A computer-implemented method for updating a boundary segmentation, the method including receiving image data and an original boundary segmentation including a plurality of boundary points. A plurality of edges in the image data is detected and used to generate an edge map. A confidence for a boundary point in the original boundary segmentation is computed where the confidence is based on a distance between the boundary point and an edge point associated with at least one of the plurality of edges of the edge map, and based on the confidence a classification of the boundary point is determined. An updated boundary segmentation based on the classification of the boundary point is generated and then output.

Updating boundary segmentations

The disclosure relates to a method for determining a boundary about an area of interest in an image set. The includes obtaining the image set from an imaging modality and processing the image set in a convolutional neural network. The convolutional neural network is trained to perform the acts of predicting an inverse distance map for the actual boundary in the image set; and deriving the boundary from the inverse distance map. The disclosure also relates to a method of training a convolutional neural network for use in such a method, and a medical imaging arrangement.
