X-ray Imaging

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Area of Science:

Medical Imaging
Surgical Navigation
Biomedical Engineering

Background:

Electromagnetic tracking (EM) is crucial for minimally invasive surgery, often used with X-ray technology.
Conventional EM systems cause X-ray artifacts and attenuation due to radiopaque materials.
Existing systems limit the clarity of intraoperative imaging.

Purpose of the Study:

To develop a novel radiolucent electromagnetic navigation system.
To minimize the impact of EM tracking on X-ray imaging.
To improve the integration of EM tracking and X-ray diagnostics in surgery.

Main Methods:

Developed a new electromagnetic navigation system using radiolucent materials.
Replaced traditional dense materials (copper, steel) in EM coils with low-density aluminum.
Continued development of the Anser open-source electromagnetic tracking system.

Main Results:

Achieved at least a 60% reduction in X-ray attenuation compared to previous designs.
Demonstrated significantly reduced impact on X-ray images.
Maintained system accuracy with approximately 1.5 mm RMS error.

Conclusions:

The novel radiolucent electromagnetic navigation system effectively reduces X-ray artifacts.
This advancement enhances the utility of EM tracking in conjunction with X-ray imaging for surgical navigation.
The improved system offers better image clarity without compromising tracking precision.
