A new fast and quiet method for MRI based on acquisition of time domain signal during ADiabatic sweep excitation is reported. The described approach represents a branch of NMR which by coincidence was not previously developed. The proposed imaging method has reduced motion artifacts because it does not require gradient inversion or the delays associated with forming an echo. The method applies virtually simultaneous excitation and signal acquisition giving significant benefits for studying objects having fast spin-spin relaxation rates. Additionally, gradients do not have to be pulsed and can be run in a small stepwise continuous manner, greatly reducing acoustic noise.
