    Abstract: A focused ultrasound stimulation apparatus according to the present disclosure includes a transducer which outputs low intensity/high intensity ultrasound, an acoustic lens which is placed in close contact with a user's skin and is customized to focus the ultrasound onto a target focal point, and a fixture for fixing the transducer and the acoustic lens to each other. The acoustic lens is customized using a 3-dimensional (3D) printer based on the pre-captured user's cranial shape, to focus the ultrasound a desired focus target for each user, thereby improving accuracy compared to conventional ultrasound stimulation apparatus.

    Abstract: An image registration system using a subject-specific tracker includes: a photographing unit for obtaining a scanning image; a fabricated tracker based on anatomical data of the user including tracking markers for defining relative positions; a recognizing unit configured to recognize positions of the tracking markers and an image registration unit configured to register the scanning image based on the positions of the tracking markers. According to the system, a body part of the user and a scanning image may be automatically registered without a conventional image registration process such as an attachment of a fiducial marker and a confirmation of the fiducial marker position using CT/MRI imaging. Accordingly, it is possible to minimize an error caused by human, ensure precise registration, allow trackers to be attached or detached as necessary during surgery operation, and keep the accuracy of registration after the trackers are attached or detached.
