CDMIQA: A Cross-Domain Perceptual Method and Benchmark Dataset for Medical Image Quality Assessment

摘要

Medical image quality assessment (IQA) serves as a critical safeguard for precise clinical diagnosis and treatment. However, existing methods still face challenges arising from data scarcity and heterogeneity across imaging domains, which confine solutions to domain-specific designs and limit their cross-domain generalization ability. In response, we construct a multi-domain and multi-organ dataset comprising 9,105 2D and 3D medical images across three imaging domains and 18 organs, annotated by radiologists. Building upon this, we propose a cross-domain universal medical IQA method termed CDMIQA, which integrates efficient feature extractors with Hierarchical Perceptual Encoding Modules to capture and refine multi-level perceptual features while mitigating interference from noise and artifacts. Notably, the Adaptive Semantic Perception Module is designed to extract semantic features; it enhances adaptability to domain-specific images by dynamically encoding quality variations across different imaging domains and organs. Furthermore, a Top-down Feature Fusion Module is utilized to progressively aggregate features under the guidance of semantic information, reinforcing the model's feature representation capability. Experimental results on the proposed dataset demonstrate that our method outperforms standard competitors and exhibits superior generalization ability across diverse domains.
