1. An ultrasound treatment system comprising:

  • a primary energy source configured for delivery of a first ultrasound energy;

    a secondary energy source comprising a plurality of mask apertures configured to receive the first ultrasound energy, wherein the primary energy source is configured to concentrate the first ultrasound energy onto the plurality of mask apertures, wherein a first group of the plurality of mask apertures is configured to receive a first portion of the first ultrasound energy and deliver a first distribution of energy fields to a first depth in a treatment region and a second group of the plurality of mask apertures is configured to receive a second portion of the first ultrasound energy and deliver a second distribution of energy fields to a second depth in the treatment region, wherein the secondary energy source is at least partially reflective and reflects a third portion of the first ultrasound energy; and

    either the first depth is different than the second depth or the first distribution of energy fields has a different field pattern than the second distribution of energy fields;

    an ultrasound absorber that is separate from the primary energy source, the ultrasound absorber configured and positioned to absorb the reflected third portion of the first ultrasound energy; and

    an ultrasound emission controller configured to control the emission of the first ultrasound energy from the primary energy source.
