Abstract
The process and system generates three-dimensional ultrasound image data sets of diagnostic-quality. A distance sensor is attached to and used in conjunction with the ultrasound head to determine position information along with image information as the ultrasound head is moved along the surface of the patient.

Process for generating a diagnostic-quality three-dimensional image data set using an ultrasound device (6) with a freely guidable ultrasound head (7) for producing a sequence of single ultrasound images in various planes of the volume to be examined, using an image processing facility (1) to which the single ultrasound images are transferred and using at least one position sensor (8, 8a, 8b) that defines at least the position of the ultrasound head and therefore the position of the image plane of the respective generated ultrasound image, the data of which are also transferred to the image processing facility (1), which generates a three-dimensional volume date set for tomographic recording of the examined volume from the image data of the single ultrasound images and the position data, characterized in that the position sensor element is a distance sensor (8, 8a, 8b) that is attached to the ultrasound head (7) and that is moved with the ultrasound head (7) along the surface of the volume to be examined bearing on this surface.
