    摘要: C-arm systems and method for making and using continuous C-arm spin acquisition trajectories for dynamic imaging and improved image quality are described. In such systems and methods, a C-arm gantry, coupled to a C-arm support assembly, is adapted to retain an x-ray source and an x-ray detector. The C-arm gantry is selectively rotatable relative to the C-arm support assembly about both a C-arm axis and a pivot-axis to displace the x-ray source and the x-ray detector along a continuous C-arm spin trajectory. The C-arm system is adapted for continuous three-dimensional acquisition of data along the continuous C-arm spin trajectory including a plurality of shorts arcs and a plurality of long arcs. The C-arm system is adapted for continuous three-dimensional acquisition of data along the continuous C-arm spin trajectory to provide continuous three-dimensional imaging of dynamic processes.

    摘要: A method includes, in a bi-plane interventional imaging system, moving a first C-arm supporting a first X-ray source and a first X-ray detector about first and second axes while obtaining a plurality of first X-ray attenuation data sets relating to a subject of interest; moving a second C-arm, positioned crosswise with respect to the first C-arm and supporting a second X-ray source and a second X-ray detector, about the first axis while obtaining a plurality of second X-ray attenuation data sets relating to the subject of interest; and synchronizing the movement of the first and second C-arms to avoid collision therebetween.

    摘要: A control system for operating a beam pumping unit includes a strain gauge and a beam pumping unit controller. The strain gauge is coupled to a Samson post of the beam pumping unit, and is configured to measure a Samson post strain. The beam pumping unit controller is coupled to the strain gauge and is configured to operate the beam pumping unit to induce a variable load on a rod of the beam pumping unit. The beam pumping unit controller is further configured to receive the Samson post strain from the strain gauge and compute the variable load based on the Samson post strain.
