# Quantum Entanglement PET Imaging Methodology

## Core Technique
**Source**: arXiv:2606.29421 - "First-in-human quantum entanglement imaging"
**Source**: arXiv:2606.25804 - "Positron Emission Tomography with quantum-entangled Compton events"

## Key Innovation
Annihilation photons from positron-electron annihilation are quantum-entangled in polarization. This entanglement can be measured via Compton scattering to produce simultaneous images of:
1. Radiopharmaceutical uptake (standard PET)
2. Degree of quantum entanglement (novel biomarker)

## Implementation Pattern
- **Hardware**: Plastic scintillators (J-PET scanner) - Compton-effect dominant
- **Measurement**: Simultaneous photon position, time, AND polarization plane
- **Entanglement Metric**: Relative angle between polarization planes of annihilation photon pairs
- **Results**: Liver/spleen entanglement values between maximally entangled and separable states

## Clinical Applications
1. **Tissue Characterization**: Entanglement degree as novel diagnostic biomarker
2. **Radiopharmaceutical Tracking**: Simultaneous uptake + entanglement imaging
3. **Quality Control**: Verify quantum properties of PET sources

## Design Principles
1. Plastic scintillators enable Compton-based polarization measurement
2. Entanglement provides additional diagnostic dimension beyond standard PET
3. Quantum effects measurable at clinically relevant activities
4. Opens new perspectives for quantum-enhanced clinical diagnostics
