A Back Projection Method for Hexagonal Coding Collimators in Emission Tomography with Multiplexed Measurement Systems
- 14 Downloads
Computerized emission tomography is an effective method for the diagnosis of pathological states in the human body. A new emission tomography approach was developed involving the use of multiplexed measurement systems (MMS). An iterative algorithm implementing the back projection method for emission tomography based on MMS was developed using hexagonal coding collimators. Numerical modeling demonstrated the validity of the proposed method.
