Abstract

The present disclosure relates to a C-shaped arm for use with a medical imaging system. In accordance with certain embodiments, the C-shaped arm comprises a C-shaped portion, a radiation source carried by the C-shaped portion, and a radiation detector carried by the C-shaped portion, wherein at least a portion of the C-shaped portion is formed of a unidirectional ultra-high modulus carbon fiber material.

First claim

What is claimed is:

1 . A C-shaped arm for use with a medical imaging system comprising:
a C-shaped portion; a radiation source carried by the C-shaped portion; and a radiation detector carried by the C-shaped portion,
wherein at least a portion of the C-shaped portion is formed of a unidirectional ultra-high modulus carbon fiber material.

2 . The C-shaped arm of claim 1 , wherein a remainder of the C-shaped portion is formed of a different carbon fiber material.

3 . The C-shaped arm of claim 1 , wherein the C-shaped portion comprises:
a first region formed of unidirectional ultra-high modulus carbon fiber material; and a different second region formed unidirectional ultra-high modulus carbon fiber material.

4 . The C-shaped portion of claim 3 , wherein the first region and the second region extend about an inner radius of the C-shaped portion.

5 . The C-shaped arm of claim 3 , wherein the first region includes a first joint of the C-shaped portion and the second region includes a different second joint of the C-shaped portion.

6 . The C-shaped arm of claim 3 , wherein the C-shaped portion further comprises:
a third region extending between the first region and the second region, wherein the third region is formed of a different carbon fiber material.

7 . The C-shaped arm of claim 1 , wherein the unidirectional ultra-high modulus carbon fiber material is located within a cavity of the C-shaped portion.

8 . The C-shaped portion of claim 7 , wherein the C-shaped portion comprises:
a first reinforcement within the cavity and adjacent to a first inner joint of the C-shaped portion; a second reinforcement within the cavity and adjacent to a second inner joint of the C-shaped portion,
wherein the first reinforcement and the second reinforcement are formed of a unidirectional ultra-high modulus carbon fiber material.

9 . The C-shaped arm of claim 1 , wherein the radiation source is within a cavity of the C-shaped potion and further comprising:
a removable cover formed of a carbon fiber material, wherein the removable cover defines a radiation outlet for radiation emitted by the radiation source.

10 . A medical imaging system comprising:
a C-arm; a radiation source and a radiation detector carried by the C-arm; a base; an extended portion coupled to the C-arm and the base,
wherein the C-arm is configured at least 220° about an examination region.

11 . The medical imaging system of claim 10 , wherein at least a portion of the C-arm is formed of a carbon fiber material.

12 . The medical imaging system of claim 11 , wherein the carbon fiber material is a unidirectional ultra-high modulus carbon fiber material.

13 . The medical imaging system of claim 11 , wherein C-arm comprises:
a first region formed of unidirectional ultra-high modulus carbon fiber material; and a different second region formed unidirectional ultra-high modulus carbon fiber material.

14 . The medical imaging system of claim 13 , wherein the first region and the second region extend about an inner radius of the C-shaped arm.

15 . The medical imaging system of claim 10 , wherein the portion of the C-arm that is formed of a carbon fiber material is located within a cavity of the C-shaped arm.

16 . The medical imaging system of claim 10 , wherein the C-arm is formed of a of a unidirectional ultra-high modulus carbon fiber material and a different carbon fiber material.

17 . The medical imaging system of claim 16 , wherein the C-arm further comprises:
a first reinforcement within a cavity of the C-arm and adjacent to a first inner joint of the C-arm; and a second reinforcement within the cavity and adjacent to a second inner joint of the C-arm, wherein the first reinforcement and the second reinforcement are formed of the unidirectional ultra-high modulus carbon fiber material.

18 . The medical imaging system of claim 10 , wherein the radiation source is within a cavity of the C-arm and the C-arm further comprises:
a removable cover formed of a carbon fiber material, wherein the removable cover defines a radiation outlet for radiation emitted by the radiation source.

19 . A method comprising:
acquiring first projection data with a medical imaging system that includes a C-arm that carries a radiation source and a detector, wherein the C-arm is at a first position when the medical imaging system acquires the first projection data,
wherein a portion of the C-arm is formed of a unidirectional ultra-high modulus carbon fiber material;
rotating the C-arm to a second position; acquiring second projection data with the medical imaging system when the C-arm is at the second position; reconstructing an image form at least one of the first projection data and the second projection data; and displaying the reconstructed image.

20 . The method of claim 19 , wherein the portion of the C-arm formed of the unidirectional ultra-high modulus carbon fiber material is located within a cavity of the C-arm.
