A novel intelligent chromo capsule endoscope for the diagnosis of neoplastic lesions in the gastrointestinal tract.

Background: Chromoendoscopy has not been fully integrated into capsule endoscopy. This study aimded to develop and validate a novel intelligent chromo capsule endoscope (ICCE).

Methods: The ICCE has two modes: a white-light imaging (WLI) mode and an intelligent chromo imaging (ICI) mode.

Novel scheme for non-invasive gut bioinformation acquisition with a magnetically controlled sampling capsule endoscope.

Objective: Intestinal flora and metabolites are associated with multiple systemic diseases. Current approaches for acquiring information regarding microbiota/metabolites have limitations. We aimed to develop a precise magnetically controlled sampling capsule endoscope (MSCE) for the convenient, non-invasive and accurate acquisition of digestive bioinformation for disease diagnosis and evaluation.

Spectral unmixing method for multi-pixel energy dispersive x-ray diffraction systems.

An algorithm of spectral unmixing (SU) is presented, allowing the improvement of material classification accuracy based on the low spatial resolution images obtained by multi-pixel energy dispersive x-ray diffraction (EDXRD) systems. The method, which consists of signal subspace identification and endmember extraction, performs well even when the pixel count is rather small. Combined with SU, EDXRD has been utilized for liquid security screening for the first time.

Determination of liquid's molecular interference function based on X-ray diffraction and dual-energy CT in security screening.

A method for deriving the molecular interference function (MIF) of an unknown liquid for security screening is presented. Based on the effective atomic number reconstructed from dual-energy computed tomography (CT), equivalent molecular formula of the liquid is estimated. After a series of optimizations, the MIF and a new effective atomic number are finally obtained from the X-ray diffraction (XRD) profile.
