A beamforming device includes a sampler configured to sample a signal reflected from a focal point and received to a transducer array; a mixer configured to separate the sampled signal into an in-phase component signal and a quadrature component signal; a low pass filter configured to perform filtering on the in-phase component signal and the quadrature component signal; a decimator configured to perform decimation on the filtered in-phase component signal and quadrature component signal; a sampling delay compensator configured to compensate a sampling time delay based on a preset time delay resolution for the decimated in-phase component signal and quadrature component signal; a phase rotator configured to compensate a phase delay based on a preset phase resolution for the in-phase component signal and the quadrature component signal for which the sampling time delay is compensated; and a delay calculator configured to calculate a time delay resolution and the phase resolution, and to apply each to the sampling delay compensator and the phase rotator.

Beamforming device, method of controlling the same, and ultrasound diagnostic apparatus

The present invention relates to an ultrasound treatment device for HIFU and an ultrasound image, and to a control method therefor. The ultrasound treatment device comprises: a plurality of image converters disposed on one surface of a probe assembly to transmit ultrasound signals to a target and receive signals reflected by the target to create an ultrasound image; a plurality of high intensity focused ultrasound (HIFU) converters disposed on the surface of the probe assembly so as to be located in different positions from the image converters, wherein the HIFU converters transmit ultrasound signals to a target to generate heat energy, thereby treating a tissue within a focusing area; and a control unit performing control such that the difference between apertures of converter arrays constituted by the image converters and the HIFU converters, respectively, is less than a predetermined value.

Ultrasound treatment device for HIFU and ultrasound image, and control method therefor

Provided is an ultrasonic imaging apparatus including: an inputter configured to receive an input of a region of interest (ROI) from a user; a beamformer configured to perform transmission/reception focusing with respect to a virtual source to be used for a synthetic aperture focusing method; a display; and a main controller configured to determine a position of the virtual source on the basis of an image quality in the received ROI and control the display to display the determined position of the virtual source.

Ultrasonic imaging apparatus and method of controlling the same

The present disclosure relates to an ultrasound therapy device using high-intensity focused ultrasound (HIFU) and a control method thereof. The ultrasound therapy device comprises: an array type HIFU converter having a plurality of HIFU conversion elements; and a control unit for performing a control to treat tissues in a focusing area by selecting and driving some of the HIFU conversion elements of the array type HIFU converter and irradiating ultrasound signals to an object through the driven active conversion elements to generate heat energy, wherein, after an elapse of a predetermined time period, the control unit drives a combination of other conversion elements as new active conversion elements in replacement of the active conversion elements.

Ultrasonic therapy device using HIFU and control method thereof

Provided is an ultrasound diagnosis apparatus including a probe configured to transmit a plurality of plane waves at a plurality of steering angles and a controller configured to determine the plurality of plane waves so that a grating lobe of a synthetic transmit focusing beam pattern using the plurality of plane waves is located outside a region of interest.

Ultrasonic diagnostic apparatus and method for controlling ultrasonic probe to transmit a plurality of plane wave sets at a plurality of steering angles so that a grating lobe is outside a region of interest
