Abstract:
Disclosed herein is an ultrasound imaging apparatus and a controlling method thereof. The ultrasound imaging apparatus includes a controller configured to generate a control signal to control an operation of a probe, and a transceiver configured to transmit the control signal to the probe and to receive a signal transmitted from the probe. The controller may control the operation of the probe so that the probe may irradiate focused ultrasound energy when contrast agents composed of a silica nanostructure are injected into an object, and the controller may control the operation of the probe so that the probe may irradiate diagnostic ultrasound energy when the focused ultrasound energy is irradiated.
Abstract:
A semiconductor device may include: a semiconductor chip may include a heat radiation part; a pressure chamber formed on the heat radiation part, wherein the pressure chamber is configured to contain coolant such that an internal pressure in the pressure chamber increases as the coolant absorbs heat from the heat radiation part, and the coolant is ejected in a first direction away from the heat radiation part as the internal pressure of the pressure chamber increases; and a cooling channel providing a flow path configured such that the coolant ejected from the pressure chamber flows through the flow path and back into the pressure chamber.
Abstract:
Provided are a method of controlling a temperature of tissue and a temperature controlling apparatus using the method. The method includes measuring a temperature of a target tissue, determining an intensity of ultrasound irradiation with respect to the target tissue based on a target temperature of the target tissue and the measured temperature of the target tissue, and irradiating the ultrasound irradiation having the determined intensity to the target tissue.
Abstract:
An ultrasound irradiation apparatus includes first transducers configured to irradiate first ultrasound energy upon an object with respect to a potential diagnosis and to receive an echo signal which corresponds to the irradiated first ultrasound energy, second transducers configured to irradiate second ultrasound energy upon a region of interest which is determined based on a result of processing of the received echo signal, and a contact pad configured to facilitate a contact between the first transducers and the object, and to facilitate a contact between the second transducers and the object.
Abstract:
A beamforming apparatus configured to beamform ultrasound waves transmitted through an ultrasound transducer having a two-dimensional transducer array includes a transmitter configured to output transmission pulses configured to drive elements constituting the transducer array, and a transmission switch configured to select at least two elements among the elements to form an aperture such that the transmission pulses drive the elements forming the aperture.
