Medical imaging system and a method for segmenting an object of interest

摘要

The invention concerns a medical imaging system comprising means (4) of segmenting a region of interest around an object of interest within a volume of 3D data (3DV). The system according to the invention comprises means (5) of calculating a sub-regions map (CSR) within the segmented region (RS) and correction means (6) intended to exclude sub-regions of the segmented region by means of said sub-regions map (CSR). The correction can be made automatically or manually by means of control means (7) enabling a user to select the sub-regions to be excluded. Display means (3) make it possible to display a 2D representation (2DR) of the volume of 3D data (3DV) and the segmented region (RS, RS′) at various stages of the processing.

主权项

1. A medical imaging system comprising:
a memory that is configured to store data corresponding to a three-dimensional region of interest that includes at least one object of interest, a calculation unit that is configured to:
identify a segment of interest corresponding to a contour of the object of interest, by identifying points in the segment of interest having similar characteristics based on the data,identify a plurality of sub-segments within the segment of interest, boundaries of the sub-segments being based on variations of at least one characteristic within the segment of interest, andremove select sub-segments from the segment of interest to form an other segment of interest corresponding to the contour of the object of interest, and a display unit that is configured to display the segment of interest, the boundaries of the sub-segments, and the other segment of interest.
