1. An imaging system for acquiring image data of a subject, comprising:
a mobile cart configured to move from a first location to a second location;
a gantry movably attached to the mobile cart and configured to be positioned relative to a region of interest;
a detector moveable with and relative to the gantry to acquire comparative image data; and
a processor configured to execute instructions to:
acquire initial image data of the region of interest by moving at least one of the gantry or the detector from a first position to a final position relative to the region of interest while acquiring a selected image data set of the region of interest via the detector;
construct an initial three-dimensional model of at least a portion of the region of interest based on the acquired selected image data set;
compare an acquired discriminatory discrete location image data to the constructed initial three-dimensional model of the portion of the region of interest;
identify specific regions having a threshold change between the acquired discriminatory discrete location image data and the constructed initial three-dimensional model of the portion of the region of interest;
determine at least one location of at least one of the detector or the gantry to acquire comparative image data regarding the specific regions having the threshold change;
acquire the comparative image data at the determined at least one location of at least one of the detector and the gantry;
construct a comparative model of the region of interest based on the constructed initial three-dimensional model and the acquired comparative image data; and
display the constructed comparative model of the region of interest to illustrate changes to the region of interest;
wherein the gantry includes an annular inner wall and an annular outer wall that encloses a volume and the detector is configured to move within the volume;
wherein the detector is configured to move to the at least one location alone within the volume or with movement of the gantry;
wherein the detector is operable to move independent of the gantry and the gantry is operable to move independent of the mobile cart;
wherein the threshold change is about 0.1% to about 10%.
