Espy Imaging: Millimeter-scale imaging using structured radio waves

"The most powerful tools in medicine are locked in the least accessible places."

Advanced imaging lives inside hospital walls. It requires million-dollar machines, dedicated facilities, and trained specialists. For the vast majority of the world's patients – in ambulances, clinics, rural settings, conflict zones – these tools simply do not exist.

And when a diagnosis can't reach the patient, neither can the treatment.

Espy Imaging was founded to break that constraint.

Not incremental.
Fundamental.

Orbital angular momentum – the same physics that earned a Nobel Prize in 2014 – applied for the first time to radio-frequency medical imaging. The result: millimeter-scale resolution without ionizing radiation, without contrast agents, without facility-scale infrastructure.

Medical imaging with millimeter resolution using spiraling electromagnetic fields.

UNDERSTAND

Characterize tissue by its electrical properties, not just its shape.

ACT

Deliver targeted energy therapy with real-time, closed-loop guidance.

The physics that allows super-resolution imaging.

In 2014, the Nobel Prize in Chemistry was awarded for super-resolution microscopy using orbital angular momentum. Espy applies the same principle to radio frequencies – creating millimeter-scale RF imaging that didn't exist before.

Step 1

OAM Antenna Transmits

Multi-frequency helical wavefronts carrying orbital angular momentum.

Step 2

Waves Penetrate Tissue

Spiraling fields pass through bone, air, and soft tissue simultaneously.

Step 3

Signals Reflect Back

Returned signals encode conductivity, permittivity, and structural boundaries.

Step 4

AI Reconstruction

Deep learning model solves the inverse problem in seconds.

Step 5

3D Diagnostic Image

Millimeter-resolution tissue map. Anatomy and physiology, in one scan.

Resolution

Millimeter scale via OAM-enhanced RF – previously considered physically impossible at these frequencies.

Safety

Zero ionizing radiation. Unlimited repeat scanning. Completely non-invasive.

Penetration

RF passes through bone, air, and soft tissue – reaching structures ultrasound cannot.

Tissue Characterization

Maps electrical properties (conductivity, permittivity) – a richer diagnostic signal than density alone.

Dual Capability

The same antenna that images can also deliver targeted therapeutic energy – integrated treatment.

Portability

Handheld. Wireless. AI-assisted. Any setting, minimal training required.

Protected IP

Espy Imaging's core technology is protected by 5 granted patents and multiple pending applications, covering the use of orbital angular momentum for medical imaging in the microwave band.

Small team.
Unreasonable ambition.

Espy is built by people who have spent careers at the frontier of what's possible – in biomedical engineering, semiconductor architecture, HealthTech investment, and clinical innovation. They chose this problem because it matters, and because the physics finally make it solvable.

Zvi Or-Bach

Chairman & Co-Founder

Founder and CEO of MonolithIC 3D Inc., a pioneer in monolithic 3D integrated circuit technology. Serial entrepreneur with two successful exits and over 460 patents. Principal inventor of the core technology behind Espy. BSc in Electrical Engineering from the Technion; MSc in Computer Science from the Weizmann Institute.

Espy's strength is multidisciplinary collaboration – bridging deep technical rigor with real-world healthcare experience. The team executes rapidly, advances multiple tracks in parallel, and makes data-driven decisions. Calculated risk is embraced. Mistakes are viewed as part of disciplined innovation, not as failures.

This is not a company that waits for certainty. It is a company that builds toward it.

Espy is not currently advertising open positions, but is always interested in connecting with exceptional people. Scientists, engineers, and clinicians drawn to deep tech, high-impact healthcare, and multidisciplinary R&D are encouraged to reach out through the Contact form below.

The hardest problems demand the broadest thinking.

Espy Imaging was not built in isolation, and it will not scale in isolation. From its earliest days, the company has been shaped by collaboration across disciplines, institutions, and continents. This is not a peripheral strategy – collaboration is the operating model. The physics of OAM imaging live at the intersection of antenna engineering, medical physics, computational electromagnetics, and clinical medicine.

Our collaborations span multiple disciplines at the intersection of electromagnetics, computation, and medical imaging.

  • Advanced antenna engineering and structured electromagnetic fields
  • Metamaterials and wavefront engineering
  • Computational electromagnetics and wave propagation modeling
  • Signal processing and inverse problem reconstruction
  • AI-driven medical image reconstruction

If your research intersects with ours, we want to hear from you.

Let's talk.
