KAIST Spinout · Portable Specimen CT

The Answer in the Room.

MarginX is a portable CT scanner in development, designed to turn an excised surgical specimen into a 3D margin view in 6 minutes — right there in the operating room, before the next step in surgery is decided.

6-Minute Answer

The problem

The question was never whether you removed it. It’s whether the margin is clear.

In breast-conserving surgery, that answer usually isn’t known until well after the patient has left the table — because it’s hard to tell, mid-surgery, whether cancer remains at the edge of what was removed.

Today — off-site pathology

  1. 1
    Excise specimen

    Tissue is removed and placed in transport.

  2. 2
    Send to pathology

    Specimen leaves the room for imaging or sectioning elsewhere.

  3. 3
    Wait for a result

    Frozen section analysis can take 15–60 minutes depending on complexity, and 2D imaging still can't show margin depth.

  4. 4
    Reoperate, if needed

    A positive margin found later can mean a second procedure entirely.

With MarginX — in the room

  1. 1
    Excise specimen

    No change to the surgical step itself.

  2. 2
    Scan, table-side

    MarginX captures a full 3D volume without leaving the room.

  3. 3
    Get the answer

    A reconstructed 3D margin view is ready for the surgeon in 6 minutes.

  4. 4
    Close, with confidence

    Act on the imaging before the patient leaves the table — the specimen still goes to pathology as usual.

10–25%

Published studies put the reoperation rate for positive margins after breast-conserving surgery in roughly this range — on top of the hundreds of thousands of these procedures performed in the U.S. each year. Range reflects published surgical literature on BCS reoperation rates; CorbiT has not conducted an independent epidemiological study.

The product

MarginX

A portable CT scanner engineered to move CT-quality specimen imaging from the pathology suite to wherever the answer is needed.

CT-grade imaging, small enough for the OR

  • 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 (pending clinical validation).
  • Shielded chamber design — patent pendingA proprietary shielding approach, so MarginX is designed to avoid needing a dedicated lead-lined room.
  • Built for speedFrom scan to a 3D margin answer in 6 minutes.
