| titleOfInvention | Apparatus for and method of determining values of relaxation parameters |
| abstract | In an apparatus for determining relaxation parameters T1 and T2, a sample (10) is placed in a constant magnetic field supplied by magnet (12). An rf transmitter/receiver probe (14) is used to apply excitation pulses to the sample (10) and to detect a resonance response signal. The probe (14) is driven by a pulse programmer (16) via a modulator (18), a mixer (20) and a linear power amplifier (22). The resonance response signal is fed to an acquisition computer (24) via a preamplifier (26), an rf amplifier (28), a mixer (30) and phase sensitive detectors (32, 34). An oscillator (36) having a reference frequency synchronises the excitation pulses and the detected signal by means of the mixer (20) and the mixer (30) respectively. Gradient coils (38) provide the gradients necessary for acquiring the resonance response signal, and are driven by the pulse programmer (16) via gradient coil amplifiers (40, 42, 44) using data stored in the waveform memory (46). The acquisition computer (24) processes the acquired resonance response signal to determine values of T1, T2, υ and ς. Images may be produced based on any of these parameters or combinations thereof. A corresponding method is also described. |
