Controlling electromagnetic (EM) transmission based on pressure parameters

A method of analyzing electromagnetic (EM) signal of a human subject, comprising:

• positioning an EM transducer unit in front of a skin area opposite a target intrabody volume of a human subject, said EM transducer unit having at least one EM transducer and at least one pressure sensor;
• measuring at least one pressure parameter indicative of a pressure applied on said skin area using said at least one pressure sensor, wherein said at least one pressure parameter comprises a pressure change pattern;
• measuring EM signal using said at least one EM transducer;
• and
• performing an analysis of said EM signal to infer at least one intrabody parameter of said target intrabody volume;
• wherein at least one of said analysis, a transmission of said EM signal, and a reception of said EM signal is controlled according to said at least one pressure parameter.
