An ultrasonic diagnostic apparatus includes: a plurality of receiving elements that receive an ultrasonic wave, convert the ultrasonic wave into an electric signal, and output a receiving signal; a first detecting amplifier that detects noise and outputs a noise signal; a second detecting amplifier that amplifies the noise signal and outputs an amplified noise signal; a subtraction amplifier that receives the receiving signal and the amplified noise signal and subtracts the amplified noise signal from the receiving signal; and a plurality of circuit substrates that each include the second detecting amplifier and subtraction amplifier.

Ultrasonic diagnostic apparatus

A control apparatus includes a processor that executes a first point cloud generation process including a first imaging process of acquiring a first image according to a first depth measuring method and a first analysis process of generating a first point cloud and a second point cloud generation process including a second imaging process of acquiring a second image according to a second depth measuring method and a second analysis process of generating a second point cloud, and detects the object using the first point cloud or the second point cloud. The first point cloud generation process completes in a shorter time than the second point cloud generation process, and the processor starts the second point cloud generation process after the first imaging process and discontinues the second point cloud generation process if the first point cloud satisfies a predetermined condition of success.

Control apparatus, robot system, and method of detecting object

Provided are an ultrasonic measurement apparatus, an ultrasonic imaging apparatus and an ultrasonic measurement method that achieve an increase in processing speed together with an increase in resolution and are user friendly. An image is generated by adding together, with a weight having a fixed value, reception signals obtained by ultrasonic echoes being received by an ultrasonic element array, and an area of interest is set within the area in which the generated image is to be displayed. When an area of interest is acquired, the reception signals received by the ultrasonic element array are added together with weights that depend on the reception signals, with respect to data forming the basis of the image to be displayed in the area of interest, and image generation is performed.

Ultrasonic measurement apparatus, ultrasonic imaging apparatus, and ultrasonic measurement method

An ultrasonic measurement apparatus includes a reception processing unit, a harmonic processing unit, a signal processing unit and an image generation unit. The reception processing unit is configured to receive, as a received signal, an ultrasonic echo corresponding to an ultrasonic wave transmitted toward a subject. The harmonic processing unit is configured to extract a harmonic component of the ultrasonic echo from the received signal. The signal processing unit is configured to add a weighting to the harmonic component by using a weight that varies depending on a value of the harmonic component. The image generation unit is configured to generate an image based on a signal to which the weighting has been added.
