    Abstract: Provided is a geometric model establishment method based on medical image data, including: a step of reading medical image data; a step of defining a tissue type by a conversion relationship between the medical image data and the tissue type; a step of deciding the number of tissue clusters; a step of defining a tissue density by a conversion relationship between the medical image data and the density; a step of establishing 3D encoding matrix with information about the tissue and the density; and a step of generating a geometric model. According to a conversion relationship between medical image data and a tissue type, the number of tissue clusters can be determined according to actual requirements, so that the tissue type, the element composition and the density are provided more accurately, and an established geometric model is better matched to the real situation reflected by the medical image data.

  • Patent number: 10670695
    Abstract: A radar sensing system for a vehicle has multiple transmitters and receivers on a vehicle. The transmitters are configured to transmit radio signals which are reflected off of objects in the environment. There are one or more receivers that receive the reflected radio signals. Each receiver has an antenna, a radio frequency front end, an analog-to-digital converter (ADC), and a digital signal processor. The transmitted signals are based on spreading codes generated by a programmable code generation unit. The receiver also makes use of the spreading codes generated by the programmable code generation unit. The programmable code generation unit is configured to selectively generate particular spreading codes that have desired properties.

  • Patent number: 10649083
    Abstract: An ultrasound imaging system (100) includes at least first and second arrays (108) of transducer elements, which are angularly offset from each other in a same plane. Transmit circuitry (112) excites the first and second arrays to concurrently transmit over a plurality of angles. Receive circuitry (114) controls the first and second arrays to concurrently receive echo signals over the plurality of angles. An echo processor (116) processes the received signals, producing a first data stream for the first array and a second data stream for the second array. The first and second data streams include digitized representations of the received echo signals. A sample matcher (118) compares samples of the first and second data streams and determines a cross-correlation there between. A correlation factor generator (120) that generates a correlation factor signal based on the determined cross-correlation.

  • Patent number: 10641879
    Abstract: The present disclosure relates to an ultrasound multi line dynamic receive focusing beam former that is part of an ultrasound system, where the beam former of the present invention resolves conceptually the, in the prior art dynamic receive focusing beam formers, by fundament, internally generated distortions, which (in the prior art), become internally generated by the beam former process itself. These distortions within prior art beam formers, typically compromises, to some degree, the ability of accurate detections after the dynamic receive focusing beamforming. The present invention advantage is an ultrasound system capable of very accurate focusing selectivity with a high dynamic range, and very low signal distortion, therefore capable of, for example, a clear detection of harmonics and super harmonics, due to the fundamentally absence of internal distortion-generation.

  • Patent number: 10613058
    Abstract: In some examples, a capacitive micromachined ultrasonic transducer (CMUT) array may include a plurality of CMUT elements arranged in a plurality of rows, each row including multiple CMUT elements. A bias voltage supply may be connected for supplying bias voltages to a first row, a second row, and a third row of the plurality of rows. In addition, a processor may be configured by executable instructions to control the bias voltages by applying a first bias voltage to the second row, and a second, different bias voltage to the first and third rows to configure the CMUT elements of the second row to at least one of transmit or receive ultrasonic energy with different efficiency than the CMUT elements of the first row and the third row. In some examples, individual contributions from different rows can be computed from different firing sequences for synthetic aperture beamformation in an elevation dimension.

  • Patent number: 10561400
    Abstract: To provide an ultrasonic diagnostic apparatus and an ultrasonic diagnostic method capable of conducting ultrasonic diagnosis using acoustic radiation pressure, without causing an increase in the temperature of an ultrasound-exposed portion. A push pulse transmitter outputs a coded pressurization pulse signal. A track pulse transmitter outputs a measurement pulse signal for measurement. An ultrasound probe outputs an ultrasonic wave for generating a shear wave in a target object on the basis of the pressurization pulse signal, and an ultrasonic wave for measurement on the basis of the measurement pulse signal. An echo receiver receives an echo of the ultrasonic wave for measurement, and outputs an electric signal. An elastic modulus estimator decodes the electric signal output by the echo receiver, and estimates an elastic modulus of the target object on the basis of the decoded signal.
