  • Patent number: 11457889
    Abstract: A system and a method of non-invasive continuous echocardiographic monitoring is provided with an ultrasound transducer and a bedside monitor. The beside monitor includes a monitor central processing unit (CPU). First, the ultrasound transducer is attached onto a specific skin portion of a patient. The specific skin portion is positioned adjacent to a patient's heart. Next, continuous echocardiographic data is sensed with the ultrasound transducer. After relaying the continuous echocardiographic data from the ultrasound transducer to the monitor CPU, the monitor CPU generates a real-time ultrasound image of the heart from the continuous echocardiographic data. Finally, the real-time ultrasound image is outputted with the bedside monitor. If the bedside monitor has a main screen, then the real-time ultrasound image is displayed through a picture-in-picture format with the main screen.

  • Patent number: 11413005
    Abstract: The disclosed devices, systems and methods measure non-invasive blood pressure in a patient. Energy emissions, such as ultrasound or light, are emitted into tissues of the patient. The emitted energy reflects from various tissues, such as flowing blood and vessels, and can be detected, or received, to generate a reflected energy signal or data. The reflected energy can be processed, such as by using a constitutive equation, to calculate the blood pressure.

  • Patent number: 11156686
    Abstract: An apparatus includes a high intensity focused ultrasound (HIFU) system and a magnetic resonance (MR) imaging system. A memory stores: instructions, pulse sequence commands for an acoustic radiation force imaging protocol, and first and second sonication commands. The pulse sequence commands specify acquisition of the MR data for first and second pulse sequence repetitions. The pulse sequence commands specify for each of the sequence repetitions a first and a second group of motion encoding gradients. Execution of the instructions causes a processor to: acquire first and second MR data by controlling the MR imaging system with the pulse sequence commands and by controlling the HIFU system with the first and second sonication commands, respectively; reconstruct first and second motion encoded images from the first and second MR data, respectively; and construct a displacement map from the difference of the first and second motion encoded images.

  • Patent number: 11122992
    Abstract: A method, including receiving from a sensor affixed to a probe, signals output by the sensor in response to a calibrated magnetic field, and estimating, using calibration data, location coordinates of the sensor. Using the calibration data and the estimated location, an estimated vector including orientation coordinates is computed, and updated orientation coordinates that best fit the received signals to the estimated vector are computed for the estimated location. Based on the updated orientation, updated location coordinates that best fit the received signals to the estimated vector are computed. The steps of computing the vector, computing the orientation, and computing the location and monitoring changes in the updated location are repeated until the changes are linear. Upon the changes being linear, a final location of the sensor is computed using a linear projection from the updated location, and a position of the probe is presented based on the final location.

  • Patent number: 11116479
    Abstract: An ultrasonic diagnostic imaging system and method acquire a sequence of image data as a bolus of contrast agent washes into and out of the liver. The image data of contrast intensity is used to compute time-intensity curves of contrast flow for points in an ultrasound image. Time-dependent data is calculated from the data of the time-intensity curves which, in a described implementation, comprise first and second derivatives of the time-intensity curves. A color map is formed of the time-dependent data or the polarities of the data and displayed in a parametric image as a color overlay of a contrast image of the liver.
