摘要:
A photoacoustic image of an object varies in contrast between a shallow portion and a deep portion according to the irradiation position of the object with respect to an ultrasonic probe. The present disclosure provides an information acquisition apparatus in which the contrast is high regardless of the depth of the region of interest. The information acquisition apparatus includes a varying unit that varies the irradiation position of the object with respect to the ultrasonic probe and controls the irradiation position according to an instruction on a condition for acquiring information on the object.

The ultrasound diagnostic apparatus includes an ultrasound transceiver that, by using a probe, transmits an ultrasound signal to an object, and receives an echo signal corresponding to the ultrasound signal from the object and an operation mode controller that sets an operation mode of the ultrasound transceiver to one of first and second operation modes, based on operation state information of the probe.

A method of displaying an ultrasound image includes reading, based on a user's input, the ultrasound image stored in a storage medium; displaying, on a screen, the ultrasound image and TGC information that is matched to the ultrasound image; receiving an input of modifying the TGC information by adjusting a TGC value in the TGC information, the at least one TGC value corresponding to a depth value; and updating the ultrasound image based on the modified TGC information.

Provided is an ultrasound imaging apparatus. The ultrasound imaging apparatus includes a data acquiring unit transmitting an ultrasound signal to a region of interest (ROI) of an object and then receiving an ultrasound echo signal reflected from the ROI of the object, and a control unit calculating a shear modulus of at least one point in the ROI and a strain of the at least one point, based on the received ultrasound echo signal, and calculating a stress applied to the at least one point by using the shear modulus and the strain.

Disclosed are a method and an apparatus, which enhance a quality of an ultrasound image to provide an improved image. An adaptive demodulation method includes acquiring input radio frequency (RF) data, quadrature-demodulating the input RF data to output an inphase-quadrature (IQ) signal, determining a valid region for the input RF data, and estimating attenuation of a frequency of the IQ signal, based on data included in the valid region among the input RF data and performing frequency compensation corresponding to the estimated attenuation of the frequency.
