Real-Time Interactive NMR Image Synthesis

A method is presented which allows us to synthesize NMR images for arbitrary pulse sequence timing parameters in real time after user input via trackball. The synthesis is based on calculated proton density and relaxation time images obtained from a special pulse sequence. Due to the real-time operation, the method can be used both as an educational tool and for diagnostic evaluation of images assuring optimum contrast. Details of the technical implementation are given and examples are presented for spin echo as well as inversion recovery images. Finally, alternative means of presenting the density and relaxation time data are discussed which do not relate to certain pulse sequences.
