1. Compton Camera David Scraggs

2. Code Aims Use two detectors in Compton scattering experiment Define cones from Compton interactions; cone surfaces define possible source locations Use intersecting cones to constrict source location Locate radiation sources in 3D space Differentiate between multiple nuclides Find best data analysis methods

3. Compton Scattering Arthur Holly Compton gets Nobel in 1927 for: In which theta is a function of scattered photon energy Determination of photon energies defines a cone on which the source must lie

4. Equation of a Cone Define an arbitrary cone in space A cone is a quadratic surface In Cartesian coordinates the implicit equation is given by; Where the c squared term is the cosine squared of the opening angle

5. General Cone After a great deal of fighting with matlab

6. Rotate Cones Euler rotation matrix defined as

7. Define Specific Cone Opening angle calculation relies upon experimental results from both detectors

8. Merge Cones and Detectors

9. Define Interaction in Space
