Abstract

In a medical treatment/examination device and method for the acquisition and presentation of a medical instrument introduced into a cavity organ of a patient to be examined or treated, particularly in the framework of a cardial examination or treatment with a catheter, intracorporeal registration of 2D ultrasound images of the cavity organ is undertaken using a catheter-like ultrasound acquisition device guided into the cavity organ with simultaneous acquisition of the spatial position and orientation of a 2D ultrasound image by a position acquisition system, a 3D ultrasound image dataset is generated from the 2D ultrasound image, following introduction of the instrument, the instrument is acquired in a coordinate system registered with the 3D ultrasound image dataset, and a 3D reconstruction image is generated on the basis of the 3D image dataset and is presented at a monitor, containing a positionally exact presentation of the instrument in the 3D reconstruction image.
