    摘要： The present invention relates to an acoustic device for ultrasonic imaging of an object (21). The device comprises an acoustic transducer (10 and an acoustic lens (20) arranged to variably refract the said acoustic pulse to and/or from the acoustic transducer. The acoustic lens comprising a first (L1) and a second fluid (L2) being separated by an acoustic interface (7), the normal of the said acoustic interface forming a relative angle of incidence (AI) with the said acoustic pulse, e.g. an electrowetting lens. The first and the second fluid of the acoustic lens (20) are specifically chosen so that the acoustic interface (7) has a reflection minima at a non-zero relative angle of incidence (AI). The invention is advantageous for obtaining an improved acoustic device having a substantially lower reflection in a broader interval of incidence angles as compared to hitherto seen ultrasonic imaging utilising acoustic lenses with two or more fluids as the active acoustic refracting entities.

    摘要： An acoustic probe includes an acoustic transducer having acoustic transducer elements arranged in a one-dimensional array; and a variably-refracting acoustic lens coupled to the acoustic transducer. The variably-refracting acoustic lens has a pair of electrodes configured to adjust the focus of the variably-refracting acoustic lens in response to a selected voltage applied across the electrodes. In one embodiment, the variably-refracting acoustic lens includes a cavity, first and second fluid media disposed within the cavity, and the pair of electrodes. The speed of sound of an acoustic wave in the first fluid medium is different than the speed of sound of the acoustic wave in the second fluid medium. The first and second fluid media are immiscible with respect to each other, and the first fluid medium has a substantially different electrical conductivity than the second fluid medium.

    摘要： Fluid lens system, e.g. for medical imaging or medical treatment, with a container enclosing a fluid arranged to refract incoming waves. A pressure release mechanism is in contact with the fluid so as to compensate changes in its volume due to thermal variations, e.g. during high temperature medical cleaning. This pressure release mechanism is positioned within a pathway of incoming waves. In preferred embodiments a fluid container connected via a tube to the fluid as a reservoir, is arranged within or outside the container, e.g. beyond an image sensor. Alternatively, an easily compressible body, e.g. a small closed metal bellows enclosing a gas, is positioned inside the fluid to absorb volume changes by compression. In both embodiments, the pressure release elements are preferably positioned in a peripheral part of the pathway of incoming waves to not affect performance of the lens. In another aspect, a fluid lens includes a container with an inner container part that fits inside an outer container part, wherein the inner container part is in rigid connection to at least a one boundary arranged for penetration of incoming waves. The pressure release mechanism is positioned within the outer container part, and it is in contact with the fluid so as to compensate changes in volume of the fluid due to thermal variations. In one embodiment the inner and outer container parts are arranged for relative one-dimensional movement and fluid tight interconnected. In another embodiment, a fluid filled cavity is formed between the inner and outer container parts, and this cavity houses a compressible body. The lens systems are suited for applications such as medical endoscopes, catheters and needles, optically as well as acoustically based.

    摘要： The invention relates to a sensor probe (100,110,120,130,140,150) for detecting an environmental state within a bodily lumen. The sensor probe (100,110,120,130,140,150) having an elongated body (9) comprises an optical guide (1) having an outcoupling surface (11), which is part of an end surface (3) of the elongated body (9), facing a reflective surface of an overhanging part (22,42,52,62), a photodetector which detects a property of light which is composed of light (32) in the optical guide (1) that is reflected from the outcoupling surface (11) of the optical guide (1) and of light (33) in the optical guide (1) that is reflected from the overhanging part (22,42,52,62), and a hydrogel material (2) of which a property changes when getting into contact with an environmental material and/or when detecting an environmental change, and which is provided between the end surface (3) of the elongated body (9) and the overhanging part (22,42,52,62). In this way a sensor probe (100,110,120,130,140,150) is provided that, because of its compactness, can be applied inside the bodily lumen for detecting and characterizing parameters that are vital indicators for the state of the human or animal body, and to which the hydrogel material (2) is responsive.

    摘要： In a medical therapy or diagnostic system, magnetic resonance (MR) techniques are used in order to determine the position of the focal point of an ultrasound wave with respect to a patient's body. Therefore, it is an object of the present invention to provide an ultrasound waveguide which could be used within a magnetic resonance environment. To better address these concerns, it is an aspect of the present invention to provide an ultrasound waveguide comprising an electrically conducting section and an electrically isolating section. A reduction of the length of an electrically isolating section possibly decreases the electromagnetic coupling of the high frequency electromagnetic field in the MR environment to the electrically conducting section.

    摘要： An acoustic probe (100) includes an acoustic transducer (20) including a plurality of acoustic transducer elements arranged in a one-dimensional array; and a variably- refracting acoustic lens (10) coupled to the acoustic transducer. The variably-refracting acoustic lens has at least a pair of electrodes (150, 160) adapted to adjust the focus of the variably-refracting acoustic lens in response to a selected voltage applied across the electrodes. In one embodiment, the variably-refracting acoustic lens includes a cavity, first and second fluid media (141, 142) disposed within the cavity, and the pair of electrodes. The speed of sound of an acoustic wave in the first fluid medium is different than the speed of sound of the acoustic wave in the second fluid medium. The first and second fluid media are immiscible with respect to each other, and the first fluid medium has a substantially different electrical conductivity than the second fluid medium.
