Diagnostic optic capsule for Gastrointestinal Tract

Part A

2015

---

The project’s goal is to create a capsule that a person swallows, that performs the

test, and an application that analyzes and displays its results.

The purpose of Part A is to design and develop a two-dimensional prototype of a

wireless disposable device for home use. The device should identify pathologies and

transmit information in real time to a Bluetooth-Android-App.

Self-diagnostic swallow able device for home use which identifies pathologic lesions

in the gastrointestinal track and determines whether a person needs more expensive

intrusive diagnostic procedures.

The project is being developed at the New Technologies Center of Sheba

Medical Center, under the management of Prof. Arie Orenstein.

It is a dual-student project: Part A - Hardware, building Capsule, Part B - Software,

signals processing algorithms and user interface. At the end of the project the two

parts were integrated to a full diagnostic system.

1.Background

Pathological tissue has different optical properties than

normal tissue. These differences can be detected in the

backscattered signal when light is projected on normal

tissue or on abnormalities.

The engineering solution is based on a patent that uses

the spectral characteristics of visible light to identify the

tissue pathology.

By measuring photons returning from the targeted

tissue to the sensors and using proprietary algorithm,

we can identify lesion properties
