  • Patent number: 10321896
    Abstract: Systems and methods for relaying electrical signals representing acoustic response of a volume of tissue to light and ultrasound stimulation. In an embodiment, a plurality of ultrasound transducers receive acoustic energy from the volume and generate electrical energy, which is transmitted via an electrical path to a relay system. The ultrasound transducers are operated at a wide band frequency of at least 1 MHz to 5 MHz to receive acoustic energy from the volume of tissue responsive to light stimulation and at a narrower band frequency to receive acoustic energy from the volume of tissue responsive to acoustic stimulation. The relay system relays the electrical signals to an optoacoustic system or an ultrasound instrument for further processing depending on whether the electrical signals resulted from ultrasound or light stimulation. In an embodiment, optoacoustic, ultrasound, or other images are generated from the electrical signals and may be coregistered, overlayed, or displayed.

The electromagnetically transparent transfer plate can be disposed on the patient bed for imaging an examination region of the examination subject with a first imaging device. For imaging the examination region of the examination subject with the second imaging device that has an electromagnetic localization device, the electromagnetically transparent transfer plate is disposed above the electromagnetic localization device. An imaging system and a corresponding method for medical imaging make use of such a patient position device.

  • Patent number: 9591970
    Abstract: Disclosed is a method of generating a diagnostic image by using a photoacoustic material. The method includes determining a wavelength band of light maximally absorbed by a photoacoustic material, based on at least one or more photoacoustic materials injected into an object, irradiating light, which corresponds to the determined wavelength band, onto an internal region of interest (ROI) of the object to acquire a photoacoustic signal corresponding to the irradiated light, generating a photoacoustic image indicating the ROI by using the photoacoustic signal, and combining and displaying the generated photoacoustic image and an image expressing that the light is being irradiated onto the ROI.

  • Patent number: 9504443
    Abstract: An apparatus for performing measurements in an artery includes a Doppler catheter, comprising a Doppler transducer and a wire connected to the Doppler transducer; and an elongated catheter body having a conduit therein for housing the wire of the Doppler catheter. The body has a proximal end and a distal end; wherein the wire is movable in the conduit relative to the catheter body so that the Doppler transducer and the wire are capable of being threaded into said conduit at the proximal end after the distal end of the catheter has been inserted into the artery, until the Doppler transducer emerges outside the conduit at the distal end of said body for performing ultrasound measurements in the artery. Another embodiment employs at least an additional side transducer for measuring the cross-sectional dimension of the artery useful for computing blood flow.

  • Patent number: 9435730
    Abstract: An image information obtaining apparatus having: a light source; a transducer which detects an acoustic wave and converts the acoustic wave to an electrical signal; a signal processing unit which generates image data, using the electrical signal; and a memory unit which stores a reference acoustic signal produced by the transducer detecting an acoustic wave generated when light is irradiated from the light source onto a phantom having acoustic parameters and optical parameters substantially the same as an object and converting the acoustic wave to an electrical signal, wherein the transducer produces an object acoustic signal by converting the acoustic wave, generated when light is irradiated onto an object from the light source, to an electrical signal; and the signal processing unit subtracts the reference acoustic signal from the object acoustic signal and generates image data from the signal resulting from this subtraction.

  • Patent number: 9345387
    Abstract: Collisions between a minimally invasive surgical instrument and patient tissue are prevented in various ways. In one aspect a body cavity is mapped by recording positions of a surgical instrument, and the map is used to insert another surgical instrument. In another aspect, a surgical instrument is inserted into a space vacated by a guide tube. In yet another aspect, a volume is defined in which a control system permits an instrument to move, and the volume is a sum of one volume that is defined by previous movements of the instrument and other volume that is defined by the boundaries of an image capture component. In yet another aspect, a real time image of a surgical site is mosaiced over a previously recorded more distal image of the site. Surgical instruments are visible in the real time image, and representations of the surgical instruments as they would appear in the previously recorded image are generated and displayed on the previously recorded image.

  • Patent number: 9339255
    Abstract: In an ultrasonic probe including an element part 1 for transmitting and receiving ultrasonic waves, a relay cable 2 connected to the element part 1 and an oscillation mechanism part for oscillating the element part, a cross section of the relay cable 2, which is taken perpendicularly to a rotation axis 3 of the oscillation that is provided to the element part 1 by the oscillation mechanism part, has at least two arc-shaped parts smoothly connected each other, more specifically, S-shape arc-shaped parts or reversed S-shaped parts. In addition, the relay cable 2 is drawn from the surface of the element part 1 facing the rotation axis 3. In this manner, the stress applied to the relay cable 2 during the oscillation of the element part 1 can be dispersed, thereby improving durability of the relay cable 2.
