All fiber based multispeckle modality endoscopic system for imaging medical cavities

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Optical Engineering

Background:

• Early detection of colon abnormalities is crucial for effective treatment.
• Existing endoscopic methods may have limitations in sensitivity and specificity.
• Novel imaging techniques are needed to improve disease detection in body cavities.

Purpose of the Study:

• To develop and evaluate a novel fiber-optic multispeckle modality endoscopic system for disease detection in body cavities.
• To assess the system's effectiveness in identifying abnormal growths in the colon.
• To demonstrate an all-fiber-optic approach for illumination and imaging within internal body cavities.

Main Methods:

• Designed and fabricated a custom endoscope probe with integrated illumination fibers and an imaging lens-image fiber unit.
• Utilized a fiber-optic approach for illumination and imaging of inner cavity walls.
• Employed optical elements like beam combiners and biprisms for direction-sensitive configurations.
• Conducted experimental investigations using a colon phantom model with normal and abnormal regions.

Main Results:

• The developed endoscopic system demonstrated effectiveness in identifying abnormal growths.
• The multispeckle modality enabled early-stage detection of simulated colon abnormalities.
• The all-fiber-optic design facilitated comprehensive imaging of the colon's inner surface.

Conclusions:

• The fiber-optic multispeckle endoscopic system is a promising tool for early disease detection in the colon.
• This technology can significantly aid in the early diagnosis of abnormal growths.
• The custom-designed endoscope probe and optical configurations enable sensitive and direction-aware imaging.
