Claims (7)

  1. A C-shaped arm (102) for use with a medical imaging system comprising: a C-shaped portion (108); a radiation source carried by the C-shaped portion (108); and a radiation detector carried by the C-shaped portion (108), wherein at least a portion of the C-shaped portion (108) is formed of a unidirectional ultra-high modulus carbon fiber material, wherein the unidirectional ultra-high modulus carbon fiber material is located within a cavity of the C-shaped portion (108), wherein the C-shaped portion (108) comprises: a first reinforcement within the cavity and adjacent to a first inner joint (744) of the C-shaped portion (108); a second reinforcement within the cavity and adjacent to a second inner joint (746) of the C-shaped portion (108), wherein the first reinforcement and the second reinforcement are formed of a unidirectional ultra-high modulus carbon fiber material.
  2. The C-shaped arm (102) of claim 1, wherein a remainder of the C-shaped portion (108) is formed of a different carbon fiber material.
  3. The C-shaped arm (102) of claim 1, wherein the C-shaped portion (108) 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 (108) of claim 3, wherein the first region and the second region extend about an inner radius of the C-shaped portion (108).
  5. The C-shaped arm (102) of claim 3, wherein the first region includes a first joint of the C-shaped portion (108) and the second region includes a different second joint of the C-shaped portion (108).
  6. The C-shaped arm (102) of claim 3, wherein the C-shaped portion (108) 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 (102) 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.

Description

TECHNICAL FIELD This disclosure relates to an imaging system with a C-arm and more particularly to a medical imaging system with a carbon fiber C-arm. BACKGROUND Radiographic medical imaging systems may provide non-invasive means for imaging internal structures (i.e., bone, tissue, etc.) of a patient. A radiographic imaging device may include a C-arm coupled to a base that supports the C-arm, a radiation source, and a radiation detector. The C-arm supports the radiation source and the radiation detector opposite the radiation source. The C-arm rotates about an examination region that includes a portion of the patient and the radiation source emits radiation that traverses the examination region. The radiation detector detects the radiation that traverses the examination region and generates a signal indicative thereof. A reconstructor processes the signal and reconstructs image data indicative of the examination region and the portion of the patient within the examination region. In US 2021/145383 various methods and systems are provided for a medical imaging system C-arm. In one example, an imaging system comprises a C-arm including an inner circumferential wall forming a first pair of grooved flanges and the outer circumferential wall forming a second pair of grooved flanges, where each of the first pair of grooved flanges and second pair of grooved flanges comprises a composite material. A C-shaped portion of the C-arm may be configured to rotate isocentrically around a rotational axis. SUMMARY The invention is set out in the claims. To the extent that any embodiment set out herein does not fall withing the scope of the claims, that embodiment does not form part of the invention. In one embodiment, the present disclosure provides 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. In another embodiment, the present disclosure provides 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. In yet another embodiment, the present disclosure provides 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.
