A method for generation of continuous acoustic holograms is presented and demonstrated. Goal is to generate efficient and uniform acoustic holograms for the magnetic resonance guided focused ultrasound applications. Acoustic fields simulations and magnetic resonance temperature elevation measurements of the first three English letters holograms are presented. The acoustic holograms were generated on relative small areas of 1.5x1.5cm and in sub-millimeter acoustic field resolution to demonstrate the high accuracy and flexibility of this method. By using this technology, the efficiency and safety of focused ultrasound applications, e.g. hyperthermia and ultrasound neural stimulation, could be further improved.
