  • Publication number: 20210030393
    Abstract: In an ultrasonic CT device for breast examination, unevenness of an ultrasonic image due to a distribution of inclination angles of a breast is reduced. The distribution of the inclination angles of a surface of a subject in a contour of the subject is obtained from a tomographic image, and a signal level of a reception signal or a pixel value of the tomographic image is corrected using the distribution of the inclination angles.

  • Publication number: 20210022705
    Abstract: To provide an ultrasonic CT apparatus that can change an inclination of a side surface of a breast such that an ultrasonic wave is incident on a surface of an entire circumference of the breast at an angle close to perpendicular, and that has less psychological burden on a subject. A container provided with an opening to which the breast is inserted is disposed below a bed provided with a through hole to which the breast of the subject is inserted. In the container, a member that propagates or transmits the ultrasonic wave is disposed, and the member is relatively pressed against a side surface or a nipple portion of the breast such that an inclination of the side surface of the breast is close to perpendicular. A transducer array emits the ultrasonic wave around the breast with the inclination of the side surface being close to perpendicular.

  • Patent number: 10799217
    Abstract: A sinogram is corrected in a form that can use a straight-ray type reconstruction method while considering trajectory of refracted waves. Specifically, based on the sequentially estimated path information of the virtual waves, an arrival time difference sinogram is corrected by a difference or a ratio between “shortest arrival time of wave” and “arrival time of the wave through the shortest path” to each detection element.

  • Publication number: 20200320750
    Abstract: An object of the invention is to provide a user with information that serves as a material for determining whether an image generated by processing including a neural network is valid. A reception signal output by an ultrasonic probe that has received an ultrasonic wave from a subject is received, and an ultrasonic image is generated based on the reception signal. A trained neural network receives the reception signal or the ultrasonic image, and outputs an estimated reception signal or an estimated ultrasonic image. A validity information generation unit generates information indicating validity of the estimated reception signal or the estimated ultrasonic image by using one or more of the reception signal, the ultrasonic image, the estimated reception signal, the estimated ultrasonic image, and output of an intermediate layer of the neural network.

  • Publication number: 20200008784
    Abstract: The invention is to provide an ultrasonic image with a clear tissue structure while reducing speckle noise of the ultrasonic image. An ultrasonic wave is transmitted from the transducer to the subject, and an echo generated in the subject is received. The first ultrasonic image and the second ultrasonic image are generated using a reception signal. The second ultrasonic image is an image smoother than the first ultrasonic image. The image processing unit calculates filter coefficients using pixel values of corresponding pixels of the first ultrasonic image and the second ultrasonic image, and generates an output image by processing one of the first ultrasonic image and the second ultrasonic image using the filter coefficients.
