Abstract

The present invention relates to a novel approach means of screening various skin surfaces, including hard to reach areas of the human body, as well as more commonly seen areas such as the foot. The present invention can help patients, especially those who are immobile or those with diabetes self-monitor and transmit the skin condition accurately, so that medical providers may assess the risk or presence of skin tissue breakdown. Thus, provision is made for a remote screening device that can be used in telemedicine or home self-monitoring approaches and offers high resolution image, without artifacts or other distortions that might arise from images taken of feet that have been compressed through standing and the like.

Claims

1. A system for screening skin for tissue damage comprising:

a support frame structure;

at least one image acquisition device;

a retention framework structure for reception of, and stable retention of, said at least one image acquisition device, said retention framework attached to said support frame structure, wherein;

said at least one image acquisition device is situated with said retention framework so as to be separate from any other structure of said system for screening skin for tissue damage, so as to acquire images without artifacts or other distortions.

2. The system for screening skin for tissue damage of claim 1 further comprising a reflective-based multiple field imaging solution affixed to said support frame structure.

4. The system for screening skin for tissue damage of claim 1 or 3, said system further comprising a change documentation module.

5. The system for screening skin for tissue damage of claim 4, wherein said image acquisition device is chosen from the group comprising:

a thermal imager, IR imager, a photographic still image camera, or a dual use thermal/photographic still image camera, either singly or in tandem;

said image acquisition devices outputting at least one of the following images chosen from the group comprising;

thermal images, IR images, or photographic still images, viewable independently or together as an overlay composite image.

6. The system for screening skin for tissue damage of claim 5, said system further comprising a 3-D rendering module.

7. The system for screening skin for tissue damage of claim 5, said system further comprising a software based image acquisition module, and includes a bimodal overlay.

8. The system for screening skin for tissue damage of claims 1 or 3, wherein said image acquisition device is chosen from the group comprising:

a thermal imager, IR imager, a photographic still image camera, or a dual use thermal/photographic still image camera, either singly or in tandem;

said image acquisition devices outputting at least one of the following images chosen from the group comprising;

thermal images, IR images, or photographic still images, viewable independently or together as an overlay composite image.

9. The system for screening skin for tissue damage of claim 8, said system further comprising a 3-D rendering module.

10. The system for screening skin for tissue damage of claim 8, said system further comprising a software based image acquisition module, and includes a bimodal overlay.

11. The system for screening skin for tissue damage of claims 1 or 3, wherein said support frame structure comprises an extendable portable stabilizer pole.

12. The system for screening skin for tissue damage of claims 1 or 3, wherein said support frame structure comprises a flexible extending structure having a flexible member.

3. A system for screening skin for tissue damage comprising:

a support frame structure;

a mobility track imaging solution structure having at least one image acquisition device, said mobility track imaging solution being affixed to said support frame structure;

a retention framework structure for reception of, and stable retention of, said at least one image acquisition device, said retention framework structure being affixed to said mobility track imaging solution structure wherein;

said at least one image acquisition device is situated with said retention framework structure so as to be separate from any other structure of said system for screening skin for tissue damage, so as to acquire images without artifacts or other distortions.
