    摘要： The present invention relates to a blood vessel wall analyzing apparatus provided with a structure enabling accurate measurement of plaque components in a blood vessel wall in a state that reduces the burden on a patient. In the blood vessel wall analyzing apparatus (1), measurement light is illuminated onto a measured portion within a blood vessel such as a carotid artery (C) from a light illuminating unit (30) provided outside the blood vessel, while light from the measured portion is detected in a light receiving unit (40) provided outside the blood vessel. Thus, since the status of the blood vessel wall can be analyzed without inserting an apparatus involved in measurement into the blood vessel, the burden on the patient is reduced during measurement. In addition, as a result of carrying out measurement using near infrared light (a light component in the wavelength range of 780 nm to 2750 nm) that exhibits characteristics that differ according to the compositions of substances such as plaque adhered within the blood vessel, analyses can be carried out that distinguish compositions such as plaque using an analyzing apparatus provided outside the blood vessel.

    摘要： The present application provides a probe positioning technology for disposing a probe (307) at a position, at which an optical bioinstrumentation for living body exhibits high sensitivity, so as to improve positional reproducibility to be ensured at the time of remounting the probe. Moreover, the present application provides an optical bioinstrumentation for living body comprising a region selecting unit (305) that is used to delineate a region of interest in an anatomical image of a subject, a computing unit (306) that determines a recommended probe position according to the region of interest, a probe position sensor (308) that detects a current probe position, a computing unit (306) that calculates the distance between the recommended probe position and the current probe position, and an alarm device (314) that generates an alarm sound or the like when the distance falls within a predetermined range. Moreover, the optical bioinstrumentation for living body comprises a memory unit (303) in which the probe position is saved together with measurement data. Herein, a previous probe position is regarded as a recommended probe position in order to determine a probe position.

    摘要： A method of acquiring a graphic prescription from an operator of an imaging device comprises displaying a first two-dimensional view of a first localizer image (202, 204, 206) and a second two-dimensional view of a second localizer image (202, 204, 206), and displaying a three-dimensional view of the first and second localizer images (202, 204, 206). The first and second two-dimensional views of the first and second localizer images (202, 204, 206) are displayed in first and second viewing regions (201, 203, 205) of a graphic prescription interface (200, 300). The three-dimensional view shows the first and second localizer images (202, 204, 206) relative to each other in overlapping fashion in a common viewing region (301) of the graphic prescription interface (200, 300). The method also allows a previous prescription to be displayed as a cross reference, and allows a prescription to fallback to any localizer image in a sequence of localizer images.

    摘要： A method and apparatus for imaging teeth (18) includes illuminating a surface of a tooth (18) and electronically imaging the tooth from a non-illuminated surface of the tooth with an electronic camera (24). Automatic control of the intensity of illumination is preferably provided to avoid saturation of the camera. The camera may include a charged-coupled-device (88) and the resulting digital images are preferably enhanced by wavelet analysis. If a video camera is used, the images may be digitized and then enhanced. Current images of the tooth may be compared to prior images of the same tooth to monitor changes in the tooth over time. The images can be used to detect dental caries and other dental conditions. A handpiece (12) for illuminating the tooth and receiving the light passing through the tooth for reception by the camera in a reproducible manner is also described.
