METHOD AND SYSTEM FOR 3D ACQUISITION OF ULTRASOUND IMAGES

摘要

The invention relates to a Method for 3D ultrasound image acquisition as well as to a system for conducting the method. The proposed method checks whether the current ultrasound image (401, 402) has at least a pixel in the volume of interest (301), wherein in case the current image (401, 402) has no pixel in the volume of interest (301), the current image (401, 402) is discarded, wherein otherwise the current ultrasound image (401, 402) is segmented and compounded into said 3D model (403) to be generated which is displayed in real-time on the display (101) and particularly overlaid on the displayed pre-acquired image (305), wherein particularly in case a new current ultrasound image (401, 402) is compounded into the 3D model (403), the displayed 3D model (403) on the display (101) is updated. Further, a quality measure for the 3D model (403) to be generated is computed upon acquiring of ultrasound images (401, 402), wherein said acquiring of said ultrasound images (401, 402) is ended once said quality measure has reached a pre-defined level.

1. A Method for 3D ultrasound image acquisition and registration of a 3D model to a pre-acquired 3D image, comprising the steps of:
providing to pre-acquired 3D image (305) of an object (110), displaying said pre-acquired image (305) on a display (101), selecting a volume of interest (301) of the object (110) in said pre-acquired image (305), when the spatial position of the volume of interest (301) is selected or adjusted as intended: triggering the acquisition of ultrasound images (401, 402) in said volume of interest (301) in order to generate a 3D model (403) of said object (110) in said volume of interest (301), and acquiring a plurality of ultrasound images (401, 402) for generating said 3D model (403) by means of said ultrasound probe (103) in the volume of interest (301) while moving the ultrasound probe (103) with respect to said object (110) along the volume of interest (301), and checking if the current ultrasound image (401, 402) has at least a pixel in the volume of interest (301), wherein in case the current image (401, 402) has no pixel in the volume of interest (301), the current image (401, 402) is discarded, wherein otherwise the current ultrasound image (401, 402) is segmented and compounded into said 3D model (403) to be generated, and determining a quality measure for the 3D model (403) to be generated upon said acquisition of said ultrasound images (401, 402), wherein said acquisition of said ultrasound images (401, 402) is ended once said quality measure is fulfilled or has reached a pre-defined level, registering the generated 3D model (403) to the pre-acquired 3D image (305).
