1. An imaging system for acquiring multi-dimensional tomographic image data of an object, the imaging system comprising:
- a plurality of detectors to acquire image data, said detectors coupled to a supporting structure, wherein at least one of said detectors is adapted to move relative to the object during image data acquisition and wherein said detectors are adapted to rotate independently of each other, provided that image data from said detectors are collected concomitantly during a study time; and
a data analyzer adapted to acquire and/or reconstruct the image data.

22. A method for acquiring multi-dimensional tomographic image data of an object, the method comprising the steps of:
-
positioning a first detector at a first detector position with respect to the object; positioning a second detector at a second detector position with respect to the object, the second detector position being located at a different location than the first detector position; rotating the first detector while maintaining the first detector in the first detector position; maintaining the second detector stationary in the second detector position while the first detector rotates in the first detector position; and simultaneously acquiring the multi-dimensional tomographic image data from the first and second detectors while the first detector is rotated and the second detector is stationary, wherein the first detector is independently rotated to acquire a volume of interest (VOI) within the multi-dimensional tomographic image data. - View Dependent Claims (23)
