Non-circular C-arm for fluoroscopic imaging equipment |
摘要 |
A system and method of x-ray imaging is provided that includes a support base, a bearing assembly supported by the support base, and a non-circular positioning arm rotating in a semi-elliptical path relative to the support base through the bearing assembly. The non-circular positioning arm has first and second distal ends. The shape of the non-circular positioning arm conforms to a shape of a portion of a linear spiral. The system and method also includes an x-ray source located at the first distal end of the positioning arm, an x-ray detector located at the second distal end of the positioning arm. The x-ray source emits a conical beam having a theoretical central beam. The central beam passes through an origin of the linear spiral. The system also includes an imaging isocentric area located between the x-ray source and the x-ray detector. The imaging isocentric area remains substantially constant when the noncircular positioning arm rotates relative to the support base.
