Disclosed is a medical image processing device for generating an image in which a difference in color between an abnormal part where a gastric mucosa is atrophied, and a normal part is enhanced.

A B/G ratio is determined from B and G image signals, and a G/R ratio is determined from the G and R image signals. In a feature space formed from the B/G ratio and the G/R ratio, first processing is performed for moving the coordinates of a second range to a reference range including the origin in a state where the coordinates of first and third ranges are maintained. In order to make the first range and the third range distant from each other, second processing is performed for moving the first and third ranges. A first special image is generated based on the B/G ratio and the G/R ratio after the first and second processing.

Systems and methods are provided for performing optical coherence tomography (OCT) angiography for the rapid generation of en-face images. According to one example embodiment, differential interferograms obtained using a spectral domain or swept source OCT system are convolved with a Gabor filter, where the Gabor filter is computed according to an estimated surface depth of the tissue surface. The Gabor-convolved differential interferogram is processed to produce an en-face image, without requiring the performing of a fast Fourier transform and k-space resampling. In another example embodiment, two interferograms are separately convolved with a Gabor filter, and the amplitudes of the Gabor-convolved interferograms are subtracted to generate a differential Gabor-convolved interferogram amplitude frame, which is further processed to generate an en-face image without performing a fast Fourier transform and k-space resampling. The example OCTA methods disclosed herein are shown to achieve faster data processing speeds compared to conventional OCTA algorithms.

The present invention provides an improved breath analyzer and breath test method to determine the presence of disease in humans, including but not limited to, the bacterium H. pylori in a subjects digestive tract. In certain embodiments, the present invention provides a universal breath testing platform and methods of testing for diseases of the gastrointestinal tract, the liver, the kidneys, and the lungs, along with testing for cancer, infections, and metabolic diseases.

Systems and methods that can employ a bleeding sensor that uses an optical mechanism to detect blood in the patients GI tract are described. The bleeding sensor includes a substrate holding a centrally-located light detector with a broad sensitivity spectrum and at least two light emitters positioned radially around the centrally-located light detector, each light emitter configured to emit light of different primary wavelengths. The bleeding sensor has a gap between each of the at least two light emitters and the centrally-located light detector that accepts the contents of a patients gastrointestinal tract. An optical cap covers the centrally-located light detector and the at least two light emitters to direct the light emitted from the at least two light emitters through the gap and onto the centrally-located light detector.
