Abstract: The process and system generates three-dimensional ultrasound image data sets of diagnostic-quality. A probe which can be inserted into the patient is used to obtain the ultrasound images. The probe is used to generate position information along with the image or image data.

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.

Abstract: A method and apparatus for generating a diagnostically usable three-dimensional image data set is disclosed. The ultrasonic images generated from an ultrasonic apparatus are supplied to an image processing system which uses a position sensor system to determine the spatial location of the ultrasonic image in each dimension. The raw data are transformed into three-dimensional data set having numerous voxels with associated image or gray values, the image or gray values being formed for each voxel according to a preassigned algorithm, to wit from the image or gray values of those image points which are closest in each instance to the current voxel in the unit images or their image planes and whose distance from the current voxel does not exceed a preassigned maximum allowable distance.
