During an X-ray fluoroscopy procedure, the position and orientation of an invasive device, such as a catheter, are measured with radiofrequency fields. The invasive device has a transient coil attached near its end and is driven by a low power RF source to produce a dipole electromagnetic field that can be detected by an array of receive coils distributed around a region of interest of the subject. Multiple views of the instantaneous position of the invasive device are displayed by superposition of graphic symbols on multiple static X-ray images obtained at multiple view angles. Each view angle is displayed upon a different display means. The X-ray images are obtained only when deemed necessary by the operator to minimize X-ray dose. A single X-ray source and detector may be implemented since it is not necessary to obtain the X-ray images simultaneously.
