Endoscopic Procedures III: Video Capsule Endoscopy

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: Colonoscopy

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 V: ERCP

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.

Endoscopic Procedures I: Esophagogastroduodenoscopy

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:

Area of Science:

Biomedical Engineering
Medical Imaging
Wireless Communication Systems

Background:

Capsule endoscopy requires efficient data transmission for high-resolution imaging.
Conventional receivers often limit the data rates achievable for capsule endoscope systems.
Higher data rates are crucial for improving image quality and diagnostic accuracy.

Purpose of the Study:

To propose and implement a high-speed receiver for capsule endoscope applications.
To achieve data reception rates of 20 Mbps, surpassing conventional system limitations.
To enable higher-resolution image acquisition for enhanced diagnostic capabilities.

Main Methods:

Utilized a 1.2 GHz band for radio frequency (RF) signal reception.
Demodulated the RF signal to an intermediate frequency (IF) of 150 MHz.
Employed a high-speed analog-to-digital converter (ADC) for signal under-sampling.
Implemented a frequency detection algorithm on a Field-Programmable Gate Array (FPGA) for real-time data decoding.

Main Results:

Successfully implemented a high-speed receiver system capable of receiving 20 Mbps data.
The achieved data rate is sufficient for higher-resolution image transmission compared to conventional receivers.
The real-time decoding of under-sampled data was demonstrated using the FPGA implementation.

Conclusions:

The developed high-speed receiver meets the data rate requirements for advanced capsule endoscopy.
The system's architecture, including under-sampling and FPGA-based decoding, is effective for real-time processing.
This technology has the potential to significantly enhance the diagnostic performance of capsule endoscopes.
