Abstract
Gamma cameras are provided. The subject gamma cameras include an analysis region comprising a spatial area configured to receive a sample, a first detector head positioned to receive gamma radiation from the analysis region, the first detector head including a first scatterer and a first absorber parallel to the first scatterer, and a second detector head positioned on the opposite side of the analysis region relative to the first detector head, the second detector head including a second scatterer and a second absorber parallel to the second scatterer. Systems and methods for practicing the invention are also provided.
Claims69
A gamma camera comprising:

- a first detector head positioned to receive gamma radiation from the analysis region, the first detector head comprising a first scatterer and a first absorber parallel to the first scatterer;
- and
- a second detector head positioned on the opposite side of the analysis region relative to the first detector head, the second detector head comprising a second scatterer and a second absorber parallel to the second scatterer.
The gamma camera according to any of the preceding claims, wherein the first and second absorbers are semiconductor detectors.
The gamma camera according to any of the preceding claims, wherein the first scatterer is positioned between the first absorber and the analysis region.
The gamma camera according to any of the preceding claims, wherein the second scatterer is positioned between the second absorber and the analysis region.
The gamma camera according to any of the preceding claims, wherein the first scatterer is separated from the second scatterer by a distance ranging from 20 mm to 40 mm.
The gamma camera according to any of the preceding claims, wherein first scatterer is separated from the first absorber by a distance ranging from 10 mm to 40 mm.
