ABSTRACT:
The apparatus (1) is constituted by: device (3) for creating a homogeneous main magnetic static field (HO) orientated along a determined direction (Oz) in which static field there is placed the body (2) to be examined; devices for creating magnetic field gradients in a space of the body to be examined along three directions of the space; radio frequency excitation device (E) and a device (R) for the detection of the nuclear magnetic resonance signals produced by the body to be examined. The one, (Dx) of the devices for creating the gradients is constituted by a unilateral system wherein the device (6) for creating the magnetic field gradient along one direction (Ox) of the space are entirely situated on one and the same side of an "open" surface (P) while the body to be examined (2) is situated on the side of the surface (P) which is opposite to that where the device (6) is located, which are capable of creating a transverse gradient in relation to the direction (Oz) of the main static field, on the side of the surface where the body ( 2) to be examined is situated. Such a device (Dx) is particularly suitable for NMR imaging of the human skin.
