Aesthetic method of biological structure treatment by magnetic field
In methods for treating a patient, a time varying magnetic field is applied to a patient's body and causes a muscle contraction. The time-varying magnetic field may be monophasic, biphasic, polyphasic and/or static. The method may reduce adipose tissue, improve metabolism, blood and/or lymph circulation. The method may use combinations of treatments to enhance the visual appearance of the patient.
