The present invention relates to an ultrasound treatment device for HIFU and an ultrasound image, and to a control method therefor. The ultrasound treatment device comprises: a plurality of image converters disposed on one surface of a probe assembly to transmit ultrasound signals to a target and receive signals reflected by the target to create an ultrasound image; a plurality of high intensity focused ultrasound (HIFU) converters disposed on the surface of the probe assembly so as to be located in different positions from the image converters, wherein the HIFU converters transmit ultrasound signals to a target to generate heat energy, thereby treating a tissue within a focusing area; and a control unit performing control such that the difference between apertures of converter arrays constituted by the image converters and the HIFU converters, respectively, is less than a predetermined value.

Ultrasound treatment device for HIFU and ultrasound image, and control method therefor

The present invention relates to a filter assembly for a medical image signal and a dynamic decimation method using the same. The filter assembly includes a decimation filter that includes an integer number of multiplier accumulators (MACs), changes a cut-off frequency depending on a bandwidth of the medical image signal received through a dynamic impulse response update, and performs a decimation with respect to the received signal according to a decimation ratio, wherein the decimation filter determines a filter coefficient corresponding to an integer interval so as to up-sample the received medical image signal and supplies the filter coefficient to the MACs.
