Abstract: The present invention pertains to: a switching device based on spin-orbit torque; and a method for manufacturing same. A switching device based on spin-orbit torque according to an embodiment comprises: a heavy metal input terminal extending in a first direction; and an information terminal extending in a second direction perpendicular to the first direction on the heavy metal input terminal and having a ferromagnetic layer, wherein the information terminal includes a first region adjacent to the heavy metal input terminal and a second region not adjacent to the heavy metal input terminal, and magnetization reversal of the ferromagnetic layer can be controlled on the basis of a non-uniform spin Hall effect (SHE) caused by the first region and the second region.

Abstract: Disclosed are an ultrasound imaging system for analysis of a body composition and an operation method of an ultrasound imaging system which is designed for analysis of a body composition. An ultrasound imaging system may include: a scan device into which an object is insertable; an ultrasonic probe connected to a part of the scan device; a controller configured to control the ultrasonic probe to emit a transmission ultrasonic signal to the object at multiple positions at the scan device, and receive a reflection ultrasonic signal reflected from the object; and an image processor configured to generate multiple 2D ultrasound images based on reflection ultrasonic signals received at the multiple positions at the scan device, respectively, and generate a 3D ultrasound image based on the multiple 2D ultrasound images.
