Abstract: A method and an ultrasound medical apparatus for confirming a focal point of a high-intensity focused ultrasound are disclosed. A method of confirming a focal point, for pre-targeting a location of a high-intensity ultrasound by synchronizing the high-intensity ultrasound and an imaging ultrasound and using a reflected signal of the synchronized imaging ultrasound and high-intensity ultrasound from a focal point to which the ultrasounds are transmitted, and an ultrasound medical apparatus for implementing the method are provided.

Abstract: A method and an ultrasound medical apparatus for compensating for a focal point are disclosed. A method and an ultrasound medical apparatus are provided, for transmitting a high-intensity ultrasound having an intensity lower than a predetermined output value to a target object (an affected area of a patient) in a manner that no errors are generated between a focal point on the target object and an actual ultrasound focusing location when transmitting a high-intensity focused ultrasound and compensating a distance of the focal point by using a reflected signal of the ultrasound.

Abstract: Drive mechanisms are provided for a mechanically scanned ultrasound transducer or wobbler. The size, weight, and shape of a wobbler transducer are more optimized by positioning a drive shaft of a motor orthogonal to an array rather than parallel with the array. Different devices may be used for transferring the force of the rotational movement of the motor to the array. A linear bushing transfers rotation motion of an arm connected with a motor to rotational motion of an arm connected with an array in one such device. In another device, a cam transfers rotational motion of the motor to rotational motion of the array.

Abstract: The size, weight, and shape of a wobbler transducer are more optimized by positioning a drive shaft of a motor orthogonal to an array rather than parallel with the array. The drive shaft may be more perpendicular than parallel to the direction of the transducer movement as well. Different devices may be used for transferring the force of the rotational movement of the motor to the array. For example, bevel gears are used to rotate a belt. The array connects with the belt for mechanical movement. As another example, an arm is rotated 180°. The arm slidingly and rotatably connects with the transducer array. As the arm rotates in response to the motor, the array is slid along a rail with bushings. A smaller size motor may be used as large torque may not be needed for driving the array as compared to a typical wobbler transducer. A more ergonomic probe housing, such as a smaller and more desirably shaped housing may be provided.
