However, the next generation of biologists was without this benefit, and now technology was advancing rapidly. The need for a bridge between the gap of technical knowledge and biology resulted in the emergence of the biomedical engineer (2). The areas in which engineering blends with medicine are abundant and diverse. Biomedical engineers design imaging and diagnostic instrumentation, drug delivery systems, medical sensors, prostheses, rehabilitative devices, and artificial organs. They develop biocompatible materials, model physioJ.

BIOLOGICAL EFFECTS OF ELECTROMAGNETIC FIELDS A biomedical engineer involved in the study of the biologic effects of electromagnetic fields studies a variety of diagnostic and therapeutic applications of electromagnetic fields and the adverse effects of such fields. The diagnostic uses of extremely low-frequency (ELF) magnetic fields include magnetic resonance imaging (MRI), which also uses a radiofrequency (RF) field, and neural stimulation by strong magnetic pulses. Bone and cartilage repair, soft-tissue healing, and nerve repair or regeneration are among the therapeutic applications under investigation for applications of low-frequency, pulsed electromagnetic fields (PEMF).
