    摘要: The present invention relates to a device for determining information relating to a suspected occluding structure. It is described to provide (210) a spectral resolving unit with at least one broadband radiation. The at least one broadband radiation comprises a first broadband radiation acquired from a region of interest within a vascular structure. An occluding structure is suspected to be located within the region of interest and wherein the first broadband radiation is associated with the suspected occluding structure. At least one spectrally resolved data set is determined (220) on the basis of the at least one broadband radiation, wherein the at least one spectrally resolved data set comprises a first spectrally resolved data set determined on the basis of the first broadband radiation. A processing unit is provided (230) with the at least one spectrally resolved data set on the basis of the at least one broadband radiation. The processing unit determines (240) information relating to the suspected occluding structure, comprising utilisation of the first spectrally resolved data set.

    摘要: A medical imaging system for identifying a target structure (TS), e.g. a tumor, in a biological tissue. A hyperspectral camera system is used for imaging a surface area (A1) of the tissue (BT), e.g. with a limited spectral resolution, but enough to allow identification of suspicious areas where the target structure (TS) may be, e.g. such areas can be visually indicated on a display to the operator. A probe (PR), e.g. an optical surface probe, is used to provide probe measurement of a smaller surface area (A2) of the tissue, but with more information indicative of the target structure. The probe is selected to provide a higher specificity with respect to identification of the target structure than the hyperspectral camera (HSC). The hyperspectral processing algorithm (PP) is then calibrated based on probe measurement data performed within the suspicious areas, thus providing a calibrated hyperspectral processing algorithm resulting in images with an enhanced sensitivity to identify the target structure. Only few probe measurements are required to significantly improve the resulting image, thereby providing a reliable and fast target structure (TS) identification.

    摘要: The present invention relates to determining a treatment response index. In order to improve and facilitate hypertension treatment procedures, a device (10) for determining a treatment response index is provided that comprises a data input (12), a data processor (14) and a data output (16). The data input is configured to receive a value (18) of at least one first measurement of a physiological parameter of a subjects vasculature under a first condition; and to provide a value (20) of at least one second measurement of the physiological parameter of the vasculature under a second condition. In the second condition, a pre-determined stimulation is provided, and the first condition is non-stimulated or at least differently stimulated. The data processor is configured to generate a treatment response index. In an example, the data output is configured to provide a classification of the subject into one of at least two groups of subjects, based on the treatment response index.

    摘要: A catheter (12) has an image sensing system (S1-S5) for imaging the interior wall of a passageway in which the catheter is to be located. The catheter has a radial imaging system comprising a light source arrangement for generating a light output radially around the catheter and an image sensor for receiving the generally radial light after the light has been scattered back by the interior wall. The catheter is positioned within the passageway with a known position and orientation, for example a known angle with respect to the anterior-posterior plane along the length of the catheter, so that it is known where along the catheter length, and at which angular position around the catheter, it is close to the passageway wall. The light output has a different intensity at different radial directions and/or the catheter comprises a light transmission arrangement which gives rise to different transmission of the light output at different radial directions. These provide alternative measures to reduce the light received by the image sensor, thereby to prevent blooming in the captured image.
