1. An apparatus for imaging a structure of interest, comprising:
- a plurality of imaging detectors mounted on a gantry, each of the plurality of imaging detectors having a field of view (FOV), each of the plurality of imaging detectors being independently movable with respect to each other, the plurality of imaging detectors being positioned to image a structure of interest within a patient;
a data acquisition system for receiving image data detected within the FOV of each of the plurality of imaging detectors; and
a plurality of pivots interconnecting the gantry and the plurality of imaging detectors, at least one of the plurality of imaging detectors movable at a pivot point in two different directions transverse to each other.

Abstract
An apparatus for imaging a structure of interest comprises a plurality of imaging detectors mounted on a gantry. Each of the plurality of imaging detectors has a field of view (FOV), is independently movable with respect to each other, and is positioned to image a structure of interest within a patient. A data acquisition system receives image data detected within the FOV of each of the plurality of imaging detectors.

16. A method for acquiring images of a structure of interest with a plurality of imaging detectors, comprising:
-
positioning a plurality of imaging detectors proximate to a structure of interest, each of the plurality of imaging detectors having a field of view (FOV), at least one of the plurality of imaging detectors being independently movable at a pivot point in two different directions transverse to each other to change the FOV; aiming at least a sub-set of the plurality of imaging detectors to image at least a portion of the structure of interest within the FOV; acquiring image data with at least the sub-set of the plurality of imaging detectors; and combining the image data received from the plurality of imaging detectors to form a composite image. - View Dependent Claims (17, 18, 19, 21, 22, 23, 24)
