Abstract
An ultrasound diagnosis apparatus in comprising a transformer, a first power source and a second power source, an ultrasound transducer, a processor, and a driving part. The transformer comprises a primary winding and a secondary winding. The first power source and the second power source are connected to the primary winding. The ultrasound transducer is driven by the voltage induced to the secondary winding, and transmits ultrasound waves to a subject, and receives reflected waves reflected by the subject to output the received signal. The processor implements processing on the received signal to generate ultrasound wave images. The driving part drives to change the voltage among a first level voltage based on the first power source, a second level voltage based on the second power source, and a third level voltage between the first level voltage and the second level voltage.
