Method and system for indicating a feeding vessel of a malformation in a medical image

摘要

A method and a system for indicating a feeding vessel of a malformation in a medical image are provided. The method first displays the medical image of the malformation and its surrounding vessels. This enables a manual selects a portion of the displayed medical image with reference to the tumor. The feeding vessel of the tumor is segmented and finally indicated in the medical image based on said manual selection.

1. A method for indicating a feeding vessel of a malformation in a medical image, comprising:
displaying the medical image of the malformation and surrounding vessels by a display device; manually selecting a portion of the displayed medical image in reference to the malformation by a selector; segmenting the feeding vessel of the malformation by a processor; indicating the segmented feeding vessel in the medical image by the display device, manually selecting a point in the segmented feeding vessel indicated in the medical image by the selector as an initial catheter position for a simulation of embolization; identifying a blood flow direction in the segmented feeding vessel by the processor; indicating a part of the segmented feeding vessel in the blood flow direction after the selected point in the medical image by the display device; and iteratively manually selecting a new point in the segmented feeding vessel displayed in the medical image to visualize different simulation of the embolization until an optimal point is reached by the selector, wherein the optimal point is reached so as to reduce cutoff of vessels that supply blood only to healthy tissue and to increase cutoff of vessels that supply blood to the malformation; obtaining a live image of the malformation and the surrounding vessels during an intervention with a catheter to embolize the feeding vessel; overlaying the live image with the medical image; identifying a blood flow direction at the optimal point in the segmented feeding vessel by the processor; and indicating a part of the segmented feeding vessel in the blood flow direction after the optimal point in the medical image by the display device, wherein the part of the segmented feeding vessel is blocked after the optimal point by releasing embolizing material at the optimal point.
