Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Area of Science:

  • Optical Engineering
  • Biomedical Optics
  • Fiber Optics

Background:

  • Speckle contrast in endoscopic imaging reduces image quality and diagnostic accuracy.
  • Efficient signal collection and extended depth of field are crucial for advanced endoscopic visualization.
  • Current fiber optic solutions for endoscopy face limitations in performance and versatility.

Purpose of the Study:

  • To develop and characterize a double-clad fiber coupler (DCFC) for endoscopic applications.
  • To improve speckle reduction, signal collection efficiency, and depth of field in endoscopic imaging.
  • To demonstrate the capability of the DCFC for combined reflectance imaging and depth profiling.

Main Methods:

  • Fabrication of the DCFC by fusing and tapering two all-silica double-clad fibers (DCF).
  • Characterization of achromatic transmission efficiency for core illumination (1265nm - 1325nm).
  • Evaluation of inner cladding diffuse light collection efficiency.
  • Demonstration in a spectrally encoded imaging setup for endoscopy.

Main Results:

  • Achieved >95% achromatic transmission of core illumination and >42% collection of inner cladding diffuse light.
  • Demonstrated a 5x reduction in speckle contrast.
  • Showcased a 9x increase in signal collection and a 1.8x enhancement in depth of field.
  • Successfully separated single- and multi-mode signals for combined imaging modalities.

Conclusions:

  • The developed DCFC significantly enhances endoscopic imaging performance.
  • The DCFC enables high-quality, low-speckle 3D imaging through an all-fiber, low-loss instrument.
  • This technology holds promise for advanced diagnostic and interventional endoscopy.
