Method for the examination of objects with ultrasound

摘要

For that method to examine an object by using ultrasound waves a spatial region of the object is scanned by a 3D probe. From the reflected echo signals just signals are processed which fulfil certain selectable criteria and taken to display it according to their position on at least one display device. For the representation of one or more objects with one or more interesting layers the geometrical selection criterion is a shell which approximates a surface of the object or of a layer and which can have a certain thickness, and only signals which are selected by this shell will be processed and displayed. This results in a undisturbed representation of the object and allows better view to the characteristic of the surface regarding structure or perfusion.
