Fujifilm X-ray Patent Enables Real-time 3D Tool Tracking
Summary
USPTO granted patent US12599347B2 to FUJIFILM Corporation on April 14, 2026, for an X-ray imaging apparatus enabling real-time 3D position tracking of treatment tools during medical operations. The system uses two X-ray tubes—one stationary and one rotating along a circular orbit—to calculate three-dimensional tool positions without rotating the tube column. The patent names Isao Takahashi, Kazuki Matsuzaki, Keisuke Yamakawa, and Tadashi Nakamura as inventors.
“Provided is an X-ray imaging apparatus that can understand a three-dimensional position of a treatment tool in real time during a medical operation without rotating a column of an X-ray tube.”

What changed
USPTO granted patent US12599347B2 to FUJIFILM Corporation on April 14, 2026, covering an X-ray imaging apparatus that calculates three-dimensional tool positions in real time during medical operations. The system employs a stationary first X-ray tube and a second X-ray tube that moves rotationally along a circular orbit, using dual X-ray images to triangulate the position of predetermined feature parts.
Medical device manufacturers developing intraoperative imaging or surgical navigation systems should note this patent's approach to avoiding mechanical complexity. The ability to perform 3D tracking without rotating the tube column may offer design alternatives for fluoroscopy-based procedures.

Abstract
Provided is an X-ray imaging apparatus that can understand a three-dimensional position of a treatment tool in real time during a medical operation without rotating a column of an X-ray tube. A first X-ray tube is disposed at a position at which a target part of a subject placed on a top plate is irradiated with X-rays, and a second X-ray tube is disposed by causing the second X-ray tube to move rotationally along a circular orbit about an axis connecting the first X-ray tube and the top plate. A first X-ray image is acquired by irradiating the subject with the X-rays from the first X-ray tube. A second X-ray image is acquired by irradiating the subject with X-rays from the second X-ray tube. A position of an image of a predetermined feature part included in the first X-ray image and a position of an image of the feature part included in the second X-ray image are used to calculate a three-dimensional position of the image of the predetermined feature part.
