20090036743 | MEDICAL APPARATUS - A medical apparatus includes: a first illumination window through which a first illumination light from a first light source is irradiated to a subject; a second illumination window at different position than the first illumination window, through which a second illumination light from a second light source is irradiated to the subject; an electronic image pickup section which picks up subject images; an image creation section which generates observation images based on image pickup signals obtained by the electronic image pickup section; a light adjustment section which synchronously adjusts respective amounts of illumination lights irradiated from the first and second illumination windows; and a control unit which controls the light adjustment section or image creation section to maintain color tone of the observation image to a predetermined one according to increase/decrease of the illumination light amount from the first illumination window. | 02-05-2009 |
20090123043 | Method and System for Correlating Image and Tissue Characteristic Data - Capsule type endoscopes generate large amounts of in-vivo image data that requires review and analysis by a doctor or clinician. By not reviewing the images gathered from healthy tissue, and only focusing on images indicating potential abnormalities, the time it takes to review the data can be greatly reduced. By correlating the tissue images with a characteristic known to indicate a potential abnormality, only the suspect images need to be reviewed. | 05-14-2009 |
20090124853 | Capsule Blood Detection System and Method - A capsule for determining the blood content of living tissue in vivo in a patient to detect tumors. The capsule includes a light source and a light detector for directing light onto the tissue and for receiving interacted light therefrom. By analyzing the interacted lights a determination can be made of the blood content of that tissue. There are various ways of positioning the capsule so that it contacts the tissue in the desired orientation of the light source and light detector. There is also a system for determining the actual contact between the capsule and the tissue. A calibration system is also used that allows a self calibration that can be carried out easily and accurately just prior to the use of the capsule. | 05-14-2009 |
20090124874 | Blood Content Detecting Capsule - A capsule employing components for detecting blood content or hemoglobin concentration within tissue forming a lumen in vivo advantageously permits screening or diagnosis of certain diseases. In one embodiment, the capsule includes a light source for intermittently illuminating a region of tissue and a light detector for receiving interacted light from the tissue and hemoglobin therein. Methods of validating data of interacted light signal are also disclosed. A power conservation method of detecting the blood content values at different rates is further disclosed. | 05-14-2009 |
20090306522 | Method and Apparatus for Detecting Abnormal Living Tissue - Light scattering and absorption techniques for the detection of possible abnormal living tissue. Apparatus and methods for utilizing multiple blood content detection sensors and/or contact sensors for beneficially providing data to better guide an endoscope or colonoscope to locate abnormal tissue, tumors, or tissues that precede the development of such lesions or tumors. | 12-10-2009 |
20100004520 | Method and Apparatus for Foreign Matter Detection For Blood Content Sensors - Apparatus and methods for detecting and removing foreign matter on an in vivo blood content sensor window utilizing time and wavelength techniques to provide more beneficial information to an operator to facilitate for more accurate blood content readings. | 01-07-2010 |
20100005850 | CALIBRATION METHODS FOR BLOOD CONTENT SENSORS - Methods for calibrating blood content sensors used independently or in conjunction with medical instruments such as traditional or capsule type endoscopes. | 01-14-2010 |
20100329520 | Method and System for Correlating Image and Tissue Characteristic Data - Capsule type endoscopes generate large amounts of in-vivo image data that requires review and analysis by a doctor or clinician. By not reviewing the images gathered from healthy tissue, and only focusing on images indicating potential abnormalities, the time it takes to review the data can be greatly reduced.

20110128091 | COUPLER - The invention provides couplers that are thinner and smaller in size and still satisfy the required various properties of the couplers. | 06-02-2011 |
20110273548 | CAPSULE ENDOSCOPE DEVICE - A capsule endoscope device includes an illumination unit that illuminates a living tissue using at least one of a white light illumination unit and a special light illumination unit; an imaging unit that captures an image of the tissue; a transmission unit that transmits imaging information containing the image; a storage unit that stores a threshold with respect to information on a distance between the endoscope and the tissue; a detection unit that detects the information; and an output unit that compares the information with the threshold, selects an image capturing condition of a special light observation mode if the distance is not larger than the threshold, selects an image capturing condition of a normal light observation mode if the distance is larger than the threshold, and outputs the selected image capturing condition to an operation unit related to image capturing. | 11-10-2011 |
20120120487 | ENDOSCOPE AND ENDOSCOPE APPARATUS - An endoscope includes: a first illumination optical system which emits illuminating light in a first linear polarization direction to an object from a distal end face of an insertion portion; and a first objective optical system which allows return light from the object to enter through an objective window provided in the distal end face; wherein the first illumination optical system and the first objective optical system are placed in a positional relationship such that on the distal end face, a line segment connecting an optical axis of the first illumination optical system and an optical axis of the first objective optical system is parallel or perpendicular to a polarization direction which results when the illuminating light emitted from the first illumination optical system is projected to the distal end face, and no polarizing element is provided between the object and the objective window. | 05-17-2012 |
20140176692 | Endoscope System - An image with an expanded depth of field is more effectively acquired while reducing the manufacturing cost, without enlarging the apparatus. | 06-26-2014 |
20140198194 | Endoscope - An endoscope includes an objective optical system at a distal end of an inserted portion to acquire a subject image; a part that splits the subject image into two optical images focused differently; an imaging device that acquires two images by simultaneously capturing the optical images arranged on an imaging surface; and a part for cutting out at least abutting portions of the optical images on the imaging device, wherein A+B>C+D, where A is half the maximum length of light-receiving regions for the optical images at the imaging surface; where TW is an entry angle at the imaging surface when A is at the maximum image height and d is an optical-path-length difference between the optical images, B=dĂ—tanTW; C is half the length of the light-receiving regions in a direction of the optical images arranged on the imaging surface; and D is a distance between the two light-receiving regions. | 07-17-2014 |
