摘要：
Therapeutic ultrasound applicator is provided for use with magnetic resonance system. An array of many elements, such as a multi-dimensional array, is used. To avoid cabling, the transmitters are positioned at the array. The array and transmitters are shielded to reduce interference. To avoid large inductors for the many elements, an acoustic matching layer may be sized to provide a desired phase angle or electrical impedance matching.
