DIAGNOSTIC ULTRASOUND APPARATUS AND PULSE WAVE MEASUREMENT METHOD

WIPO Patent Application WO/2015/107993

A1

Provided is a diagnostic ultrasound apparatus capable of obtaining more reliable pulse wave information with a relatively small number of measurements. The calculation unit of the diagnostic ultrasound apparatus is provided with a pulse wave measurement unit for measuring pulse waves that move inside a blood vessel in a living body using echo signals that are reflected at two locations of the blood vessel wall when multiple ultrasound beams are irradiated at a slant relative to the blood vessel. The pulse wave measurement unit obtains, for the multiple ultrasound beams, the respective temporal changes of a first echo signal reflected from the side of the blood vessel that is closer to the probe and a second echo signal reflected from the side that is further from the probe and calculates the pulse wave velocity using the difference in time that changes arising from the pulse wave occur at the respective reflection origins (measurement points) and the distance between measurement points in the direction in which the blood vessel runs.
