Fast imaging in liquids and solids with the Back-projection Low Angle ShoT (BLAST) technique

A simple fast imaging scheme is proposed, which is applicable to solid- and liquid-like materials. It is based on low angle pulse excitation in combination with back-projection reconstruction and proper data handling and is called Back-projection Low Angle ShoT (BLAST) technique. The sequence is applied to grape as a biological sample and to a jellibaby (2 kHz linewidth at half intensity) for demonstration of the applicability to solid objects.
