Improvements in imaging devices and methods for multiple image acquisition

An imaging device for acquiring in vivo images of a region of a subject's body, the imaging device comprising:

• at least two energy sources;
• at least two energy detectors for detecting energy from the at least two energy sources passing through the region of the subject's body located between the energy sources and the energy detectors, wherein a first source-detector pair is located in a first plane, and a second source-detector pair is located in a second plane, wherein the first plane and the second plane intersect through the region of the subject's body to be imaged;
• a motion assembly configured to achieve relative movement between at least one of the source-detector pairs and the subject;
• and
• a controller configured to:
• operate the energy sources and detectors while stationary, to acquire a time series of in vivo images of the region of the subject's body;
• and
• operate the motion assembly and at least one source-detector pair to achieve relative movement between the at least one source-detector pair and the subject to obtain a second set of images at each of a plurality of image angles in the plane of the source-detector pair.
