MambaXray-PRB
MambaXray-PRB is a multimodal AI framework for radiology report generation from X-ray images. It employs a three-stage training pipeline comprising pre-training, reasoning, and benchmarking, and integrates multimodal chain-of-thought reasoning to improve report generation performance and interpretability.
Timeline (last 90 days)
An arXiv paper proposes an X-ray radiology report generation framework named MambaXray-PRB and constructs a standardized benchmark.
The research team established a comprehensive benchmark covering mainstream X-ray report generation models and large language models, filling the gap of CheXpert Plus lacking baselines.
The PRB in MambaXray-PRB corresponds to three keywords: Pre-training, Reasoning, and Benchmarking.
The training pipeline of MambaXray-PRB is divided into three consecutive stages: self-supervised autoregressive modeling, X-ray–report contrastive learning, and post-training optimization for reasoning and report generation.
The first stage of MambaXray-PRB pre-trains the model in a self-supervised autoregressive manner to learn low-level representations of X-ray images.
The second stage of MambaXray-PRB introduces contrastive learning between X-ray images and report text, pulling matched image-text pairs closer and pushing mismatched pairs apart.
The third stage of MambaXray-PRB leverages multimodal chain-of-thought for post-training optimization of reasoning and report generation tasks to improve interpretability.
The research team conducted experiments on three datasets—IU X-ray, MIMIC-CXR, and CheXpert Plus—to validate the effectiveness of MambaXray-PRB.
The source code of the paper has been open-sourced on GitHub, with the repository address Event-AHU/Medical_Image_Analysis.
