A new, reliable and inherently safe nasogastric feeding tube position determination system has been developed. The system is particularly useful for preterm born infants. The system uses low-frequency transmit, reflection and receive coils. Transmit and receive coils are positioned in a handheld detection module in such a way that the mutual coupling is minimized, resulting in a good spatial resolution. The reflection coil is positioned at the distal end of the nasogastric feeding tube and uses a diode to double the frequency. The frequency doubling improves the detectability, making it possible to neglect reflected signals at the fundamental frequency. The design is based on analytical sub models and results in a detection accuracy of millimeters.
