PROBE SYSTEM FOR DOPPLER ULTRASONIC DIAGNOSIS

摘要

A probe system for Doppler ultrasonic diagnosis is provided to calculate blood flow velocity in a blood vessel by using Doppler shifts of ultrasound waves reflected from ultrasound transducers due to a Doppler effect and an angle between the ultrasound transducers. A probe system for Doppler ultrasonic diagnosis includes a first ultrasound transducer(10), a transducer holder(13), and a second ultrasound transducer(11). The first ultrasound transducer inputs ultrasound waves to a blood vessel and measures the ultrasound waves reflected from the blood vessel after a predetermined time. The first ultrasound transducer is obliquely installed in the transducer holder at a predetermined angle to input the ultrasound waves to the blood vessel. The second ultrasound transducer is installed in the transducer holder at a predetermined angle with respect to the first ultrasound transducer.
