Abstract
A diagnostic ultrasound apparatus is provided for obtaining an image of an object into which an ultrasound contrast agent is injected. The apparatus has a transducer 1 for transmitting and receiving an ultrasound wave to and from the object and transmitting means (2, 81, 83) transmitting an ultrasound pulse into the object by driving the transducer under a first transmitting condition exerting a given destruction capability on the ultrasound contrast agent and a second transmitting condition having a destruction capability lower than that of the first condition. First image producing (3, 5) receive an ultrasound echo of the ultrasound pulse transmitted under the first transmitting condition and produce a first color-displayed image based on phase displacement information about the ultrasound echo. Additionally, second image producing means (3, 4) receive an ultrasound echo of the transmitted ultrasound pulse and produce a second image based on amplitude information about the ultrasound echo. The first and second images are displayed by display means (6, 82). According to this diagnostic ultrasound apparatus, for imaging a CFM image based on a flash echo phenomenon caused in an obje…
