摘要： The absolute pressure inside the heart with respect to heartbeat time phase is measured non-invasively or with minimal invasion. An ultrasonic diagnostic device comprising: a pressure sensor that detects artery pressure non-invasively; a reference pressure computation part that converts the artery pressure into absolute reference pressure with respect to a reference point; a spatial pressure difference calculation part that calculates a spatial pressure difference between the reference point and a location distinct from the reference point; and an absolute pressure computation part that calculates intracardiac absolute pressure using a shape image, the reference pressure, and the spatial pressure difference.

摘要： An ultrasound imaging apparatus comprising a plurality of transducer elements images an object by making use of the plurality of transducer elements whose received signals are given delays, transmitting a pulse ultrasonic wave to the object and receiving its reflected wave. The transducer elements are divided into a plurality of blocks and the transducer elements in each of the blocks are selected by a selecting means so that the delays given to the received signals for the transducer elements in each of the blocks are identical.
