ABSTRACT:
A magnetic resonance signal of a volume of interest within an object is acquired by placing the object in a magnetic field and the application of three successive steps. The first step comprises an rf selective 90.degree. pulse of frequency f.sub.x applied in the presence of an x-gradient magnetic field to select a slice. The magnetization of the slice is then inverted. In the second step an rf selective 90.degree. pulse of frequency f.sub.y is applied in the presence of a y-gradient magnetic field to excite a strip of the slice, in the third step an rf selective 180.degree. pulse of frequency f.sub.z is applied in the presence of a y-gradient magnetic field to refocus the magnetization of a region of said strip. The resulting free induction signal is derived solely from said region.
