Abstract
Region of interest (ROI) corresponding to a soft tissue mass are tracked in a training video acquired by sonography. The locations of the ROI are used to construct a directed graph in which each node represents a location of the tracked ROI, and the edges represent temporal relations of the ROIs. The soft tissue mass can also be tracked using the graph, and appropriate treatment can be delivered.
Claims25
A computer implemented method for tracking a soft tissue mass, comprising the steps of:
- acquiring a training video of a soft tissues mass inside a body using sonography, in which the training video includes a sequence of images;
- marking a region of interest (ROI) corresponding to a location of the soft tissue mass in a first frame of the training video;
- constructing a directed graph of nodes and edges in a memory while tracking the ROI in each image in the sequence of the training video, in which each node represent a location of the tracked ROI, and the edges represent temporal relations of the ROIs;
- acquire a treatment video of the soft tissue mass using the sonography;
- and
- tracking the soft tissue mass in the treatment video according to the directed graph.
