Patent ID: 8768029

Claim:
A method of acquiring image data of a subject with an imaging system, comprising: acquiring initial image data with a gantry that completely annularly encompasses a human subject of at least a portion of the human subject with a mobile imaging system including the gantry movably attached to a mobile cart; constructing an initial three-dimensional model of the portion of the human subject prior to a procedure performed on the portion of the human subject; acquiring discriminatory discrete location image data of the human subject at a location of the procedure after performing the procedure on the human subject at the location; executing instructions with a processor system to compare the acquired discriminatory discrete location image data to the constructed initial three-dimensional model of the portion of the human subject; and executing instructions with the processor system to identify specific regions of threshold change between the acquired discriminatory discrete location image data and the constructed initial three-dimensional model of the portion of the human subject; wherein constructing the initial three dimensional model of the portion of the human subject includes executing instructions with a processor system to determine errors between simulated projection image data of a theoretical model and the initial image data acquired of at least a portion of the human subject with the imaging system; wherein the specific regions of threshold change include regions of the patient that have changed beyond a threshold selected for comparison between the discrete location image data and forward projection of the initial three dimension volumetric model of the human subject due to a procedure performed on the patient, movement of the patient, or combinations thereof; wherein executing instructions with the processor system to determine a comparative path includes determining an initial comparative location of a detector, determining a final location of the detector, and determining movements of the detector and the gantry to allow detecting of a comparative image data to allow a construction of a comparative three-dimensional model to illustrate a current configuration of the human subject; wherein the comparative three dimensional model is constructed by executing instructions with the processor system to update the initial three dimensional model based upon the comparative image data acquired when moving the imaging system along the comparative path.
