ULTRASOUND IMAGING SYSTEM AND METHOD FOR IMAGE GUIDANCE PROCEDURE

摘要

The present invention relates to an ultrasound imaging system (10) comprising an ultrasound probe (20) having a transducer array (21) configured to provide an ultrasound receive signal. The system further comprises a B-mode volume processing unit (30) configured to generate a B-mode volume (31) based on the ultrasound receive signal, and a B-mode image processing unit (40) configured to provide a current B-mode image (41) based on the B-mode volume (31). The system further comprises a memory (50) configured to store a previously acquired 3D-vessel map (51). Also, the system comprises a registration unit (60) configured to register the previously acquired 3D-vessel map (51) to the B-mode volume (31) and to select a portion (61) of the 3D-vessel map corresponding to the current B-mode image (41). Further, the system comprises a display configured to display an ultrasound image (71) based on the current B-mode image (41) and the selected portion (61) of the 3D-vessel map (51). The present invention further relates to a method for providing such ultrasound image with vessel information and a corresponding computer program.

主权项

1. An ultrasound imaging system comprising:
an ultrasound probe having a transducer array configured to provide an ultrasound receive signal, a B-mode volume processing unit configured to generate a B-mode volume based on the ultrasound receive signal, a B-mode image processing unit configured to provide a current B-mode image based on the B-mode volume, a vessel segmentation unit configured to create a 3D-vessel map by performing a vessel segmentation technique, a memory configured to store the previously acquired 3D-vessel map, a registration unit configured to register the previously acquired 3D-vessel map to the B-mode volume and to select a portion of the 3D-vessel map corresponding to the current B-mode image, a display configured to display an ultrasound image based on the current B-mode image and the selected portion of the 3D-vessel map, and an image processing unit configured to overlay the current B-mode image and the selected portion of the 3D-vessel map to provide the ultrasound image.
