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.

Claims

1. Process for generating a diagnostic-quality three-dimensional image data set using an ultrasound device with an ultrasound configuration (9) for producing a sequence of 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 means of producing position information defining the position of the ultrasound configuration (9) that is also transferred to the image processing facility (1), which generates a three-dimensional volume data set for tomographic recording of the examined volume from the image data of the single ultrasound images and the position information, characterized in that the at least one ultrasound configuration (9) is part of a probe (7), preferably part of a TEE probe.

2. Process according to

claim 1

, characterized in that the at least one ultrasound configuration (9) is part of a probe (7) that can be inserted into the volume to be examined.

3. Process according to

claim 1

or

2

, characterized in that the ultrasound device generates single images from the image data provided by the probe (7) containing the position information in the respective image or in the respective image data, and that this information is extracted in the image processing facility and is stored together with the image data, preferably in an image header of the image data.

4. Process according to one of the foregoing claims, characterized in that the position information is taken over by the data processing facility (1) from an image header of the single images created by the ultrasound device (6).

5. Process according to one of the foregoing claims, characterized in that in case the image processing facility (1) is integrated into the ultrasound device (6) the position information determined by a computer from the data of the probe (7) is taken over directly for generating the three-dimensional image data set.

9. System according to one of the foregoing claims, characterized in that the position information is taken over by the data processing facility (1) from an image header of the single images created by the ultrasound device (6).

10. System according to one of the foregoing claims, characterized in that in case the image processing facility (1) is integrated in the ultrasound device (6), the position information determined by a computer from the data of the probe (7) is taken over directly for generating the three-dimensional image data set.

6. System for generating a diagnostic-quality three-dimensional image data set using an ultrasound device with an ultrasound configuration (9) for producing a sequence of 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 means of producing position information defining the position of the ultrasound configuration (9) that is also transferred to the image processing facility (1), which generates a three-dimensional volume data of the for tomographic recording of the examined volume from the image data of the single ultrasound images and the position information, characterized in that the at least one ultrasound configuration (9) is part of a probe (7) that can be inserted into the volume to be examined, preferably part of a TEE probe.

7. System according to

claim 6

, characterized in that the at least one ultrasound configuration (9) is put of a probe (7) that can be inserted into the volume to be examined.

8. System according to

claim 6

or

7

, characterized in that the ultrasound device generates single images from the image data provided by the probe (7), which contains the position information in the respective image or in the respective image data, and that this information is extracted in the image processing facility (1) and stored together with the image data preferably in an image header of the image data.
