Patent ID: 7345478

Claim:
A method for scanning objects comprising: performing a non-phase-cycled excitation-pulse-sequence; adjusting a response to a given quadrupolar substance by calibrating said response to a set of predetermined operational parameters, at least one of the parameters being selected from the group consisting of the pulse separation, τ, the pulse width t p , the frequency offset, Δf, the ambient temperature, T, the maximum velocity expected for said scan-item passing through said probe-sensing-region, v max , the length of said probe-sensing-region, L, and the resonance frequency of the quadrupolar nuclei, ω r ; scanning an object in relative motion with respect to a probe-sensing region, and passing through said probe-sensing region, during sensing; and processing the response to said excitation-pulse-sequence and forming an output-response that indicates a characteristic of the object.
