    摘要: The invention relates to a filtering apparatus (15) for filtering an ultrasound signal, which is influenced by an electrical unit and comprises a first part including information about an object (4) from which the ultrasound signal has been received and a second part not comprising information about the object. A correction signal determination unit (17) determines a correction signal being indicative of the influence of the electrical unit on the ultrasound signal from the second part of the ultrasound signal and a correction unit (18) corrects the first part of the ultrasound signal based on the determined correction signal for filtering the influence of the electrical unit out of the ultrasound signal. Since the correction signal is indicative of the influence of the electrical unit, wherein the correction signal is used for correcting the ultrasound signal, unwanted interference visible in the unfiltered ultrasound signal can be filtered out.

    摘要: A sensor probe for detecting an environmental state within a bodily lumen includes an elongated body having an optical guide with an outcoupling surface, which is part of an end surface of the elongated body, facing a reflective surface of an overhanging part. The sensor probe further includes a photodetector which detects a property of light which is composed of light in the optical guide that is reflected from the outcoupling surface of the optical guide and of light in the optical guide that is reflected from the overhanging part. The sensor probe also includes a hydrogel material having a property that changes when getting into contact with an environmental material and/or when detecting an environmental change. The hydrogel material is provided between the end surface of the elongated body and the overhanging part.

    摘要: The invention relates to a biopsy device, particularly a biopsy device comprising a shaft with a transducer element for providing information about acoustic properties of a material to be analysed, a system of positioning a biopsy device and a method for positioning a biopsy device. The biopsy device may be adapted to take biopsies of different regions of the 5 human body for excluding or detecting abnormalities as cancerous lesions. The biopsy device may be used to measure acoustic properties of the material while inserting the tip portion of the biopsy device into the material to be analysed. The biopsy device may further allow measurement based on elastography.
