first discontinuities to coincide with the positions of the at least two second discontinuities.
8. The method according to claim 7 , further comprising:
defining a cross-reference system common to said radiological image and to said superficial image with respect to which said first discontinuities and said second discontinuities can be referred; and
detecting a location of said defects in said skin on the basis of said first and second discontinuities.
9. The method according to claim 8 , further comprising determining first coordinates of said first discontinuities in said radiological image and second coordinates of said second discontinuities in said superficial image,
wherein said determined first coordinates define a position of said defects in said radiological image, and said determined second coordinates define a position of said defects in said superficial image.
10. The method according to claim 9 , further comprising defining a defects database that associates each of said defects in said skin with said first and second coordinates.
11. The method according to claim 10 , wherein said defects database associates a form of said defect to each of said defects and the method further comprises removing said defects from said skin based on said defects database.
12. The method according to claim 7 , wherein said radiological image is obtained using tomography.
