Microwave technology for localization of traumatic intracranial bleedings-a numerical simulation study

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Computational Neuroscience

Background:

• Traumatic brain injury (TBI) is a significant global health concern.
• Intracranial bleeding is a critical complication of TBI requiring prompt surgical intervention.
• Current diagnostic methods like CT scans have limitations in pre-hospital settings.

Purpose of the Study:

• To evaluate the potential of microwave technology (MWT) for early detection and localization of intracranial bleedings.
• To assess the efficacy of a classification algorithm based on singular value decomposition (SVD) for differentiating bleeding locations.

Main Methods:

• Numerical simulations were conducted to model simplified scenarios of intracranial bleeding.
• A classification algorithm utilizing singular value decomposition was applied to simulated data.
• The algorithm's ability to distinguish bleedings at various positions near the skull bone was tested.

Main Results:

• The classification algorithm achieved high accuracy, ranging from 94% to 100% across different bleeding location classes.
• Simulations demonstrated the potential of MWT to differentiate bleeding positions adjacent to the skull bone.
• The findings support the feasibility of using MWT for bleeding localization.

Conclusions:

• Microwave technology, combined with SVD-based classification, shows significant potential for the early detection and localization of intracranial bleedings.
• This technology could enhance diagnostic capabilities in pre-hospital emergency care, such as in ambulances.
• Further research into more realistic scenarios is warranted to advance MWT for TBI management.
