## Abstract

An ultrasound system, which operates at a plurality of diagnostic modes, includes: an ultrasound probe configured to transmit an ultrasound signal to a target object and receive an ultrasound echo signal reflected from the target object; a power supplying unit configured to supply a power of different voltage levels according to a diagnostic mode to form a transmit pulse signal to be supplied to the ultrasound probe; and a transmitting unit connected to the ultrasound probe and the power supplying unit, the transmitting unit being configured to constantly supply the power in a first voltage level at a transmission time period of an ultrasound signal and vary the voltage level of the power from the first voltage level to a second voltage level based on a predetermined waveform at a transmission idle time period.

## Claims

### Claim 1

An ultrasound system operating at a plurality of diagnostic modes, comprising:
an ultrasound probe configured to transmit an ultrasound signal to a target object during a transmission period and receive an ultrasound echo signal reflected from the target object during a transmission idle period;
a power supplying unit comprising a plurality of power supplies configured to supply a power of different voltage levels according to a diagnostic mode to form a transmit pulse signal to be supplied to the ultrasound probe;
a switching section configured to connect one of the plurality of power supplies; and
a power control section, at the transmission period, configured to uniformly supply a first power of a first voltage level supplied from a first power supply of the plurality of power supplies connected to the switching section, and at the transmission idle period after the switching section is connected to a second power supply which supplies a second power of a second voltage level, configured to increase or decrease the voltage level of the power supplied by the power control section from the first voltage level to the second voltage level based on a predetermined cosine waveform.
