AIM:

The course is designed to make the student acquire an adequate knowledge of the physiological systems of the human body and relate them to the parameters that have clinical importance.  The fundamental principles of equipment that are actually in use at the present day are introduced.

OBJECTIVES:

i.          To provide an acquaintance of the physiology of the heart, lung, blood circulation and circulation respiration. Biomedical applications of different transducers used.

ii.          To introduce the student to the various sensing and measurement devices of electrical origin. To provide awareness of electrical safety of medical equipments

iii.  To provide the latest ideas on devices of non-electrical devices.

iv.  To bring out the important and modern methods of imaging techniques.

v.   To provide latest knowledge of medical assistance / techniques and therapeutic

equipments.
