Phantom for rendering biological tissue regions
Models of anatomical parts and methods utilizing and fabricating such anatomical models are provided. The model can include an assembly of one or more optically transmissive media having a first portion and a second portion. The one or more optically transmissive media can be configured to provide similar optical properties as that between two regions of the anatomical part. For example, in an example eye model, the two regions can be a corneal surface and/or retina regions of an eye. A rendered retina can be formed in the second portion of the assembly and can be representative of the retina of the eye. The rendered retina can have one or more features associated with the retina of the eye.
1. An eye model, comprising:
a substantially solid state assembly of one or more optically transmissive media having a first portion and a second portion, the one or more optically transmissive media providing similar optical properties as that between a corneal surface and a retina of an eye;
a rendered retina disposed in the second portion of the assembly and representative of the retina of an eye, the rendered retina having one or more volume features associated with the retina of the eye,
wherein the one or more features comprises one or more layers associated with the rendered retina.
2. The eye model of claim 1 , wherein the substantially solid state assembly comprises substantially entirely glass or polymer.
3. The eye model of claim 1 , wherein the one or more optically transmissive media substantially comprises a single piece of optically transmissive material, the first portion defining the rendered corneal surface, the second portion defining the rendered retina.
4. The eye model of claim 3 , wherein the single piece of transmissive material further defines a pupil stop formed by a reduction in lateral dimension along an axis extending from the rendered corneal surface to the rendered retina.
5. The eye model of claim 1 , further comprising a rendered choroidal/sclera reflector.
6. The eye model of claim 1 , wherein the one or more layers further comprise a feature defining a rendered foveal pit or rendered optical nerve head.
7. The eye model of claim 1 , wherein at least one layer comprises nanoparticles.
8. The eye model of claim 7 , wherein at least one other layer comprises a diffusion layer adjacent the nanoparticles.
9. The eye model of claim 1 , wherein a difference in index of refraction between at least two adjacent layers is less than about 0.1.
10. The eye model of claim 1 , wherein at least one surface of the one or more layers has surface roughness.
11. The eye model of claim 10 , wherein at least one interface between at least two layers has surface roughness.
12. The eye model of claim 1 , wherein at least two layers have respective optic axes with different orientations.
13. The eye model of claim 1 , further comprising a rendered choroidal/sclera reflector.
14. An eye model, comprising:
a substantially solid state assembly of one or more optically transmissive media having a first portion and a second portion, the one or more optically transmissive media providing similar optical properties as that between a corneal surface and a retina of an eye;
a rendered retina disposed in the second portion of the assembly and representative of the retina of an eye, the rendered retina having one or more volume features associated with the retina of the eye,
wherein the substantially solid state assembly comprises substantially entirely glass or polymer.
15. The eye model of claim 14 , wherein the one or more optically transmissive media substantially comprises a single piece of optically transmissive material, the first portion defining the rendered corneal surface, the second portion defining the rendered retina.
16. The eye model of claim 14 , wherein the single piece of transmissive material further defines a pupil stop formed by a reduction in lateral dimension along an axis extending from the rendered corneal surface to the rendered retina.
17. The eye model of Claim 14 , further comprising a rendered choroidal/sclera reflector.
