  • Patent number: 10159469
    Abstract: An embodiment in accordance with the present invention provides a device and method for a transrectal ultrasound (TRUS) guided prostate biopsy. The device includes an ultrasound wand equipped with a lateral fire ultrasound sensor. The ultrasound wand also defines a channel having an oblique path though the wand. The channel accommodates a biopsy needle, which can be pivoted as well inserted through the channel to different depths in order to perform a biopsy of the prostate. The device therefore uses only three degrees-of-freedom of movement in order to obtain the biopsy samples. Additionally, the ultrasound wand can be used to generate a three-dimensional image of the prostate.

  • Patent number: 10147314
    Abstract: Example apparatus and methods provide improved spatial and temporal resolution over conventional magnetic resonance renography (MRR). Example apparatus and methods reconstruct under-sampled three-dimensional (3D) data associated with nuclear magnetic resonance (NMR) signals acquired from a kidney. The data is reconstructed using a 3D through-time non-Cartesian generalized auto-calibrating partially parallel acquisitions (GRAPPA) approach. Example apparatus and methods produce a quantized value for a contrast agent concentration in the kidney from a signal intensity in the data based, at least in part, on a two compartment model of the kidney. The two compartment model includes a plasma compartment and a tubular compartment. The quantized value describes a perfusion parameter for the kidney or a filtration parameter for the kidney.

  • Patent number: 10130338
    Abstract: A side-fire ultrasonic probe includes an alignment feature that, when used to connect the probe with a needle guide for intra-cavity medical procedures, enables alignment of a needle in an imaging plane of an ultrasonic transducer. The alignment feature is configured such that alignment of the needle within the imaging plane is accomplished when a protective sheath is disposed between the alignment feature and the needle guide. This configuration can be used with high frequency ultrasonic arrays having frequency distributions centered at about 20 MHz, and for medical procedures, such as biopsying organs or other bodily intra-cavity structures, and delivering intra-cavity therapies.

  • Patent number: 10123770
    Abstract: A system for supporting a patient while scanning a volume of tissue protruding from a patient includes a base having a planar portion configured to support the patient in a prone configuration. A frustoconical portion extends from the planar portion and defines a base aperture configured to receive the volume of tissue. A support assembly couples to the base. A membrane is retained in tension within a frame at a peripheral portion of the membrane. The membrane defines a membrane aperture configured to align with the base aperture, and the membrane is configured to deflect into the frustoconical portion of the base in response to the patient's weight. The system can further include an electrical subsystem including a pressure sensor array configured to generate signals in response to a pressure distribution resulting from the patient's weight at the patient interface system.

  • Patent number: 10105067
    Abstract: The devices and methods generally relate to vibratable sensors for measuring ambient fluid pressure, in particular implantable sensors. The devices and methods are particularly well-suited to implantation within the body of a living animal or human to monitor physiological conditions, such as portal and/or hepatic venous blood pressure, and allow frequent, remote interrogation of venous pressure using the resonance frequency of an implanted sensor. The sensor devices are relatively small compared to conventional devices for measuring fluid pressure and can be implanted in the porto-hepatic venous system, whereas conventional devices are too large. The small size of the device is accomplished by using a thick sensor membrane, compared to conventional devices, and by limiting the size of additional elements of the device relative to the size of the sensor membrane. The thicker sensor member also obviates the need for multiple sensor arrays and maintains the accuracy and robustness of the sensor device.

  • Patent number: 10098614
    Abstract: An ultrasound imaging system includes an ultrasound transducer that receives an echo signal generated in response to an ultrasound signal transmitted by the system interacting with a moving material. Receive circuitry processes the echo signal and produces an electrical signal indicative thereof. Front end electronics amplify and digitize the electrical signal producing M-bit RF data. A beamformer that processes the M-bit RF data and generates N-bit high dynamic range beamformed data. N is greater than M. The system further includes pre-processing circuitry that converts the N-bit data RF to 2×K-bit I/Q data. K is less than M. A velocity processor determines a phase estimate of the moving material from the I/Q data. A rendering engine visually presents the phase estimate.

  • Patent number: 10096126
    Abstract: Methods for registering a three-dimensional model of a body volume to a real-time indication of a sensor position that involve analyzing scanned and sensed voxels and using parameters or thresholds to identify said voxels as being either tissue or intraluminal fluid. Those voxels identified as fluid are then used to construct a real-time sensed three-dimensional model of the lumen which is then compared to a similarly constructed, but previously scanned model to establish and update registration.
