Background:

Hemorrhagic stroke is a critical condition requiring rapid diagnosis.
Microwave imaging offers a portable, non-ionizing alternative for stroke screening.
Current single-modality methods face limitations in resolution and data utilization.

Purpose of the Study:

To develop an advanced deep learning model for improved hemorrhagic stroke recognition.
To leverage multimodal data for enhanced diagnostic capabilities.
To overcome limitations of single-modality microwave imaging.

Main Methods:

A dual-channel, multi-input multimodal deep neural network was designed.
The model integrates features from microwave images and time-domain waveforms.
A high-fidelity simulated brain dataset was used for training and evaluating temporal encoding strategies.

Main Results:

The multimodal model demonstrated superior accuracy and stability over single-modality approaches.
Feature-level cross-modal fusion significantly benefited microwave-based hemorrhage recognition.
The proposed method shows enhanced discrimination and robustness.

Conclusions:

Multimodal learning improves the performance of microwave-based hemorrhage detection.
This approach supports the development of rapid, non-ionizing tools for pre-hospital and bedside stroke assessment.
The findings highlight the potential of AI in cerebrovascular disease diagnostics.
