Abstract: A handheld detector gives a warning when a magnetic field exceeds the safety level for a particular medical implant that is magnetically activated. A front surface of the device corresponds approximately to a surface region of a patient's body in a vicinity of an implanted medical device. The magnetic detection element is located at substantially the same distance from the front surface as the control element of the medical device is from the surface region of the patient's body when the device is implanted. The detector element may be activated by a magnetic pressure, that is the vector cross product of the magnetic flux density (B) of a magnet and the applied magnetic field (H), which is less than the magnetic pressure that activates the control element of the implant device. An electronic circuit connected to the detection element may be used to indicate activation of the detection element.

Abstract: The Overhauser effect is a technique for increasing the signal-to-noise ratio of nuclear magnetic resonance signals. Electron spin resonance is set up for example in a contrast agent 14 injected into a patient by means of a transmitter 3 at the end of a probe 1 to excite an area 15. The excited electrons couple to MR active nuclei and increase the population in the higher energy level. Then, when an NMR signal is transmitted and received via coil 5, more MR active nuclei return to the ground state and create a bigger, enhanced, signal detected by the coil 5, hence promoting increased signal-to-noise ratio on an image formed on the monitor 9. In the invention, the Overhauser effect may be applied to an intra-operative situation by means of probe 1 which is inserted, for example, into a patient in a region of interest.
