Device and process for quantifying bodies by means of ultrasound
First Claim
1. Device for quantification of bodies that are contained in an object under examination, comprising a) at least one transducer for emitting an ultrasound field with which the bodies that are contained in a layer in the object under examination can be excited to emit characteristic ultrasonic signals, and to receive characteristic signals, b) at least one data processing system to determine the number of bodies in the layer that consists of the characteristic signals, as well as c) means with which the ultrasound field can be shifted after an excitation of bodies in a first layer in an object under examination, such that bodies can be excited after shifting into a second layer, whereby the first layer and the second layer overlap and are displaced relative to one another in a parallel and defined manner.

Abstract
In the quantification of bodies, especially bubbles, in ultrasonic diagnosis, the problem exists that the concentration of bodies, especially bubbles, is often so high that the image data that is obtained relative to the visualization becomes saturated, such that a quantification is impossible. To solve this problem, it is proposed that the bodies that are contained in the sectional layers of an object under examination first be excited by means of ultrasound to produce characteristic signals and to pick up these signals, to form data sets from the signals, to convert the data sets into an image of the body arrangement in the object under examination and to determine the number of bodies therefrom, whereby at least two ultrasonic signal sets from overlapping sectional layers in the object under examination are picked up.

15. Process for quantification of bodies that are contained in an object under examination, in which
a) bodies with an ultrasound field that are contained in a layer in the object under examination are excited to produce characteristic ultrasonic signals, b) the ultrasonic signals are received, c) the number of bodies is determined from the ultrasonic signals that are received, and d) after bodies are excited in a first layer in the object under examination, the ultrasound field is shifted such that bubbles are excited after displacement into a second layer, whereby the first layer and the second layer overlap and are shifted relative to one another in a parallel and defined manner.
