Core Technique

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:
- Radiopharmaceutical uptake (standard PET)
- 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
- Tissue Characterization: Entanglement degree as novel diagnostic biomarker
- Radiopharmaceutical Tracking: Simultaneous uptake + entanglement imaging
- Quality Control: Verify quantum properties of PET sources
Design Principles
- Plastic scintillators enable Compton-based polarization measurement
- Entanglement provides additional diagnostic dimension beyond standard PET
- Quantum effects measurable at clinically relevant activities
- Opens new perspectives for quantum-enhanced clinical diagnostics
