A demonstration of structured-illumination-based technique using commercial surgical endoscope

Area of Science:

• Medical Imaging
• Surgical Technology
• Biomedical Engineering

Background:

• Accurate three-dimensional (3D) reconstruction is crucial for minimally invasive surgery.
• Existing endoscopic technologies have limitations in depth of field and accuracy for complex biological sample analysis.

Purpose of the Study:

• To integrate a commercial surgical endoscope with structured illumination for enhanced 3D reconstruction.
• To evaluate the system's performance in terms of depth of field and relative accuracy on biological samples.

Main Methods:

• A commercial surgical endoscope was modified and integrated with a structured illumination system.
• Three-dimensional reconstruction algorithms were applied to data acquired from biological samples.
• System performance was quantified by measuring depth of field and relative accuracy.

Main Results:

• The integrated system successfully performed 3D reconstruction of biological samples.
• A depth of field of 20 mm was achieved.
• A relative accuracy of 0.1% was demonstrated.

Conclusions:

• The integration of a commercial surgical endoscope with structured illumination is a viable method for high-accuracy 3D reconstruction.
• This technique offers significant potential for improving visualization and analysis in surgical and biological applications.
