Linear
Low noise
processing data through hardware and software
• Preprocessing
• Filtering
• Reconstruction
• Refinement
Scan of whole body
Advantages
Noise and power minimization
Reliability
Cost reduction
Flexibility of interfacing
Conclusion
A digital acquisition system for gamma camera is presented
The system consists of the detection module with
Front end ASIC that feeds the presented digital system and a host PC where data processing and image reconstruction is performed
By using Digital acquisition system in Gamma camera results better and clear image output
