Automatic spacial identification of tissue implanted linear sources using medical imaging

A method for automatically determining position and shape of linear line sources implanted in a tissue using any form of diagnostic imaging is presented. Transaxial images are obtained throughout the subject tissue and converted into a binary image set by simple thresholding. The binary image set is...

More Information
Summary:A method for automatically determining position and shape of linear line sources implanted in a tissue using any form of diagnostic imaging is presented. Transaxial images are obtained throughout the subject tissue and converted into a binary image set by simple thresholding. The binary image set is analyzed for contiguous regions of unit pixel value. An aspect ratio is computed for each contiguous region based on the geometric properties of the region. The linear line sources are detected based on the computed aspect ratios.
