The technology
How MarginX turns a specimen into an answer.
A portable cone-beam CT, a patent-pending shielded chamber design, and a 3D reconstruction pipeline built around one goal: a margin answer before the patient leaves the table.
How it works
Three steps, one room.
MarginX is designed around a single sequence: position the specimen, scan it, and read the answer — without ever leaving the table.
Position
Place the specimen on the scan pad, right at the table — no transport, no waiting for a slot in imaging.
Scan
MarginX rotates through a full cone-beam CT acquisition in a single pass, capturing the whole specimen volume.
Answer
A reconstructed 3D margin view renders for the surgical team — 6 minutes after the scan starts.
Inside MarginX
CT-grade imaging, small enough for the OR
The core engineering bet behind MarginX: a specimen CT doesn't need a shielded room or a 100 kg gantry to deliver a real 3D answer.
Concept renderings — MarginX is in active R&D; final hardware form factor, software UI, and labeling may change.
Four engineering decisions, one outcome
-
Portable, roughly 20 kgComparable specimen CT systems run 80–120 kg and simply can't be brought into an operating room.
-
True 3D reconstructionDesigned to pinpoint where a lesion sits relative to the resection margin, down to fine calcifications, not just whether one is present (pending clinical validation).
-
Shielded chamber design — patent pendingA proprietary shielding approach, designed to avoid needing a dedicated lead-lined room or special power supply.
-
Built for speedFrom scan to a 3D margin answer in 6 minutes.

How it compares
Where MarginX sits against today's options
| Method | Dimensionality | Time to result | Tissue impact | Room requirements |
|---|---|---|---|---|
| 2D Specimen X-ray | 2D projection | Minutes | Non-destructive | Standard OR |
| Frozen Section Analysis | 2D section | 15–60 minutes, depending on blocks | Sections tissue; can affect permanent histology | On-site pathology lab |
| MarginX | Full 3D volume | ~6 minutes | Non-destructive | Standard OR — no shielded room |
MarginX is designed as an adjunct to, not a replacement for, permanent histopathology — the specimen still proceeds to pathology as usual after scanning.
Why it matters
Not a smaller X-ray. A different question, answered.
Two-dimensional specimen radiography can miss what a margin actually looks like in three dimensions. That gap is the one MarginX is built to close.
3D, not 2D
Volumetric imaging surfaces margin depth that flat radiography can't show.
Designed to skip the shielded room
A proprietary shielded chamber design (patent pending) is intended to avoid the need for a dedicated lead-lined room or special power.

Engineered for speed
Every design decision is weighed against one question: does it save time in the room?
