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.

Abstract: The present invention relates to a stress analysis method including: acquiring bio-signals from a test subject; calculating a probability of each of a plurality of stress level values by processing the bio-signals using a deep neural network algorithm; estimating a stress level value with the maximum probability of the plurality of stress level values as a stress level value of the test subject; determining usefulness of the estimated stress level value; and outputting the estimated stress level value determined to be useful through the determination of usefulness, as the final stress level.
