Diagnostic and Therapy apparatus and methods use non-ionizing radiations which are based on integration of nuclear magnetic resonance and radiation manipulation. Quantitative diagnostics integrate the following devices: manual control digital filter/selector (18), frequency matrix monitor (25), frequency image monitor (26), and control panel (28). Therapy integrates the following devices: resonating antenna for radio frequency (4), low radio frequency signal processor/modulator (10), radio frequency pulse amplifier (13) and central pulse control (16). Internal parameters of the emission, such as frequency, power and polarity are selectively manipulated to personalize the therapy and to significantly improve the levels of selectivity and/or differentiation of all the processes.
