A Flexible Hybrid Quantum-classical Training Framework of Organ-at-Risk and Tumor Segmentation Models for Radiation Therapy Planning
This paper introduces a Hybrid Quantum-Classical Training Framework (HQC-TF) for organ-at-risk (OAR) and tumor segmentation in radiation therapy planning. Addressing over-parameterization in small-sample medical settings, HQC-TF leverages Quantum Parameter Generation (QPG) with independent Variational Quantum Circuits (VQCs) to reduce trainable parameters while preserving model structure and adaptive rank determination. Experiments demonstrate significant segmentation improvements, e.g., UNetPP gained 6.77% IoU for kidney tumors, using fewer parameters and operating only during training, making it a practical solution for near-term clinical use.

Methodology
The research delves into a Hybrid Quantum-Classical Training Framework (HQC-TF) designed for robust and parameter-efficient medical image segmentation. It introduces a Quantum Parameter Generation (QPG) technique leveraging independent Variational Quantum Circuits (VQCs) to generate neural network parameters, thus reducing the total number of trainable parameters significantly. This approach avoids the limitations of traditional parameter reduction methods, such as fixed rank approximations, by adaptively determining parameter matrices’ ranks during training. Key contributions include novel convolutional layers (QPGConv and QPGAConv) that minimize qubits while preserving channel independence and inherently performing weight normalization. The framework's design allows for flexible integration into existing deep neural networks, making it scalable and practical for near-term clinical use in radiation therapy planning.

Quantum-Classical Hybridization for Medical Image Segmentation
The study successfully applies a hybrid quantum-classical training framework (HQC-TF) to medical image segmentation, a domain critical for radiation therapy. By integrating Quantum Parameter Generation (QPG) into deep learning models, HQC-TF addresses the common issue of over-parameterization when dealing with small, labeled datasets. This approach not only significantly reduces the number of trainable parameters but also enhances segmentation performance, particularly for complex tasks like kidney tumor delineation. The framework’s ability to operate during the training phase using shallow quantum circuits makes it highly practical for near-term clinical translation, offering a pathway to more efficient and accurate AI in healthcare.
- Reduced parameter counts lead to less overfitting in small datasets.
- Improved segmentation accuracy for both OARs and tumors.
- Maintains channel independence, crucial for feature extraction.
- Practical for NISQ-era quantum hardware due to shallow circuits.
