Technology Overview: Principles and Advances in Microwave Tomography

Microwave tomography (MWT) systems are emerging as a promising imaging modality, leveraging the interaction of low-power microwave signals with biological tissues to reconstruct spatial maps of dielectric properties. The core principle involves transmitting microwaves into a target region and measuring the scattered signals with an array of antennas. These measurements are then processed using advanced algorithms to generate tomographic images, offering a non-ionizing, cost-effective alternative to conventional imaging techniques such as X-ray CT or MRI.

Recent years have seen significant technological advances in both the hardware and computational aspects of MWT systems. Modern systems utilize wideband antennas and multi-channel transceivers to improve spatial resolution and signal-to-noise ratios. The integration of high-speed analog-to-digital converters and field-programmable gate arrays (FPGAs) has enabled real-time data acquisition and processing, a critical step for clinical viability. Companies such as Emblation and Micrima are at the forefront, with Micrima’s MARIA system already deployed in select European clinics for breast cancer imaging, demonstrating the transition from research prototypes to commercial products.

Algorithmic advances are equally pivotal. The ill-posed nature of the inverse scattering problem in MWT has historically limited image quality. However, the adoption of machine learning and deep learning techniques is now enabling more robust and accurate reconstructions, even in the presence of noise and limited data. These computational improvements are expected to further enhance the clinical utility of MWT systems in the coming years.

In 2025, the focus is on expanding clinical validation and regulatory approvals. For example, Micrima continues to collect multi-center clinical data to support broader adoption, while other manufacturers are developing portable and point-of-care MWT devices for applications such as stroke detection and brain imaging. The modularity and scalability of current system architectures are facilitating adaptation to diverse clinical scenarios, from breast imaging to musculoskeletal and brain applications.

Looking ahead, the next few years are expected to bring further miniaturization of hardware, integration with other imaging modalities, and enhanced user interfaces. Industry collaborations with academic and healthcare institutions are accelerating the translation of MWT technology from bench to bedside. As more systems achieve regulatory clearance and demonstrate clinical efficacy, microwave tomography is poised to become a valuable addition to the medical imaging landscape, particularly in settings where safety, portability, and cost are paramount.
