Abstract
A gamma ray camera system is provided, which includes a lens system comprising at least one crystal diffraction lens, and a camera. The camera is configured to perform gamma ray imaging of a first region of a volume of interest using the lens system, and perform gamma ray imaging of a second region of the volume of interest without using the lens system. Other embodiments are also described.

A gamma ray camera system comprising:
- a lens system comprising at least one crystal diffraction lens;
- and
- a camera, configured to:
- perform three-dimensional gamma ray imaging of a first region of a volume of interest using the lens system, and
- perform three-dimensional gamma ray imaging of a second region of the volume of interest without using the lens system,
- wherein the second region has a volume at least 10 times a volume of the first region.
