3. Non linear Linear
High noise Low noise
No processing and processing data
error correction through hardware
and software

7. • Preprocessing
• Filtering
• Reconstruction
• Refinement

8. Scan of whole body

9. Advantages
 Noise and power minimization
 Reliability
 Cost reduction
 Flexibility of interfacing

10. 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
