Abstract: The tissue removal device using focused ultrasound includes a focused ultrasound output unit, a mode setting unit to set an output mode of the focused ultrasound, and a control unit to control output characteristics of the focused ultrasound according to the set mode, wherein the output mode is selected from a first mode for removing a tissue in a local area using a vapor bubble formed by the focused ultrasound, a second mode for removing a tissue in a narrower area than the first mode by controlling the output characteristics of the focused ultrasound immediately after the vapor bubble is formed by the focused ultrasound, and a third mode for obtaining a skin tightening effect by generating heating in a subcutaneous fat layer using focused ultrasound of lower intensity and a longer pulse length than the first mode and the second mode.

Abstract: According to an embodiment of the present disclosure, there is provided a completely new type of 3-dimensional (3D) printing method for producing an object by focusing ultrasound onto material that changes in state by stimulation to solidify it into a desired shape. The method for 3D printing according to an embodiment includes providing material which changes in state by stimulation, setting a target focal point in the material, focusing ultrasound onto the target focal point using at least one ultrasound transducer, and applying stimulation to the material using the focused ultrasound to induce a change in state of the material. According to the embodiments, it is possible to control the precision of the output by controlling the frequency of the ultrasound transducer or the size of the target focal point on system.

Abstract: An apparatus for tissue ablation according to an embodiment of the present disclosure includes an ultrasound output unit to output focused ultrasound, and a control unit to control an intensity of the focused ultrasound, wherein the control unit may be configured to control the intensity of the focused ultrasound below a setting value, when a first condition in which a vapor bubble is formed in a tissue or a second condition in which a temperature of the tissue reaches a threshold is accomplished during the output of the focused ultrasound to the tissue. According to this embodiment, it is possible to precisely control vapor bubble dynamics without generating the shockwave scattering effect by instantaneously controlling the acoustic pressure and the intensity of the focused ultrasound, and prevent damage to a tissue other than a lesion to be removed.

Abstract: Disclosed herein is a non-invasive treatment system using intermedium, and an exemplary treatment system is configured to output high-intensity focused ultrasound to remove bone tissue, inject an acoustically-transparent medium into a part where the bone tissue is removed to generate an intermedium, and output therapeutic ultrasound that passes through the intermedium. Accordingly, the bone tissue is removed in a non-invasive way using high-intensity focused ultrasound, and the intermedium is generated at the bone tissue removed site, to increase the penetration of therapeutic ultrasound or generate ultrasound itself, thereby improving an ultrasound treatment effect while minimizing the side effect (for example, infection of dura mater) of invasive surgery methods.

Abstract: A high-low intensity focused ultrasound treatment apparatus according to the present disclosure includes a plurality of ultrasound sources, and a controller to control a center frequency and intensity of focused ultrasound outputted from the ultrasound sources, wherein each of the ultrasound sources includes a first ultrasound transducer to output low-intensity focused ultrasound to detect a lesion, and a second ultrasound transducer to output high-intensity focused ultrasound to ablate or remove the detected lesion. The low-intensity focused ultrasound outputted from the first transducer may be used to detect a lesion in a patient's brain by applying a stimulus to the brain, and at the same time, investigating a response, and the high-intensity focused ultrasound outputted from the second transducer may be used to ablate or remove the detected lesion by applying a thermal or mechanical stimulus to the lesion.
