Abstract
The present invention relates to remotely determining local physical parameters in a fluid-filled cavity (e.g. heart cavities, blood vessels, industrial container) by means of ultrasound waves and encapsulated or stabilised gas bubbles. A measuring method, a method of diagnostic ultrasound of the same and an apparatus for remotely determining ambient physical local parameters of a fluid-filled cavity are disclosed.
