Apparatuses, systems, and methods are provided for growing and maintaining cells. In one embodiment a line card comprises functional circuitry, line card connector contacts and a termination resistor. The conductive pattern of the micro strip line includes a conductive welding portion welded to the internal conductor of the coaxial cable, a conductive landing portion extending from the conductive welding portion in a predetermined width, and an impedance converting portion whose width increases as it extends from the conductive landing portion. A value for the pixel is set to erase the pixel when the resulting convolution value for the pixel is less than a threshold. Various features of the inventive technique include thresholding a 3D CT data set on a voxel basis; and using the Hough transform to identify shapes within the thresholded data that match a predefined 3D shape corresponding to an implanted seed. Several variations of dynamic spinal stabilization devices and systems are described.
