Implantable apparatus for facilitating imaging-based diagnoses

1. An implantable device comprising:

a bi-material helical coil wire having an indicator wire attached to both ends of the bi-material helical coil wire, wherein both ends of the bi-material helical coil wire remain aligned relative to one another when the implantable device is subjected to a first physical parameter such that the indicator wire remains substantially straight, and wherein both ends of the bi-material helical coil wire rotate relative to one another when the implantable device is subjected to a second physical parameter such that the indicator wire wraps around the bi-material helical coil wire.

2. The device of claim 1 , wherein each end of the bi-material helical coil is attached to an opposite end of the indicator wire.

3. The device of claim 1 , wherein the indicator wire is a segment of the bi-material helical coil.

4. The device of claim 1 , wherein the bi-material helical coil comprises multiple bi-material helical coils in a contiguous nested configuration, and wherein the indicator wire spans a length of the multiple bi-material helical coils when subjected to the first physical parameter.

5. The device of claim 4 , wherein each of the multiple bi-material helical coils in the contiguous nested configuration rotate in the same direction when subjected to the second physical parameter.

6. The device of claim 1 , wherein the indicator wire remaining substantially straight is indicative of a first physiological state, wherein the indicator wire wrapping around the bi-material helical coil wire is indicative of a second physiological state, wherein the first physiological state is a healthy state, and wherein the second physiological state is a diseased state.

7. The device of claim 1 , wherein the first physical parameter is a first temperature, and wherein the second physical parameter is a second temperature.

8. A method for determining a physiological state of an animal or human subject, comprising:

analyzing, by a computing device, images of an area of the animal or human subject, wherein an implantable device is implanted in the area, wherein the implantable device comprises a bi-material helical coil wire having an indicator wire attached to both ends of the bi-material helical coil wire, wherein the implantable device is configured to have a first form indicative of a first physical parameter that is indicative of a first physiological state, and is configured to have a second form indicative of a second physical parameter that is indicative of a second physiological state, and wherein the first form is different from the second form;

determining, by the computing device, whether the implantable device exhibits the first form or the second form by comparing a first image of the area of the animal or human subject to a second image of the animal or human subject, wherein the first form is based on a response to the first physical parameter, and wherein the second form is based on a response to the second physical parameter; and

determining, by the computing device, whether the area of the animal or human subject is healthy or diseased based on whether the implantable device exhibits the first form or the second form, wherein the first form is a healthy state and the second form is a diseased state.

9. The method of claim 8 , further comprising comparing an image of the area to a baseline image showing a baseline form of the implantable device.

10. The method of claim 8 , wherein the first form is a first size and the second form is a second size.

11. The method of claim 8 , wherein the first form is within a first range of forms, wherein the first range of forms is below a threshold value for the healthy state, and

wherein the second form is within a second range of forms, wherein the second range of forms is above a threshold for the diseased state.
