Conformal antenna-based wireless telemetry system for capsule endoscopy
Capsule endoscopy for imaging the gastrointestinal tract is an innovative tool for carrying out medical diagnosis and therapy. Additional modalities beyond optical imaging would enhance current capabilities at the expense of denser integration, due to the limited space available within the capsule. …

Using ultrasound as a communication scheme for wireless capsule endoscopy
Wireless capsule endoscopy (WCE) has been established as an alternative to traditional video endoscopy because it has several advantages over traditional methods. For example, it can ameliorate the suffering of patients as it does not need intubation, and it can examine the whole small intestine, …

The Detection of Gastrointestinal Inflammation with Microultrasound and The Feasibility of Ultrasound Capsule Endoscopy
… improvements can be met by augmenting capsule endoscopes with microultrasound. Microultrasound (µUS) frequencies are > 20 MHz and have the potential to provide highly detailed transmural images of the bowel wall. This would provide capsule endoscopes with a means of detecting and …

Capsule endoscopy versus standard of care in obscure gastrointestinal bleeding: A randomized controlled trial
… usually involves performing a bidirectional endoscopy. When negative, the small bowel could be the source of obscure gastrointestinal bleeding presenting as IDA. The next best diagnostic test is uncertain. Wireless capsule endoscopy (WCE) is a non-invasive new technology that allows …

Factors governing gastrointestinal motility
… GI motility with alternative methods including capsule endoscopy and hydrogen breath test. Subsequent to this I measured changes in GI motility in two very different patient cohorts; one following bariatric surgery for morbid obesity and the other a group of patients with proven gastroparesis …

AUTOMATIC PATTERN CLASSIFICATION AND STEREOSCOPIC VISION IN MEDICAL IMAGING
… Automatic Classification of Frames from Wireless Capsule Endoscopy and Depth Estimation in Bronchoscopic Intervention . In both cases the exploration of tubular internal structures of the human body through the analysis of endoscopic images asks for innovative and smart algorithms to translate the …

Investigation and development of titanium nitride solid-state potentiometric pH sensor
… potentially used as miniature pH sensors for capsule endoscopy and ambulatory esophageal pH monitoring. To address these issues of limitations of glass electrodes, various metal oxides have been investigated and proposed as potential electrode materials for the development of pH sensors. Solid …

Capsule-based Ultrasound-mediated Targeted Drug Delivery
Over the last 20 years, capsule endoscopy (CE) has emerged as an important clinical tool for the diagnosis of gastrointestinal (GI) diseases such as Crohn’s disease. Despite the success of CE for diagnosis, there has been minimal progress in advancing therapeutic CE (TCE). Targeted drug delivery …

Design, analysis and trajectory tracking control of underactuated mobile capsule robots.
The research on capsule robots (capsubots) has received attraction in recent years because of their compactness, simple structure and their potential use in medical diagnosis (e.g. capsule endoscopy), treatment and surgical assistance. The medical diagnostic capability of a capsule endoscope - …

System Level Approach towards Intelligent Healthcare Environment
… are: locomotion mechanism for wireless capsule endoscope (WCE), multifunctional image guided surgical (MIGS) platform, shape memory alloy (SMA) thermal energy harvester and thermo-acoustic sonar using carbon nanotube (CNT) sheets. First, two types of locomotion mechanisms were developed, …
