1. A system for calculating positional information of multiple movable image modality components for an acquisition event that occurs during a tomographic image capture sequence, comprising:
a positioner module, comprising
an input interface configured to receive time-stamped positional information from said multiple moveable image modality components at multiple time intervals during said tomographic image capture sequence, and said input interface configured to receive a time-stamp value query of said acquisition event,
a memory to store said time-stamped positional information for said multiple moveable image modality components at said multiple time intervals,
processor that calculates positional information by interpolation of said stored time-stamped positional information of said movable image modality components for a time-stamp value query of said acquisition event, wherein the interpolated results are calculated relative to a synchronization signal, and
an output interface to provide positional information on all of said moveable image modality components in response to said time-stamp value query calculated by said processing unit, and
a clock associated with each of said multiple movable modality components to provide a time-stamp for each positional event of said movable modality components at multiple time intervals during said tomographic image capture sequence, wherein each of said clocks is interconnected in order to accept said synchronization signal to synchronize the times of said clocks.
