Abstract: An image processing system and method is provided. The image processing system includes a display, a processor, and a memory. The memory stores processor-executable code that when executed by the processor causes receiving an image of a region of interest of a patient with a medical catheter, tube or line disposed within the region of interest, detecting the medical tube or line within the image, generating a patient coordinate system relative to an anatomy of the patient within the image, generating a combined image by superimposing a first graphical marker on the image that indicates an end of the medical catheter, tube or line, and a second graphical marker on the image that indicates patient coordinate system, and displaying the combined image on the display. In addition, the system assesses common visualizable complications associated with CVC placement, including but not limited to hydrothorax, pneumothorax, pneumomediastinum and CVC position changes between x-rays taken at different times.

Abstract: An eddy-current angular displacement sensor includes a stator including a coil array including N coils, wherein N is an integer greater than 1, one exciting circuit connected via a switching system to the coil array that generates a changing magnetic field, a measuring circuit connected via a switching system to the coil array that generates output signals that depend on the eddy currents caused by the changing magnetic field, and a partially metallized rotor, through which the eddy currents travel, and the angular displacement of which would be determined by the output signals.
