摘要:
A system for motion control of a cone-beam tomography recording device includes a drive system configured to position a paired radiation source and radiation detector relative to an object. The system further includes a controller configured to: initiate a trigger plan operable as a function of a constant frequency control signal, activate the paired radiation source and radiation detector in accordance with the trigger plan, drive, in response to the trigger plan, the first drive system to a steady operating state derived as a function of the constant frequency, capture a plurality of broadcast radiation signals representative of a plurality of two dimensional images of the object such that the two dimensional images are defined equidistant positions defined by the trigger plan and as a function of the constant frequency signal, and generate a three dimensional representation of the object based on the plurality of two dimensional images.
