A determination device that determines quality of target portion based on sensor data obtained by a sensor measuring the target object, includes one or more processors configured to acquire sensor data representing the target portion, acquire information indicating a changed portion, determine whether the target portion includes the changed portion based on acquired information, determine a first label of the target portion represented in the sensor data by using a determination model learned from a training dataset based on training target portions, the first label representing target portion as one of good, defect, and a defect candidate, accept a second label of the target portion input via a user interface when the target portion includes the changed portion or when the first label of the target portion is determined as the defect candidate, and perform quality determination of the target portion based on the first label and/or the second label.

Determination device and determining method thereof

A biological clock time calculating apparatus includes: a measuring portion which measures bio-information that changes on a daily basis; and an arithmetic processing portion which calculates biological clock time based on a measurement result of the measuring portion. A biological clock time calculating method may be configured to include: measuring bio-information which changes on a daily basis; and calculating biological clock time based on the measurement result.

Biological clock time calculating apparatus and biological clock time calculating method

An image generation apparatus including a computation processing section that generates an ultrasonic image from a received signal associated with each scanning of an object in which an ultrasonic wave is transmitted and received is provided. The computation processing section sets, for each scanning, a selection range over which the received signal is received and which includes the direction of the scanning, calculates weights used in a beamforming process based on the received signals within the selection range, and carries out the beamforming process based on the weights to generate an image associated with the scanning.

Image generation apparatus and image generation method

An ultrasonic measurement apparatus includes a transmission processing unit that performs processing for transmitting an ultrasonic wave at a given transmission angle, a reception processing unit that performs reception processing of an ultrasonic echo with respect to a transmitted ultrasonic wave, and a processing unit that performs processing with respect to a reception signal from the reception processing unit. The processing unit obtains a plurality of first resolution signals by synthesizing a plurality of the reception signals based on a first beamforming coefficient, and obtains a second beamforming coefficient for synthesizing a second resolution signal from the plurality of first resolution signals based on whether a signal processing target point belongs to a plane wave propagation region or belongs to a spherical wave propagation region.

Ultrasonic measurement apparatus, ultrasonic diagnostic apparatus, and ultrasonic measurement method

A signal synthesizing unit performs aperture synthesis of output signals from conversion element groups which are arranged in a matrix and convert ultrasonic waves into electric signals, and sequentially outputs a first image signal, for every transmission of the ultrasonic waves. A signal addition unit adds the first image signals output from the signal synthesizing unit together for each group so as to output a second image signal. An adaptive signal processing unit calculates an adaptive weight on the basis of the second image signal, and synthesizes the second image signals with each other.

Ultrasonic image apparatus, control device for ultrasonic image apparatus, and ultrasonic image forming method

An ultrasonic measurement apparatus includes a transmission processing unit that performs processing for transmitting an ultrasonic wave at a given transmission angle, a reception processing unit that performs reception processing of an ultrasonic echo with respect to the transmitted ultrasonic wave in first to Nth (N is an integer equal to or greater than 2) ultrasonic transducers; and a processing unit that performs processing with respect to first to Nth reception signals corresponding to the first to Nth ultrasonic transducers. The processing unit performs first phasing processing when a signal processing target point exists in a plane wave propagation region, and performs second phasing processing when the signal processing target point exists in a spherical wave propagation region, as phasing processing with respect to each of the reception signals of the first to Nth reception signals.
