Tiltingly oscillating ultrasound treatment device

A system for ultrasound treatment, the system comprising:

• an ultrasound device comprising:
• at least one tilting ultrasound transducer, comprising a body interface implement, the tilting ultrasound transducer configured to be deployed and transmit ultrasound energy onto a skin tissue overlying a treatment region of an internal tissue of a treated body part, such that the body interface implement interfaces with a surface of the skin tissue;
• and
• a motor-driven oscillator, coupled with the tilting ultrasound transducer, and configured to oscillate about an oscillation-axis relative to a surface of the skin tissue, such that at least one of:
• a position of the body interface implement;
• and a tilt direction of the body interface implement, oscillates about the oscillation-axis;
• and
• a measurement assembly, configured for measuring body shape parameters of the treated body part with said ultrasound device, the measurement assembly comprising:
• a green screen;
• a plurality of scale-markers, positioned at a predetermined respective distance from each other to form a one-dimensional or two-dimensional plane parallel to the green screen, wherein the one-dimensional or two-dimensional plane is shared by the treated body part;
• at least one imaging device, operational for capturing images of the treated body part and the scale-markers on a background of the green screen;
• and
• a processor, configured to receive the images from the imaging device and to process the images to measure body shape parameters of the treated body part.
