  • Patent number: 9993159
    Abstract: A system and method for using near-infrared or short-wave infrared (SWIR) light sources for early detection and monitoring of breast cancer, as well as other kinds of cancers may detect decreases in lipid content and increases in collagen content, possibly with a shift in the collagen peak wavelengths and changes in spectral features associated with hemoglobin and water content as well. Wavelength ranges between 1000-1400 nm and 1600-1800 nm may permit relatively high penetration depths because they fall within local minima of water absorption, scattering loss decreases with increasing wavelength, and they have characteristic signatures corresponding to overtone and combination bands from chemical bonds of interest, such as hydrocarbons. Broadband light sources and detectors permit spectroscopy in transmission, reflection, and/or diffuse optical tomography. High signal-to-noise ratio may be achieved using a fiber-based super-continuum light source.

  • Patent number: 9820716
    Abstract: A scanner transmits and receives ultrasonic waves at a specified pulse repetition frequency (PRF). A storage stores received signals acquired through the transmission and reception. A calculator generates a Doppler spectrum image by executing frequency analysis on the received signals. A display displays the Doppler spectrum image. When a desired Doppler velocity range for the displayed Doppler spectrum image is inputted, a processor reads out the received signals from the storage, and executes a resampling process on the read-out received signals at a sampling frequency corresponding to the desired Doppler velocity range. The calculator generates a new Doppler spectrum image by executing frequency analysis corresponding to the desired Doppler velocity range on the received signals having been subjected to the resampling process by the processor. The display displays the new Doppler spectrum image.

  • Patent number: 9772389
    Abstract: In a method and magnetic resonance apparatus to acquire diagnostic image data of a contrast agent-filled target area of a patient, a peak time of the test bolus in the target area is automatically determined, from which a wait period is then determined for administering the main bolus. After the main bolus has been administered to the patient, magnetic resonance images of the target area are acquired, and each is analyzed immediately after acquisition thereof to determine whether that image shows arrival of the contrast agent. If and when one of these images shows such arrival, an acquisition protocol is immediately started in order to acquire the diagnostic image data set. If none of these images shows arrival of the contrast agent, the protocol to acquire diagnostic image data is started after the wait period.

  • Patent number: 9662170
    Abstract: The invention relates to a sensing apparatus for sensing an object. The sensing apparatus comprises an ultrasound unit (11) for ultrasonically sensing the object (4), an electrical energy application unit (9) for applying electrical energy to the object (4), and an ultrasound unit shielding element (16) for electrically shielding the ultrasound unit (11), wherein the ultrasound unit shielding element (16) is electrically connected to the electrical energy application unit (9). Since the ultrasound unit shielding element electrically shields the ultrasound unit, the ultrasound sensing of the object is less influenced by a capacitive coupling of the application of electrical energy, in particular, of an RF signal which may be used for applying the electrical energy, into the ultrasound sensing. A further reduction of this influence is achieved by electrically connecting the ultrasound unit shielding element to the electrical energy application unit.

  • Patent number: 9521991
    Abstract: To implement a single-chip ultrasonic imaging solution, on-chip signal processing may be employed in the receive signal path to reduce data bandwidth and a high-speed serial data module may be used to move data for all received channels off-chip as digital data stream. The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. Various novel waveform generation techniques, transducer configuration and biasing methodologies, etc., are likewise disclosed. HIFU methods may additionally or alternatively be employed as a component of the “ultrasound-on-a-chip” solution disclosed herein.
